Thanks again, NE1. I looked at the .ini file of my EvoX and it says this:
Section "Emulators"
Item "Arcade","f:\Mame-X\default.xbe"
Item "Atari","f:\Atari\default.xbe"
Item "GameBoy","f:\extremegb\disc\default.xbe"
Item "Lynx","f:\Lynx\default.xbe"
Item "Nintendo","f:\xnes\default.xbe"
Item "Ninteno 64","f:\N64\default.xbe"
Item "Sega Genesis","f:\Genesis\default.xbe"
Item "Sega Master System","f:\SMS\default.xbe"
Item "Super Nintendo","f:\snes9x\default.xbe"
I should be able to just drop the new emulators into the F: drive and they should show up, right? I'm doing that but they still wont show up for some reason. The 'default.xbe' are in the root of the folder too. I don't get it.
