Compiling the Source Code:
--------------------------
Well, for the moment, zsnes sources may be a little hard to compile. Here
is a quick guide (based on my own experience and on a doc written by zsKnight)
explaining how to compile zsnes. With these tools, I can build both dos and
win version, I hope it will also work for you
First, you need the following software:
Dos port :
- NASM v0.98 : http://www.cryogen.com/nasm/
the version found on http://nasm.2y.net/ DOES NOT WORK
with zsnes sources. When you type nasm -r, you must get
'NASM version 0.98' and not 'NASM version 0.98.08' if you
have the correct version
- DJGPP v2 or higher, (GCC also installed) : http://www.delorie.com/djgpp/
using the zip picker, the default choices are ok if you
check C and C++ in the programming languages. You also need
to get zlib which is available with the full distribution
of djgpp. You can get it at :
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2tk/zlib112b.zip
Then to build the executable, go to the src directory and type:
make -f makefile.dos
You may also want to compress zsnes.exe with upx (http://upx.tsx.org), it will
divide its size by 10.
Windows port :
- GNU Make : it comes with djgpp
- NASM v0.98 : http://nasm.2y.net/ or http://www.cryogen.com/nasm/
- MSVC++ 6.0 or higher : not freely available, you'll have to buy it
You need to run VCVARS32.BAT. If you get an
out of environment space error, type 'command /e:32768'
(to create a new command.com entity with more
environment space)
- DX7.0 SDK or higher : you can get it at microsoft.com. It is quite big.
Also, edit makefile.win to set the correct path to your
SDK. I also had some problems with vc++ using its own
(old) directx headers instead of the sdk headers. I replaced
these old headers (in the include directory of vc++ dir)
with the newer ones.
- zlib : http://www.info-zip.org/pub/infozip/zlib/
you need the Win9x/WinNT static library (the dll version doesn't
seem to work with zsnes). Name the static version zlib.lib and
put it somewhere where vc++ will find it (for example, the lib
directory in vc++ dir).
Don't forget to set the correct path to the directx sdk in makefile.win!
Then to build the executable, go to the src directory and type:
make -f makefile.win
You may also want to compress zsnesw.exe with upx (http://upx.tsx.org), it will
divide its size by 10.

