:::I suspect the 8-bit Nintendo emulator is based on PocketNES (emulator for Windows based Pocket PC's). Just small things I've noticed, for example Mad Max won't advance past the intro screen regardless which buttons are pressed, certain sound glitches in Super Mario Bros, etc. I agree the official SNES emulator is rather poor on the Dingoo, far too slow for most games, to the point I still use my old PocketPC with its SNES emulator instead (it is a bit laggy too, but far better speed and accuracy). I would hope someone ports SNES9x or ZSNES to the Dingoo one of these days
