I got three prototype SNES boards, Taz, Blackthorne, and Football Fury, that don't work. I tried them on both a mini and regular SNES system. I don't have the technical chops or equipment to dump them and see if the data is sound on any or all of them.
Does anyone (with an established track record on NA) want to try to dump these? I will be at CGE if anyone is bring equipment there. Otherwise, I can mail them to you, but you have to mail them back to me. I don't mind if you dump, compare and distribute the contents.
