I'm trying to play Sonic 1 on the Genesis Plus emulator. I just can't get it to work properly. My Wii is PAL. In the emulator you can switch between NTSC and PAL. But both don't work 100% right. In NTSC mode, speed and sound seem to be fine but the framerate is terrible, it's very choppy. In PAL mode, framerate is perfect, but the gameplay and sound are definitely too slow. Any way I can fix this?
