While MUGEN would be fantastic to have on the GP32, there is one thing people should realize. MUGEN uses a 6-button fighting system. Not all games built with MUGEN use all 6 buttons, so this is not a serious problem. For example, one of my favorite fighting games is DBZ Millenium - a MUGEN game. Most of the characters use either 3 or 4 buttons, so it would be perfectly playable on a GP32. I just want to point out that not every MUGEN game available will be playable on the GP32.
