Compiling the Source Code:
--------------------------

Well, for the moment, zsnes source 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.kernel.org/pub/software/devel/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.sourceforge.net),
it will divide its size by 10.


Windows port : 
- GNU Make : it comes with djgpp
- NASM v0.98 : http://www.kernel.org/pub/software/devel/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)
- DX8.0 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). Rename the static version 
		   to 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.sourceforge.net),
it will divide its size by 10.


Linux port:
I assume the standard development tools are installed (gcc, make, ...)
You'll also need : 
- SDL (Simple DirectMedia Layer) : check www.libsdl.org to grab SDL 1.2.0 or
                                   later. If you are using rpm packages, don't
                                   forget the -devel package.
- NASM v0.98 : http://www.kernel.org/pub/software/devel/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
- zlib : http://www.info-zip.org/pub/infozip/zlib/
                                   it is probably already installed on your 
                                   system, maybe you are just missing the 
                                   development headers. Check in the 
                                   packages available with your distribution 
                                   or go to the page above
- libpng : http://www.libpng.org/
                    You might also need libpng, ZSNES will compile without
                    PNG support but I have found doing so to make ZSNES
                    unstable for some weird reason.  If you don't have
                    libpng, either get it and install it or pass the
                    --without-png option to the 'configure' script.

Then to build the executable, go to the src directory and type:
./configure && gmake && gmake install

Note: you require root to install zsnes to the the default (/usr/local/*) 
directory

Also Note: libpng (optional) needs to be recent, or zsnes will not use it 

You may also want to compress the zsnes executable with upx
(http://upx.sourceforge.net), it will divide its size by 10.