Table of Contents
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
I. ) The Game Menu
II. ) The Quick Menu (Arrow Menu)
III.) The Config Menu
IV. ) The Cheat Menu
V. ) The MultiPlay Menu
VI. ) The Misc Menu
----------------------------------------------------------------------------
Note : If any windows exists in the GUI field, pressing ESC always closes
the top-most window
Note : Pressing ESC when no window is active is equivalent to RUN. It will
not function if no game is loaded
Notes on the filename box where you can manually type in the filename:
- Typing text into the box would automatically seek to the closest
matching filename in the box where the file selection cursor is located
- When you press enter with text in the box without any '\' or ':' in the
filename, ZSNES will first look for a directory matching the text and
changes its directory if one is found. Otherwise, it will load the
current file or directory highlighted by the selection cursor.
- You can type in the full filename or directory including path
(eg. d:\games\mario.smc) or the drive name (eg. d:)
----------------------------------------------------------------------------
---------------------
- I.) The Game Menu -
---------------------
Load :
Perform : Load File and Run
Usage :
Loading a File :
You can move through the list using either the mouse or the
keyboard. The keys for the keyboard are :
Up/Down - Move Up/Down through the list
Left/Right - Switch between the File and Directory Window
PageUp/PageDown/Home/End - Move through the list in larger
increments
A .. Z, \, : - Enters filename/directory into the load box
Enter - Load File or Change Directory (depending on which
window you are in)
Display Type :
You can select from either Normal 8.3 file format (Default),
Snes Header name, and Win95 long filename format.
Note : Win95 long filename format will not work in Pure DOS.
It will crash when using dosemu in Linux
Note : Snes Header Display will sometimes display garbled Lines.
This is normal since some images don't have a proper
name in the header or the header is not in english.
Whenever ZSNES detects a blank header name, it uses
the filename instead.
Also note that .ZIP files will not display the header name.
It's not efficient for the program to unzip every zip file
in the directory just to get the header names.
Show all Extensions : This will force the GUI to show
all of the file extensions instead of the default (.SMC,.SFC,...)
Run :
Perform : Runs the game
Reset :
Perform : Resets the game, but asks user for confirmation first
Save State :
Perform : Saves the state (Equivalent to default F2), but asks
user for confirmation first
Load State :
Perform : Loads the state (Equivalent to default F4), but asks
user for confirmation first
Pick State :
Perform : Allows user to select the state position to use
(Equivalent to default F3)
Quit :
Perform : Quits ZSNES
----------------------------------------------------------------------------
-----------------------------------------------
- II.) The Quick Menu (Displayed as an Arrow) -
-----------------------------------------------
Perform : Allows the user to quickly select the last 10 games loaded off
the GUI. Also allows the user to freeze/clear the list.
Tip : You can create a favorites list by first clearing the list then
loading up all the games (last game loaded will be at the top) and
turning freeze on.
----------------------------------------------------------------------------
-------------------------
- III.) The Config Menu -
-------------------------
Input #1-#5 :
Perform : Allows user to select the input device and control
keys for each player
Usage :
Selecting an Input Device :
Using your mouse, move through the list of input devices
until the device of your choice is highlighted. From
there, click on SET and the input device you selected
should appear after CDV: (CDV = Current Device)
Changing default keys :
Click on the key which you want to change using your
mouse and then press the key or joystick button/pad
which you want to change it to. Pressing ESC disables
the game key.
Joystick 209h usage :
Some dual joystick cards support dual joystick ports
(port 201h and 209h) which allows for 2 6-button joysticks
or 2 different types of joysticks (sidewinder and a
standard joystick). If you have one of these, check
the 'Use joystick port 209h' box. If you do not have
a dual joystick/dual port card and if you check the box,
then the joystick will not work.
Options :
Perform : Allows the user to select some in-game options
Usage :
Auto Frame Rate - Enables Auto Frame Rate
Frame Skip - (Shown when Auto Frame Rate is disabled)
Sets the constant frame skip value used when a game plays
Max Frame Skip - (Shown when Auto Frame Rate is enabled)
Sets the maximum allowable frame skip in auto framerate mode
New Gfx Engine - Enables/Disables the New Graphics engine
in 256 color modes or 320x240x65536 mode
VSync - Enables vertical sync wait to reduce sheering of the
screen. Requires a very fast computer.
MMX Copy - Enables MMX Copying routines for a slight speed
increase (MMX processors only)
Use Pl1/2 as Pl3/4 - Allows the user to use 2 devices for 1 player
such as the keyboard and the joystick. (set keyboard as input
device 1 and joystick as input device 3). This, however, disables
multitap support
Sidewinder Fix - Click this when your sidewinder doesn't work
after disabling the sidewinder profiler and pressed the
mode button twice
FPS at Start - Checking this would make the FPS appear whenever
you start ZSNES
Use 30Hz for Turbo - When activated, Turbo will change at 30hz NTSC
or 25hz PAL. Otherwise, Turbo will change at 60hz NTSC or 50hz PAL
Enable Game Clock - Enabling this will show the system clock on-screen
Toggled Fast Fwd - Checking this will change the way how the fast forward
button functions. Having it checked will cause it to act as a switch
and having it unchecked will cause it to act as a push button.
SRam Check+Save - This will enable automatic Save Ram write detection and
save the sram (.srm) to disk approximately 10 seconds after.
Old Gfx Mode 2 - This will enable the Old Gfx Engine Mode 2 which fixes
many transparency bugs that currently plagues ZSNES in the current
engine, however, it also creates some new ones. This mode can be
slower at times so it's recommended that you only turn it on when
you need it.
Start at Latest Save - Checking this will automatically set the
save state pointer (F3 Menu) to the most recently saved location
whenever you load a rom image.
Auto State Save/Load - Enabling this will allow ZSNES to automatically
re-load the state whenever you return back to the game after a
proper exit.
Don't Save Current Path - This will prevent ZSNES from changing the
current start-up game path in the configuration. You can
access this in Config->Options.
Disable Sound CPU Emu - Selecting this would disable the SPC700 chip
that controls the sound. Using this would speed up emulation,
but the drawback is that you won't have sound and the gane
compatibility rate would be lower.
Add-ons:
Perform : Changes the current special input selected for the game
Usage :
None - Uses the regular snes controllers
SNES Mouse at Port #1 - Emulates the SNES mouse at controller port #1
SNES Mouse at Port #2 - Emulates the SNES mouse at controller port #2
Super Scope - Emulates the SNES Super Scope
Lethal Enforcer Gun - Simulates the mouse movements for Lethal
Enforcers 1
Video :
Perform : Changes the current video mode and sets some options
Usage :
Changing the video mode - Use the mouse to select the video mode
and click 'SET'. When the video mode changes and if the result
doesn't look right, wait for 10 seconds without pressing any key
or button and the display will return to the previous one.
Scanlines - Only available in 256x256x256 and VESA2 640x480 modes.
This mode adds a blank line in between every line to produce
a scanline effect similar, if not exact, to a TV.
Eagle Engine - Only available in VESA2 320x240x256. Setting
this would enable the Eagle Engine designed by Dirk Stevens
which basically locates 3 similar colored pixels together
and places a small dot in between to smooth out some graphics.
Interpolation - Only available in VESA2 640x480x65536. Setting
this enable interpolation which basically blends all the
inbetween colors to produce a blurry effect. However, this
slows down emulation.
Full Screen - Only available in VESA2 320x240 and 640x480 modes.
Setting this would scale the image to fit the screen. This,
however, slows down emulation.
Small Screen - Only available in VESA2 640x480 modes. Setting
this would display the image in a small, centered screen. This
greatly improves performance in 640x480 modes.
50% Scanlines - Only available in 640x480x65536 video mode. This
will enable scanline mode except that each line is 50% darker than
the line above it.
25% Scanlines - Only available in 640x480x65536 video mode. This
will enable scanline mode except that each line is 25% darker than
the line above it.
2xSaI Engine - Setting this would enable Kreed's 2x Scale Advanced
Interpolation engine.
Super Eagle - Setting this would enable Kreed's Super Eagle engine.
Super 2xSaI Engine - Setting this would enable Kreed's Super 2x Scale
Advanced Interpolation engine. This mode would require a lot of
cpu power since it is written in C.
Triple Buffering - This will enable Triple Buffering if it is available
on your VESA drivers/Video Card. If it isn't available, then Zsnes
will use simulated Triple Buffering which is slower, but still does
the job. Note that Triple Buffering will not work with 2xSaI/Super
Eagle.
Hi-resolution Mode 7 - Enabling this would activate high resolution
mode 7 whenever standard mode 7 is used within a game. This mode
is only available in video modes that support it.
Sound :
Perform : Allows user to change the sound configurations of ZSNES
Usage :
Enable Sound - Setting this turns on the sound
Stereo Sound - Enables Stereo Sound (Noticably slower though unless
you have a fast cpu)
Sound Rate - To change the sound rate, just click on the box
containing the value to rotate through all the
possible values.
Volume Level - To change, just slide the bar
Disable Noise Sim. (Disable Noise Simulation) - Setting this will
disable the noise filter which corrects many sound effects in
certain games, but will also ruin some others.
Surround Sound - Enables simulated 2 speaker surround sound
Sound Interpolation - Enables Sound Interpolation which smoothes out
the wave forms of lower frequency sounds
Reverse Stereo - This function swaps the L & R volume levels
in stereo mode
Low Pass Filter - The Low Pass Filter, when enabled, will produce
