Atari 7800/Homebrew

The 7800 was a flop in the market place, due to when it came out and the competition. Regardless, the fan community has still kept the system alive with a number of homebrew titles. Most of the games below were done by homebrew programmer superstar Bob DeCrescenzo, aka PacManPlus.

Some of these can be purchased with PokeyOne chips for enhanced sound.

All these can be bought from Atariage. Here's a huge list of other homebrews and hacks with ROMs.
