try not to use or go over a 16mb rom file..and try putting in the roms only one at a time. you seem like you know what your doing when it comes to getting other things to work on your psp, so i wont help with that. anyway, try renaming the rom to "rom.gba". well i mean, you dont have to add the extension ".gba" if it's already there, but i think you get it. i dont recommened using it though, it's slow and has no sound, and bad compatibility...