better bass in certain sound effects. However, the side effect
is that the sound will overall be more muffled.
----------------------------------------------------------------------------
-----------------------
- IV.) The Cheat Menu -
-----------------------
Add Code :
Perform : Enter Cheat Code Window and Set the keyboard cursor
on the cheat code entry box
Usage : Type in the code in either Game Genie, Pro Action Replay, or
Gold Finger format, press enter, then enter the description.
Note : Be sure to include the '-' when entering Game Genie codes
Note : You can also quickly modify the value of the currently selected
cheat code (in the browse window) by typing a 2 digit hex number
in the cheat code enter space
Cheat Code Reflector - What this feature does is that it allows a value
of one cheat code to be mirrored from a value of another cheat code. To
enable this option, type an 'R' at the end of any cheat code as the
destination, then type another cheat code (Without the 'R') as the source.
For example, if you want address 7E1000 to reflect the value at address
7F2000 (Whatever value written to 7E2000 from the game will also be
written to 7E1000), enter cheat code 7E1000FFR, then cheat code
7F2000FF (where FF can be any value).
Browse :
Perform : Enter Cheat Code Window and Set the keyboard cursor at the
browse box
Usage : Move through the list using either the mouse or keyboard and
select the cheat code you want to modify. Then click on the
buttons to the right or type in the key of the first letter
of the action.
Actions :
Toggle - Turns a cheat code on or off
Remove - Deletes the cheat code off the list
Save - Saves the current list into a .cht file which will
be located in the save directory
Load - Loads a previously saved list
Fix - Clicking this fixes some cheat codes that don't work,
but it will not always work
You can also toggle a cheat code on or off by double clicking on
them.
Search :
Perform : Allows you to search for values in memory such as life, score,
etc. and allows you to change their values to your own preferred
choice.
Usage :
Select Size : You can choose what data size to search for. If you
know the numerical values of the data you're going to select,
select the smallest number range that fits the data values.
(eg. If you know the value cannot go higher than 50000, then
select 2 BYTES (0..65535) instead of 3 BYTES (0..16777215)).
Sometimes, you don't know the numerical value (in the case of
life bars) and you'd have to guess the size.
Select Format : DEC (Decimal, 0 .. 9), HEX (Hexadecimal, 0 .. F)
Most of the time, it's recommended that you'd use decimal, although
there are some cases that the values in memory are sometimes stored
as hex.
Search Type :
Exact Value Search - In this mode, you have to enter the exact
numerical value that you want to search for. Such as if you
have 3 lives left, then search for the value 3. The cheat
search engine also looks for value - 1 since even if a game
tells you that you have 3 lives left, it stores the value as
2 in memory.
Comparitive Search - In this mode, you select whether the value
is less than, greater than, equal to, or not equal to the
previous value. Such as if you have a life bar and if the life
bar suddenly goes down, go back to the cheat search engine and
select less than to search for any value that has been decreased.
----------------------------------------------------------------------------
------------------------
- V.) The NetPlay Menu -
------------------------
Modem Mode :
NOTE #1 : DOS Compatible modem is REQUIRED!
If you don't know your modem settings and you're in win95/98, go to
Control Panel -> System -> Device Manager -> Modem and select
your modem. Then click on your resources tab and the settings should
be there.
1.) Dial Menu - Allows you to enter the phone number to dial and then
dials and connects
2.) Wait for Ring - Waits for ring
3.) Config Modem - Allows you to configure your modem :
ComPort, IRQ, Baudrate - Sets your modem settings
Use Fossil Driver - Set this option if you want
ZSNES to use your a fossil driver. If you don't
know what a fossil driver is, just leave this
option unchecked and pretend it doesn't exist.
4.) Manual - Allows you to connect manually through the terminal.
However, if both remote and local users select manual,
the player numbers will not be assigned.
IPX :
IPX mode currently connects at the first remote connection it detects.
This will probabily change in the future if there is a demand.
Chat Mode :
Latency - The lower the number, the better the control response time.
But setting it too low can cause a lot of frame skip problems.
This value should vary depending on the traffic of the connection
you are using. A value of 2 or 3 is recommended for modem. The
value for IPX varies. Latency is basically the amount of time
between a user input and that input being affected in the actual
game. The delay should be higher than the time it takes for data
to move from one end to the other. Latency value of 1 is
equivalent to 1/30th of a second on NTSC games or 1/25th of a
second on PAL games.
Player # boxes - This will allow you to select up to a 5 player multiplayer
game. Anything that is checked will be controlled locally
starting from player 1 as the lowest checked player. Anything
marked with an X will be controlled remotely.
For example, if players 2,3,5 are checked and 1,4 are X'ed :
local player 1 will control player 2
local player 2 will control player 3
local player 3 will control player 5
remote player 1 will control player 1
remote player 2 will control player 4
----------------------------------------------------------------------------
----------------------
- VI.) The Misc Menu -
----------------------
Game Keys :
Perform : Allows user to change the game keys to their own preference
Usage :
Click on the key which you want to change using your
mouse and then press the key or joystick button/pad
which you want to change it to. Pressing ESC disables
the key.
GUI Options :
Perform : Allows the user to customize some of the GUI
Usage :
Mouse Wrap - Allows the mouse pointer to wrap at the borders of the
screen
Mouse Shadow - Disables/Enables the Mouse Shadow
Keep Menu Positions - When enabled, re-entering the GUI from the
game does not automatically enter the Load Menu, but
the previous menu which you were on when you last exit
the GUI
Save Window Positions - When enabled, the GUI doesn't reset the locations
of the windows when you exit/enter the GUI
Click Enters/Exits GUI - When enabled, it allows the right mouse button
to automatically run and exit the game to the GUI. This
however, slows down emulation by a bit since it has to
check the mouse button status once in a while. In the
windows port, the right click button won't return back
to the game.
Use JoyPad1 to Control - When enabled, it allows Player 1's device
to be used to move through the GUI. This is mainly used
if you want to use your joystick in the GUI. The equivalent
SNES keys to the Keyboard keys are :
SNES ControlPad = Move
SNES A = Enter
SNES B = ESC
SNES L = PageUp
SNES R = PageDown
Enable Water Effect - Enables the water effect in the GUI background
Enable Snow Effect - Enables the snow effect in the GUI background
Key Comb. (Key Combination Editor) :
Perform : Allows you to specify certain keyboard combination routines
with a single keystroke/joystick button press.
Usage :
Description - Allows you type in the description of the combination key
Key - Clicking on this box will allow you to select which key/button to
use
Combination Keys - this window will display the sequence of events
selected by the user
P# - Selects which player # to use those keys as
> = Last </> - Enabling this would mean that the event symbol > will
mean the last left or right direction the user presses in the game and
the symbol < is the opposite of that direction. When disabled, > means
right and < means left.
Game Specfic (Game Specific) - Enabling this will tell Zsnes to use
separate Key Combination files for each individual game.
Clear - Clears the current key combination field
Add - Adds the key combination fields below as a new entry
Replace - Copies the contents of the key combination fields below
to the current highlighted key combination above
Delete - Deletes the highlighted key combination above
Events:
Press+Rel - The key will be pressed and held. It will be released
once another key is pressed after any amount of frame or second
delay.
Press Only - The key will be pressed and held
Rel Only - The key will be released if it is Pressed
by a pressed only event
Frame Delay - Delays for the specified number of frames
Second Delay - Delays for the specified number of seconds
Del - Deletes the event at the end of the Combination Keys list if
one exists
Note : A 1 frame delay exists after the combination key list has finished
processing
Example Key Combination: (Down / Down+Right / Right / L) :
Method 1:
Press+Rel Down / 2 Frame Delay / Press+Rel Down / Press+Rel Right /
2 Frame Delay / Press+Rel Right / 2 Frame Delay / Press+Rel L
Method 2:
Press Only Down / 2 Frame Delay / Press Only Right / 2 Frame Delay /
Rel Only Down / 2 Frame Delay / Rel Only Right / Press Only L
Movie Options :
Perform : Allows you to record SNES Movies so that you can play them
back at a later date either to amuse your friends, torture
your friends, or whatever. Just don't play anything in
front of your enemies since they might break your computer.
Usage :
Movies are saved as .ZMV, .ZM1, .ZM2, etc. files. They should be
located in the same directory as your save files. A movie file
consists of a save state file, saveram data, and the recorded
controller data. The initial filesize of a .ZMV file is the
combination of a .zst and a .srm file (around 300kbytes) and
it averages around 7kbytes/minute (value varies) or 420kbytes/hour.
You can record :
- Standard 1/2 player games
- 3-4 player Multitap games
- SNES Mouse games
- Network/Modem games
You cannot record :
- Super Scope Games
GUI Usage :
Record - Begins recording the movie file
Play - Begins playing the movie file
Stop - Stops the movie process
The numbers at the right side selects which movie file to play/record.
NOTE : Movies recorded without sound cannot be played when sound
is enabled and vice versa
NOTE : Loading another game, loading a state, or resetting the
game will halt the play/record process
NOTE : When you play a movie file, the SRAM data becomes invalid and
ZSNES won't save it until you load a game. This way, you don't have
to worry about your save ram when you load up a movie file.
Save Cfg :
Perform : Saves the configuration files
About :
Perform : Just displays the version # and the authors of ZSNES

