This playlists contains 119 Atari 2600 games that work with RetroAchievements. Each game has the compatible version selected and all 119 have been opened in RetroArch to confirm it was recognized as having achievements. The set I used is based off the No-Intro 20221215-125422 DAT.
Even though Big Bird's Egg Catch and Cookie Monster Munch both show as compatible, I elected to remove those from the list. Both require a custom patch to be applied before it will work. Those patches can be found on the RetroAchievements website if you can't live without them.
