As the lead coder of bsnes, I've been attempting to perfect Super Nintendo emulation for the past 15 years. We are now at a point where that goal is in sight, but there we face one last challenge: accurate cycle timing of the SNES video processors. Getting that final bit of emulation accuracy will require a community effort that I hope some of you can help with. But first, let me recap how far we've come.
Where we are
Today, SNES emulation is in a very good place. Barring unusual peripherals that are resistant to emulation (such as a light-sensor based golf club, an exercise bike, or a dial-up modem used to place real-money bets on live horse races in Japan), every officially licensed SNES title is fully playable, and no game is known to have any glaring issues.
SNES emulation has gotten so precise that I've even taken to splitting my emulator into two versions: higan, which focuses on absolute accuracy and hardware documentation; and bsnes, which focuses on performance, features, and ease-of-use.
