I used both these games for tournaments at the museum so they were gone through by me, to be sure that everything worked perfectly at that time but who knows at this point, it's been a couple years at least. The Butterfly, like most Sonic's, is really nice. Same for Combat. It's in nice shape and played well or I wouldn't have bothered with it. A friend of mine actually pulled this out of a garage in Huntington Beach and sold it to the museum.
