Drivechips are used to inject code into the Panasonic MN10200-based microcontroller in the disc drive. The firmware on this chip is stored in mask ROM, but is loaded into RAM before execution; these chips use debug commands to patch the firmware in RAM upon boot, generally to defeat the protection against recordable DVD media.

These chips are most commonly used for piracy, but they did also play an important role in the early stages of Wii homebrew development. A drivechip can be used to run GameCube homebrew on the Wii, as well as trucha signed Wii homebrew.