- 32MB of RAM (min 17.0MB free)
- VGA card
- Sound Blaster 16 or 100% compatible
Recommended System for SA-1 support : (Mario RPG)
- Fast Pentium processor (P200 or higher)
- 32MB of RAM (min 17.0MB free)
- VGA card
- Sound Blaster 16 or 100% compatible
- You need 17.0MB of RAM to run 48mbit(6megabytes) roms.
- An FPU is required for DSP1 emulation
For SuperFX and SA-1 emulation, 17.0 megabytes of free memory is required
to run.
---------------------------------------------------------------------------
4.) Things you should know about ZSNES
---------------------------------------------------------------------------
- You can use both keyboard and joystick for player 1 or 2 with some
configuration adjustments. Refer to zsnes.faq for details
- If your sidewinder support doesn't work, a quick way of getting it to
work is to fully disable the windows driver from the control panel
- For modem mode, if you don't have a 16550A UART compatible modem
(It will tell you when the modem initializes), chances are that both
sides will go out of sync.
- IPX support seems to randomly lose packets in certain network
configurations which causes both sides to go out of sync
- Several special chip emulation (SA-1) have unknown bugs to
them
- Transparency effects are only available in 65536 color mode
- Using 320x240 resolution modes are faster than 640x480 modes. Use
640x480 modes only if you can't run 320x240 modes or if you want the
added features of 640x480 modes
- To view 512 resolutions properly, use 640x480 mode. Only a few games
uses 512 resolution. One way to find out is to see if a game has
that feature is to look for text that looks squished.
- In 640x480 resolution, the image is scaled so it will look like 320x240
resolution. Only use 640x480 resolution if you want to use scanlines,
interpolation, or if 320x240 doesn't work.
- SuperFX can be slow because it is an extra 10/20mhz cpu that has to be
emulated as well as the snes emulation
- Screen Snapshot and FPS counter are available through a menu by pressing
F1 during emulation
- Screen Snapshot currently saves as Image.PCX (256 colors) and Image.BMP
(65536 colors). This may change in the future.
- FPS counter currently only works when auto frame rate is on.
- To use the cheat function, be sure to have the ROM which you want to
patch loaded already.
- If the cheat codes do not work, chances are that you are using a different
version of the rom that was originally used to create them or the codes
are converted incorrectly from other code formats.
- Certain video cards/monitors cannot support ModeQ (default resolution)
If your video card/monitor doesn't support it, run ZSNES with -v 0.
If -v 0 doesn't work, use -v 2 (vesa 2 required)
- 16 bit mode in ZSNES requires a Scitech Display Doctor (v5.3+) to provide
high color, low resolution modes. You can obtain this software at
www.scitechsoft.com. If your video card already supports lo-res,
hi-color, then don't worry about getting this driver.
- There are still many bugs left in ZSNES so don't expect it to run all
your favorite games.
- VSync won't run well unless you specify a frame skip (eg. -f 0) But
this feature is highly recommended to be used on very fast machines
(eg. Pentium IIs)
- SNES Mouse support is still missing some features such as speed settings
- Pressing the Fast Forward key is equivalent to running ZSNES using -f 9
- If ZSNES doesn't work for you, then don't use it. Use SNES9X, NLKE,
SNEESE, or SNEMUL instead! In fact, even if you use ZSNES,
use those emulators too!

