Speed tricks checklist:
- turn on cpu optimizations
- turn off the sound or switch it to mono via the menu
- turn off mode7 interpolation
- turn off transparencies if not needed for the game
- use 50Hz versions (EU) of your games instead of 60Hz (JP/US) for smoother but not neccessarily faster emulation (bad localization sometimes):
