I was using the retroarch ss version...i tried all the snes9x cores and that video wave or something was happening.and I was playing ff 6 and the opening video just looked off compared to snes9x rx stand alone emulator. the vsync looked off or the anti alising something it had a wave it wasnt smooth when u seen it scroll up in the opening to it if that makes any since I play on 480p component if that matters
