k so i downloaded game boy color A.D. and many more emulators and none of them work. I download roms from my computer but there are zip files, does that have anything to do with it??? Do they have to be roms made specifically for the android??? When im on the emulator, i click to play the roms and the screen goes black for a second then back to the home screen. HELP??? BTW i know some emulators require bios, could someone give me a good link where to get legit bios. Id rather download them on my computer then put them on my phone. THANKS
