Hi, atari.io thanks for adding me as a member! I just wanted to share some of the homebrew games I've been working on for Atari 2600 - all available for free here:
http://atari.metalbabble.com/
They should play properly on real hardware or in the Stella emulator. Let me know if you have any questions!
I can't wait to check out the site further and play the other homebrews here. Thanks!
