Release notes:
This is a complete re-work of my previous Atari 2600 set, which I did a couple years back. It was super messy and quite a few new dumps have been completed since then. I've hand-tested these new additions, added 57 more titles overall, upgraded a few to newer revisions, and organized the files much, much cleaner than last time.

It was a common practice for companies to "clone" games and basically duplicate them during this period, changing only a few graphics or colors and then releasing their own version. However, depending on what region or market you lived in, you may remember one game, but never heard of its clones. Cloned games, regardless of their overall changes, are included because of this. That mixed with extremely similar bits of data within titles for the 2600 may trick your emulator into thinking you have multiple copies of the same game. However, I have removed as many games as possible that were complete duplicates of each other, regardless of their names, and only one title will match one given game. If you find duplicates in the names or artwork when loading your game list, right click on each to find out what name / game ID each should really reflect.
