Not sure if many GBAtempers have this device but it can't hurt to ask. I bought a Doctor V64 off ebay as a present for myself. I only managed to get round to testing it today since the N64 console was in another place. Anyways, I burned 3 N64 roms to a CD and tested it. Some of the games refuse to load while others loaded.... then went black and another gave me an error message. Granted the N64 rom pack I downloaded had 5 different versions for one rom. Is it normal to not expect 100% emulation or is there something I'm doing wrong?