---------------------------------------------------------------------------
6.) Future Progress
---------------------------------------------------------------------------
This section is removed
---------------------------------------------------------------------------
7.) ZSNES Default Keys
---------------------------------------------------------------------------
Here are the default keys while running the emulator. They can be changed
through the GUI except for F1 and ESC :
Disable Backgrounds 1,2,3,4 = 1,2,3,4
Disable Sprites = 5
Panic Key (enable all) = 6
Enable SNES Mouse/SuperScope = 7
Enable New Graphics Engine = 8
Disable Windowing = 9
Disable OffsetMode = 0
Fast Forward Key = ~
PopUp Extra Menu = F1
Save State = F2
Switch State = F3
Load State = F4
Disable Sound Channel = F5 - F12
Quit = ESC
Here are the default keys for the game play (unless modified through the GUI):
Player 1 :
Up,Down,Left,Right : Cursor Keys on Numerical Pad (You can also use
the non-numerical pad, but numerical pad is
strongly recommended)
A,B,X,Y : Home, End, Insert, Delete
L,R : Page Up, Page Down
Start, Select : Enter, RShift
Player 2 : (You need to enable Player 2)
Up,Down,Left,Right : K, M, N, <
A,B,X,Y : D, X, S, Z
L,R : F, C
Start, Select : Ctrl, Alt
To run the emulator, just type ZSNES <romname.smc/.sfc/.fig/.1>
To run it with sound, type ZSNES -s <romname.smc/.sfc/.fig/.1>
To run it in 16-bit mode (VESA2 w/ video card that supports 320x240x65536
required), type ZSNES -v 3 <romname.smc/.sfc/.fig/.1>
or with sound, type ZSNES -v 3 -s <romname.smc/.sfc/.fig/.1>
---------------------------------------------------------------------------
8.) Extra Pop-Up Menu (F1 Menu)
---------------------------------------------------------------------------
Save Snapshot - Saves a snapshot as either .PCX (8-bit color) or .BMP
(16-bit color)
Show/Hide FPS - Shows or hides the frame per second display which appears
on the bottom-left corner of the screen. This can only
be enabled in auto-frame rate mode.
Save SPC Data - Selecting this will search for the beginning of the next
song and save the data into a .spc file which saves it
similarly as a .srm file. To capture a song, it is best
recommended to initiate this feature approx 2 seconds
before the next song starts. This does have potential to
fail though so don't expect it to work all the time.
Also, this feature doesn't work in the new gfx engine.
Sound Buffer Dump - This dumps the sound buffer in zsnes and also filters
out any unoccupied space. The sound buffer contains
decompressed samples which are written to when zsnes
plays/decodes a sample from sound memory. Because of the
way zsnes buffers the sound data, this can produce
inaccurate results.
Snapshot/Increment Frame - Same as snapshot, but it returns to the F1 menu
after a couple frames. Useful for making animations.
---------------------------------------------------------------------------
9.) Configuration File (ZSNES.CFG)
---------------------------------------------------------------------------
Almost everything in zsnes.cfg should now be editable through the gui
---------------------------------------------------------------------------
10.) Cheat Codes
---------------------------------------------------------------------------
Currently, ZSNES supports Game Genie, Pro Action Replay and GoldFinger codes
Here are the steps to get the codes working :
1.) Load the ROM which you want to patch
2.) Exit to the GUI, enter the code of your choice in the cheat menu
3.) After that, you may have to RESET the game to get the cheat code to
work. Sometimes, it is not necessary. You also may have to click
on the FIX button.
NOTE : Some cheat codes are meant to be for different versions of the game.
If a cheat code doesn't work and there is one for both Game Genie
and Pro Action Replay, try them both.
---------------------------------------------------------------------------
11.) Extra Features (SNES Mouse/Super Scope/SuperFX/DSP1/MultiTap)
---------------------------------------------------------------------------
To Enable SNES Mouse, Press 7 once for 1st player and twice for 2nd player
To Enable SNES Super Scope, Press 7 three times
To disable either one, either press 6 or press 7 until you see a disable
message onscreen.
Here are the controls for the Super Scope :
Fire = Left Mouse button
Cursor Mode Button = Right Mouse button
Pause = Backspace Key on keyboard
Enable/Disable Autofire = =/+ key on keyboard, should be located to the
left of the backspace key
DSP1 is enabled automatically. Currently, it runs mario kart and some other
games, but it does not run pilotwings due to a lack of dsp1 functions
that are implemented.
Zsnes auto-detects the SFX emulation from the header and enables it when
found. Also, take note that the SFX is an additional 10Mhz(Ver1) or
20Mhz(Ver2) chip which also has to be emulated with the snes and will
most likely produce a very noticeable slow down in emulation if you
don't have a fast computer.
Sometimes, the Multitap isn't compatible with some games. If that happens,
disable Multitap by setting Player3,4, and 5's input device to 'None' in
the GUI
IPS patcher :
Rename your .IPS file to the rom filename with the .IPS extension
(eg. If your rom is SD3.SMC and your rom is SD3V05.IPS, rename SD3V05.IPS
to SD3.IPS)
and ZSNES will patch the rom realtime without modifying the rom file's
contents.
---------------------------------------------------------------------------
12.) Bugs Section
---------------------------------------------------------------------------
- 65816 lacks correct timing. Although ZSNES bases the timing on a
variable cycle/instruction, it does not deduct correct values such
as 16bit instructions should deduct 1 more cycle than 8bit instructions.
100% cycles of zsnes isn't 100% cycles of a snes because of that.
This means that a lot of games either won't run or will produce horrible
displays. Sometimes adjusting the % of execution can fix those problems.
This is due to inaccurate documentation used when the 65816 was written.
There is no plans on re-writing the 65816 timing yet.
- Games sometimes tend to not display things properly because of graphic
features that aren't implemented yet
- The Sound DSP chip still has its bugs (not many though)
---------------------------------------------------------------------------

