Atari 2600 homebrew is a term describing hobbyist-developed games for the Atari 2600 video game console. The first such game was written in 1995, and more than 100 have been released since then. The majority of games are unlicensed clones of games for other platforms, and many were written for the technical challenge. There are also ROM hacks and some original games. Several games have received attention outside the hobbyist community. Some have been included in a game anthology by Activision.
