BC (short for Backwards Compatibility) is a bootloader similar to boot1 that is responsible for verifying and loading boot2 in a state that will make it load MIOS. It is run when a GameCube game is launched from the Disc Channel. It is unknown why Nintendo did not simply place all of the GameCube compatibility code in MIOS.
