I just recently had my Xbox modded by a friend and on it I have NES, SNES, Gameboy and Genesis. However, the main thing I really wanted was a MAME emulator. He placed MAMEox on it, but I have had nothing but trouble with it. I uploaded about 4-5 dozen of my favorite ROMs to it, but only about a dozen work. Can anyone give me some assistance as to how I can get this working or is there a better MAME emulator out there? I must warn you, I'm pretty clueless when it comes to all this modding stuff, so please have patience with me as I'm sure I'll be asking A LOT of questions. Any help is super appreciated!