---------------------------------------------------------------------------
14.) The Debugger
---------------------------------------------------------------------------
Note : The debugger is disabled when you don't enter zsnes with a -d
Here are the keys:
1 : Enable/Disable spc700 display
2 : Enable/Disable 65816 display
T : Trace (in 65816 opcodes)
B : 65816 break point
S : SPC break point

D : Debug Dump (SPC/DSPRam Dump Only)
W : Break at signal (Used only by the programmers)
F1 : Exit debugger and return to Game
F2 : Save State
F4 : Load State
ESC : Exit entire program
---------------------------------------------------------------------------
15.) Error Codes
---------------------------------------------------------------------------
Unable to Initialize VESA2 :
VBE not detected - ZSNES Failed to detect any VBE interrupts
(Your video card doesn't support VESA)
VESA not detected - ZSNES Failed to detect any VESA extensions
(Your video card doesn't support VESA)
VESA 2.0 or greater required - Your video card supports VESA, but
it has an old version of VESA. You may want
to use SDD (www.scitechsoft.com) to upgrade
your vesa driver unless you have an S3 video
card which you can get a vesa 2 driver from
www.s3.com.
VESA2 mode does not work on your video card/driver - Meaning that the
resolution you chose does not exist in the supported
resolutions of your video card. Chose a different
resolution or upgrade with SDD which can sometimes
help increase the number of resolutions supported
Unable to initialize video mode - A VESA 2.0 driver is found, but the video
mode failed to start. Possibly an error on the
video card setting or a defective hardware
Linear Frame Buffer not Detected - Meaning that your video card does not
support linear frame buffering which is required
for ZSNES' vesa 2 routines
Modem Mode :
Modem Response Timeout - If this appears, then either your modem isn't
configured properly (Even though your COM port is
set up properly, chances are your IRQ isn't), some
other application is using the modem (such as an
internet connection), you don't have a DOS
compatible modem, or your baud rate isn't set up
to the speed of your modem (this isn't required for
all modems though, but for some, it's required)
Cannot Init Driver - This means that you have the FOSSIL DRIVER option
checked, but no fossil drivers are loaded
Carrier Detected (When you're not connected) - This Probabily means that
you have set your COM Port/IRQ incorrectly. This
also might mean that you don't have a dos
compatible modem or the modem is being used
somewhere else such as an internet account.
After Connection (Modem and IPX Mode) :
Incompatible Version - This means that both sides are using different
versions of zsnes. Both sides must use the same
version in order for remote play to proceed.
Invalid Sound Setting - This means that one side has sound disabled while
the other has it enabled. Both sides have to either
have sound disabled or sound enabled because the
game timings of both settings are different.

************* SOUND COMPATIBILITY ISSUES: *************
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How come I don't get any sound?
A : There could be several situations :
1.) You haven't enabled sound. You can enable it through the GUI
2.) Try ZSNES Version a instead of c (eg. If you have ZSNES v0.900c,
download ZSNES v0.900a)
3.) Your windows 95 doesn't create a SET BLASTER string. To verify this,
type SET in DOS and look for a string starting with BLASTER=
If such a string exists, then this is not your problem.
4.) You don't have a SB2.0 compatible sound card. If this is your
case, then there is nothing you can do at the moment. ZSNES
uses auto-initialization mode for sound which requires SB2.0+
5.) Your SB IRQ conflicts with another device. If this is the case,
then you might want to check your sound card settings through
Control Panel -> System.
6.) Zsnes doesn't like your sound card
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : When do you think you'll support GUS/PAS sound cards?
A : We've considered implementing those sound cards, but a lack of time
and also by the fact that we haven't really touched those cards before
prevents us from implementing it.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : I get a sound initialization error using my SB Live! (or any other PCI
card) How do I fix it?
A : Here is a solution : (Thanks CyberGodz for the post on the wwwboard!)
SB Live uses what is known as a NMI or Non Maskable Interrupt to emulate
SB 16 sound. Don't ask me exactly what it does (it's a type of IRQ) but
that is pretty much all it is good for.
The problem is that many boards either lack NMI support or don't have it
enabled. (No NMI = No Dos Support)
To try and solve this problem do the following :
1. Check your BIOS. If there is an option for RAM Parity Checking ENABLE IT.
It usually turns on NMI support. If there is something that says NMI turn it
on
2. If you don't find anything in your BIOS, then go to your motherboards
website and download the latest BIOS flash. Install it and try your dos
sound. (You may still have to enable the stuff in the BIOS after)
3. Failing the first two things you will either have to get a new
motherboard or install a SB 16, or other Compatable sound card alongside
the Live. Just attach a cable from the Line Out of the SB 16 to the Line In
of the Live. Enable line in on the mixer of your SB Live and it should route
the sound through the old sound card. (Don't use the SPDIF to connect the
cards if you have one. Wave sound dosn't pass through SPDIF only MIDI)
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
************* TRANSPARENCY ISSUES: *************
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Are there transparencies in ZSNES?
A : Yes. Transparencies are in zsnes.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How do you enable transparencies?
A : First, try setting the video mode to a 16bit color video mode in
the GUI (If 320x240x16b doesn't work, then try 640x480x16b). If
it gives you an error that says that your video card isn't compatible
with vesa 2.0, you might want to get the Scitech Display Doctor which
is located at www.scitechsoft.com which provides certain cards with
vesa 2.0 support. Running with transparencies on is definitely slower
because of the extra math equations, memory, and video space involved.

