Ah, that raises a question I was curious about, are the 5 SuperGrafx HuCards in existence pretty much designed the same as a PCE/TG-16 HuCard, same number of connectors, memory design and everything? That is, the HuCard, as a memory storage format, did it stay exactly the same with the SuperGrafx and only the internal hardware was improved for the system ? I know it's backwards compatible and plays all existing HuCards as well, so I'm guessing that answers the question. In which case, I would assume the 5 SuperGrafx games using this HuFlashCard will work just fine with actual hardware. Myself, I don't really care because I don't own one and never will (I respect collectors and I think its design is real badass, but I'd never buy such a failed 5-game system - that was not a good sign of things to come for NEC).
