Developer: Ed Federmeyer

Ed Federmeyer is a hobbyist programmer who wrote Sound X in the mid-1990s, after Atari had stopped selling the 2600. It is not a game but a cartridge for exploring what the console’s sound chip can do, and it is one of the earliest 2600 homebrews. Federmeyer described this kind of hobby work as “homebrew”, a name borrowed from the Homebrew Computer Club, and the word stuck. His next project was Edtris, an unlicensed Tetris.
