I've been told this is a lot like asking 2600 users if they need Pac-Man. Still, I suppose it doesn't hurt to ask. I bought my son a whole box full of 2600 games for the console I gave him, and lo and behold, there was one 7800 game in the box--Pole Position II. The label is a bit rough, and since I don't have a 7800, I have no way to test it. If you've got any 2600 or 5200 games you'd like to trade for it, let me know. I figured I'd try an even swap with an AtariAge user before I put it up on ebay.
Happy Gaming, folks!