Q : There is this layer of fog blocking my view. What's wrong?
A : You need to either enable transparencies (see above) or you can
disable certain backgrounds by pressing the 1,2,3, or 4 keys. If
you get lost while pressing those keys, press 6 to re-enable all
the backgrounds.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : Why doesn't *name of game* work on zsnes?
A : Getting the compatibility higher is a very hard task to do. We're always
trying to get more games working.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Can you get *name of game* working by the next release?
A : We're always trying, but we can never guarantee a specific game will be
working because of the difficulties involved in bug fixing.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why is *name of game* not working in v.*version #* of zsnes? It
was working before.
A : Whenever we change something in the emulation, whether it's optimisation
or bug fixes, it has a good potential to have caused a problem elsewhere.
Usually, these problems aren't discovered until after a release.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : When do you think you will emulate the *DSP/SFX/C4* chip? My favorite
game *name of game with chip* won't run without it.
A : We will consider emulating extra chips only if decent information on
those chips are found. However, even if we find info on them, we
cannot guarantee to be able to implement them.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : This game tells me that it is not compatible with the MultiTap.
What should I do?
A : Set both Player 3 and Player 4's input device to 'None'
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How do I improve the compatibility of ZSNES?
A : Turning on sound helps a lot here. If you can't enable sound, run
zsnes using the commandlines -s and -dd. Also, try to keep the % of
execution at 100%. If a game still doesn't work, try tweaking
the percentage of execution to both 120% or 80% in zsnes.cfg. If
that still doesn't work, then it's either a corrupt rom, a game that
requires a special chip, or a bug in zsnes.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How come Mario RPG doesn't work?
A : If the emulator crashes, then your rom file is corrupt. If it only
displays a blank screen, then you need to enable sound (or use -s -dd
as the commandlines when running zsnes under dos)
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why am I experiencing problems with Chrono Trigger?
A : - If there is a layer of fog blocking the view, then you need to either
enable transparencies or remove the fog layer by pressing one of
the 1,2,3 keys.
- If the game freezes after the switching character sequence, then
you need to enable sound (or use -s -dd as the commandlines when running
zsnes under dos) and do not load from a save state, instead load from
the game selection menu when you start the game normally.
- If you cannot press the L+R+A seqence, then you would need to assign
both the L and R key as the same key such as set L and R to PageUp and
set A to Home, then pressing PageUp+Home will be the same as pressing
L,R, and A together. This is a hardware limitation of the keyboard,
not a bug in zsnes.

Q : Why doesn't MegamanX2/MegamanX3/Star Ocean/Street Fighter Alpha 2 work?
A : Star Ocean and Street Fighter Alpha 2 both uses the S-DD1 chip, which
uses an unknown compression routine that has to be figured out before
it can be emulated.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why doesn't MegamanX2/MegamanX3 work?
A : If it crashes after the Capcom logo, then you have a corrupt rom dump.
The actual ROM size for both of them is about 2 megabytes.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Can you guys get Star Ocean/Street Fighter Alpha 2
to work?
A : We have already worked on them to an extent, however, we cannot go much
further until we gain knowledge on how to get them to work.
Unfortunately, we are not magicians.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : How do I speed up zsnes?
A : Running zsnes under pure dos instead of in a windows box would help for
low-end systems.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Can you implement dynamic recompilation into zsnes?
A : There is no plans to implement it since it doesn't seem necessary.
The snes only uses a 3mhz cpu compared to say a 33mhz on a playstation
or a 93mhz on an n64. Implementing a dynamic recompilation engine will
be hard work and won't improve performance by much.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why does the game slow down even though I'm using auto frame rate and
the FPS is pretty high?
A : A game slows down like that when it executes its code beyond the speed of
cpu emulation that zsnes currently handles. To reduce such slowdowns,
increase the percentage of execution by using either -p or editing
zsnes.cfg.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : Why can't I press more than 2 keys at a time?
A : It's mainly the limitation of the PC Keyboard. If you want to press
more than 2 keys at a time, either use a joystick or change the keyboard
keys around until you find a combination where you can press more than
2 keys at a time. Another technique that works is to set multiple
buttons to a single key. That way, pressing that key presses multiple
buttons at the same time.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How come my sidewinder pad doesn't work?
A : First, for non-USB Sidewinders, the first thing you should try
is to first disable the sidewinder profiler from the Win9x icon
tray, run ZSNES, set Input #1 as SidewinderPad1, then press the
mode button a few times. If it doesn't work, then try the
following :
- Disable the Win9x Sidewinder Profiler, run Zsnes and press the
Mode button a few times
- Try checking or unchecking the Sidewinder Fix in the Options menu
of the GUI and repeat the above steps
- Fully disable the Win9x Sidewinder Drivers by going to
Control Panel/Game Controllers. Then remove the sidewinder
(Thanks Scarlet-Slider for this info!)
- Run zsnes under pure dos
- Try checking or unchecking the Sidewinder Fix in the Options menu
of the GUI and repeat the above 2 steps
- Make sure your sidewinder is plugged in and not broken
For USB Joysticks, you can either set ZSNES as a 6-button joystick
or simulate keyboard keys through the Sidewinder Profiler and
set Input #1 as a keyboard with those defined keys.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How do I use more than one sidewinder pads?
A : First, run ZSNES, temporarily disconnect the second sidewinder pad
from the first one, get the first one to work, then re-connect
the second sidewinder pad.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why doesn't my Gamepad Pro work?
A : For the non-USB version, be sure to have your Gamepad Pro set on 'GrIP'
mode. Then set the input device as Gamepad Pro P0. For the USB version,
you can use a keyboard emulator which should be included with the
software that came with your joystick.

