I'm glad to see you posted an updated version of the Enhanced Cart Adapter skaman (and BTW, congrats on being modded, that was a big surprise, and I'd say you definitely deserve it).
Though, I'm curious to ask if you got any closer to finding a way to make it and the Retrode2 able to backup/restore saves for SA-1 SNES games? If you haven't, it's not a big deal right now.
