Nice one! DSP games work fine via fullpath as long the DSP bin files are within the snes.zip and snespal.zip files, perfect! As for the performance hit, I've got Mario Kart running at 100%, but only just, it runs at 108% unthrottled. It's REALLY nice to see all CPUs running within snes and snespal. Any news on how Super Gameboy games will work? Via a second slot maybe?
