Compatibility
The GBA rom can be loaded by a GBA emulator like Visual Boy Advance or a real Gameboy Advance using a flash2advance or a similar backup tool.
Note that the rom lacks all the standard copyright and crc infos of Nintendo, and so it's not recognized by GBA as a valid rom. If you are running it on a real console you should use a loader or the Pogoshell.
Changelog
V3.0

- Switched to jpeglib: Improved Jpeg Packing.
