Re: Hey The Dumper(TxT

This is about the coolest Genesis cart ever. My sources tell me (OK, web search) that this was used by Blockbuster to load games on for rental.

It looks like your cart doesn't have a game loaded in it. Your cart appears to be a 16Mbit flash cart (2 x 8Mb flash chips) upgradeable to 32Mbit by adding two more chips on the back (notice the difference in the part #'s, one is probably a reverse pinout).

More good news, since there is no ASIC on it, it probably uses a fairly simple signal select for programming so you might be able to figure out how to program games into it.

If you spot any more of these carts let me know. I'll try to pick one up and play around with it.

The edge connector connection seem to be supposed to go in some IC labeled SP720AP, but those chip aren't there. Those chips seem to have been hand-removed, this is why I wanted to check if there was any game hided on the cart, but I guess it has nothing on it. Very weird cart indeed.

When I insert it in a genesis unit, nothing come up, so the cart must be empty, but when I opened it, I found out that there is no pins from the cart connector that go anywhere except for the ground if I remember well. I have some Hi-Res pic of the gut of the cart if you are interested in it.
