I have recently downloaded and compiled some emulators. The genesis one and the super nes one... the Sega one works fine... the super nes one has worked once... i have tried to put the mario games into the rom file only and it boots up to the disclaimer then the screen falshes on to black then nothing else..... what am i doing wrong ?? Please help

you need to place at least 20 roms in it for it to work. i suggest puttin in 25 different roms
