The Starpath Supercharger was an add-on module created by Starpath to expand the game capabilities of the Atari 2600. The device resembled a long game cartridge with a handle on one end. A cord coming out of the side of the cartridge plugged into the earphone jack of any standard cassette player. Games for the Supercharger were stored on normal audiocassettes.

The Supercharger interface expanded the Atari 2600's memory from 128 bytes to 6,272 bytes allowing for larger games with higher resolution graphics.
