Homebrew Atari VCS/2600 Arcade Ports

The long-running Atari fansite AtariAge sells a number of carts that run on classic Atari VCS systems that make it do things you might not expect that system could do.

Here are links to a number of videos showing them off, although sone of the may not currently be in their store:
