tmx2gba is a simple command line utility that converts Tiled .tmx maps to Game Boy Advance compatible charmaps. Originally developed for my own personal use, I've thrown it up on glorious Github/Gitlab/whatever in case this is of use to anyone else.

If you find a bug, please open an issue.

Enjoy!

Features

Exports to raw binary that can be easily memcpy'd into VRAM.
Preserves tile flipping.
Supports per-tile palette specification.
Custom collision layer support.

How do I use it?

tmx2gba [-h] [-r offset] [-lyc name] [-p 0-15] <-i inpath> <-o outpath>

Command	Required	Notes
-h	N/A	Display help & command info.
-l (name)	No	Name of layer to use (default first layer in TMX).
-y (name)	No	Layer for palette mappings.
-c (name)	No	Output a separate 8bit collision map of the specified layer.
-r (offset)	No	Offset tile indices (default 0).
-p (0-15)	No	Select which palette to use for 4-bit tilesets.
-m (name;id)	No	Map an object name to an ID, will enable object exports.
-i (path)	Yes	Path to input TMX file.
-o (path)	Yes	Path to output files.
-f	No	Command line instructions list for easy integration with buildscripts

How do I build it?

Dependencies for building are CMake 3.x and a C++11 compliant compiler, all other dependencies are in-tree so you should be able to build with:

mkdir build && cd build
cmake ..
make

Optionally, to make it convenient for my dkp projects:

sudo cp tmx2gba $DEVKITPRO/tools/bin/tmx2gba

Todo list

Add support for multi-SBB prepared charmaps.
Test CMakeLists for Windows compatibility.
Check if this works for NDS as well.
Compression support.
Prehaps use GNU style getopt_long?
Refactor & Fix bugs. (duh)
