The Wii features backward compatibility with its predecessor, the GameCube, having the ability to run its discs and use its controllers and memory cards. Later versions of the system from 2011 onwards removed the controller and memory card slots which effectively removed this ability, however the motherboard still has the pads for them and can be soldered back in with modification.
