How to play GameCube games on a Wii
Gamecube games only work on some versions of the Wii. The original RVL-001 model from 2006 accepts Gamecube games, and has memory card slots and ports for Gamecube controllers (you still need at least one Gamecube controller and probably one or more memory cards). The RVL-101, released in 2011, removed support.
