Chris, I'm not joking, and I know you have better things to do with your limited time/energy, but the only thing that would have made the SuperGrafx prank even better:
A SuperGrafx sequel to Blodia (Timeball). I honestly love the game and wish there was a "100% pure adrenaline" version of the game with with gratuitous special effects (even if the effects were confined to the background art). Actually, maybe a SCD update of Blodia (that I fantasized about previously) would be just as awesome. Anyway, even if you only create mock-ups, I would be able to die happier.
