They pop up sometimes, I could let you know what one comes up on an auction or something.

Also, I have one, I could sell it for the right price of course.

About your question about copying a game... that depends. Do you want it on a proto board or a sacrificed normal cart (arguably this is harder)? I could maybe do the first one for you, I have some empty carts around, but my service would be way overpriced, since I have no time for anything, so you might want to find someone else. Also I'd have to mark your cart with something visible so you wouldn't sell it as a real cart later or something :P
