I for sure am sold on this. Put me down for one as well!! Here is a crazy idea.. Not sure if it is even possible. is it possible to build in a sort of High Score program that saves and loads scores via a floppy disk? One floppy disk for all games kind of thing. I figure it would only work with a game that save a high score in game, such as Donkey Kong. I don't know all the implications, it sounds near impossible to me. Super cool though if accomplished. You were knowledgeable enough to create this and the prior cart, I don't under estimate your ability a bit..Figured I would throw that insanely complicated sounding option out there. Maybe a button on the cart that could grab the score from within the game and save it type of thing would work as well..
