To be honest if it's an emulator issues it's not something I can fix. All I can say is that it works great on Win-Vice 3.5
Yeah I thought as much, and totally understandable. It happens to me on Vice 3.5 on the release and the dailies as well, mainly on PAL. Maybe VICE doesn't like my computer and lags the audio sometimes when jumping and the high-pitch pops are from buffer underruns etc.? Who knows, well anyhow I can play it enjoyable on NTSC though.
