The SFC EMU v1.06 source code has been released and BassAceGold has made some unofficial changes to the emulator. No official change log for version 1.06 has been released, the change log below is for the unofficial version only.
Change Log said:• Added the ability to disable or enable audio
• Added cpu speed 5 which is only slightly faster than cpu speed 4, but its there for people who may think it'll help
• Attempted to reduce freezing of entering the emulator menu from in game (haven't tested to see if it works)