Q : Why doesn't my joystick work anymore?
A : You might have accidently clicked the 'Use Joystick Port 209' check box.
Just uncheck it.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How come my joystick keeps holding in one direction?
A : That happens when you hold a direction when ZSNES starts up.
If that happens, then exit ZSNES and reload to recalibrate. Clicking
on SET in the input device window also calibrates the joystick, but
it also resets the controls to the default joystick settings.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : How do I use both my Keyboard and Joystick for the 1st player like
v0.400?
A : In the GUI, enter the CONFIG -> OPTIONS menu. Then check
'USE Pl1/2 AS Pl3/4'. Once you've done that, Player 3 controls
will control Player 1 so if you have joystick set on Player 1,
set Player 3 as keyboard. This disables multitap emulation however.

Q : Why does JB5/JB6 keep getting pressed whenever I try to change a key?
A : Try changing your joystick type from a 6-button to a 4-button.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : Why does ZSNES produce a lot of static?
A : Try reducing your sampling rate or disable stereo sound
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : How come the game genie codes don't work?
A : You probabily didn't insert the '-'. Otherwise, try clicking on the FIX
button once while the highlight is over the code. If it still doesn't
work, chances are that the code is for another version of the game you're
trying to run or the code is a fake.

Q : How do I use .CHT files?
A : Copy the .CHT file to the ROM Directory or if you have a save
directory defined, copy it to the Save Directory. Then rename
the .CHT file if necessary so that the filename before the . matches
the ROM file.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : How come ZSNES freezes when I run it under pure dos?
A : Try loading your mouse driver or run zsnes using -j. For the most
compatible result, use the Microsoft Mouse driver if possible
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : When I load a ROM, how come ZSNES crashes?
A : It could be that ZSNES doesn't recognize your sound configuration
so to fix it, disable sound or try changing your sound configuration.
It could also be that the ROM you're loading isn't compatible with
ZSNES.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Q : ZSNES gives me an out of memory error and I only have 16MB of RAM.
How do I fix this?
A : First, create a shortcut to the DOS Prompt on the desktop (the filename
that it points at can be c:\command.com )
Then right-click on the icon and go to properties.
Select the memory tab and look below for Protected Mode (DPMI) settings
and set a high value (like 20000).
Then double click on that icon and load ZSNES as usual.

Q : How does the auto .IPS patching feature work?
A : The auto .IPS feature works by copying the .IPS file to the directory
of your ROM file or if you have a save directory defined, then the
.IPS file goes into the save directory. Next, rename the .IPS file
so that it matches filename (eg. If your ROM filename is THISGAME.SMC,
then your .IPS filename is THISGAME.IPS.)
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Does the modem mode work well?
A : It should work quite well. First, make sure that you are using a modem
that is compatible with dos (a non winmodem). It is recommended that
both sides has a modem that uses a 16550a UART, otherwise the game may
go out of sync. Also, be sure to load a fresh new Zsnes session before
starting a modem session. If it still doesn't work, then try running
Zsnes under pure dos since some modems doesn't seem to work in
windows in Zsnes while works in pure dos.

Q : Why is modem mode so choppy and slow?
A : Try increasing the latency value one by one until the gameplay becomes
smooth
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Does the IPX support work well?
A : No. It does not work very well unless you have a very fast LAN.
Otherwise, the game will easily go out of sync.
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ
Q : Why does ZSNES display a blank (or messed) screen when I start it up on
my laptop?
A : Your laptop is probably not compatible with ZSNES default 256x256x256
resolution. One way to fix it is to set the resolution to 320x240x256
by using the DOS commandline -v 0.

Q : Can I run .ZIP files from the commandline?
A : Yes. But you have to specify the full path/drive
(eg. ZSNES D:\GAMES\GAME.ZIP)

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

;My current method of cycle detection is to look for 15 highs in a row on
; the strobe line. Cycle ends is detected by 15 lows in a row.
;Mode A has 15 strobes in a cycle, Mode B has 5.
; Note that the 15 highs/lows for cycle detection may be too high for slow
; machines. I havn't seen a problem yet, but it may exist...
;Multiple Sidewinder data complicates things. Each additional SW tags
; another set of strobes to the cycle, 5 more in mode B, 15 more in mode A.
; Detecting extra SW gamepad data is fairly simple: count the number of
; strobes. If it is a multiple of 5, you're in mode B and can divide by 5
; to get the total number of gamepads. If it's divisible by 15, use mode A.
; However, this method cannot distinguish between mode A for one SW and mode
; B for three SW. In that case, the SWCount variable must be set correctly.
