One more thing, please reply back with what main chip is in that SG. If I recall correctly, it should be the largest chip you see when you open it up. Also, note if that chip is plugged into a socket or not. I think the really early SG's had the main chip soldered tight to the board. If so, you probably will be more limited to early versions of software, which to be fair, was still miles ahead of anyone else in 1996-97 when they entered the market. If you have a socket, then it was a newer generator that could be upgraded with new chips, capable of new features.
