I noticed the same issue. If I read things correctly we are using an older emulator core as it tends to run faster. I think there have been a lot of SNES emulation fixes which are not currently on the RPI.

Yeah, I think SNES emulation still has a long way to go on the Pie but it should be doable as long as there interest in the project. I see no reason why this console can’t be emulated at a truly enjoyable speed for most games. Not gonna hold my breath to much for N64 though, sure Mario 64 and Mario Kart will reach playable speeds but doubt that the whole N64 library will run at those speeds. That’s okay I am more of a SNES guy.
