I also have a bunch of Atari 2600 games I can't play because I lack the system's adapter cord, and I may have some other old games lying around, as well, but I'm not sure as many of them were stolen a few years ago and I'm just copying these titles from a list I've already got.

For a more comprehensive list of my entire gaming history, go here.
