I have a PAL MaxPlay game disc by code junkies. When extracting the files for a NTSC conversion, I found GBA Homebrew Roms in the disc. One of the games even has a GBA displayed in the instructions. The MaxPlay is also released for the PAL Gamecube, probably why the games are in GBA format.
The interesting part is that there seems to be a GBA Emulator that runs at decent speed with sound for the PS2. It would be a kick if I can substitute the homebrew games for official game roms such as Mario and install the updated disc in the PS2 Hard drive.
