The following is a complete list of companies that produced games for the Atari 2600. Most of these companies are long out of business. But a few moved on to other things and managed to survive. One company Hozer Video Games still makes new Atari games.
Under each one of these companies you will find a complete list of games that they produced. This node used to host a large gamelist, (but it was just to big for one node).
If you are looking to node an Atari game, this is the place to start. Companies in bold have already had all of their games noded.
Please send me a /msg if you node an
Atari game. So I can consider it for a C!.
