I came across this huge database of Atari 2600 games. There is over 8000 games, but, what is fascinating is that the site member, Rom Hunter, has put together a collection of 3000 games in one zip file. Rom Hunter writes
Now, after almost ten years of collecting and researching, the result of all this work can be downloaded below. I’m very proud to present you my personal Atari 2600 ROM collection here on Atarimania and I truly hope you will enjoy it as much as I do.
short: if you’re looking for an ordinary Atari 2600 ROM set, look elsewhere. It can be found almost everywhere on the Internet without too many problems. If you’re looking for the most genuine and best documented Atari 2600 ROM collection in the world, then look no further: this is the place to be.
I managed to download the collection and am playing the games, at least some of them, via Stella emulator on Linux
