Ikari, the creator of the amazing SD2SNES rom cart, just released firmware 1.9.0 which primarily includes SA-1 chip support (developed by Redguy a couple of months ago), an option to go back to the menu with a short reset press, an option to start a game with or without cheats and other bug fixes & overall improvements.
By firmware 2.0.0, we might even have a complete US playable set in our hands with the addition of S-DD1 support by Magno.
