My kids love to play Gamecube games on the Wii, that is one system they never got. If you have a Ross near you, sometimes they have Gamecube controllers really cheap. They are about $8 for corded and $13 for wireless. Usually near the mens department with the headphones, etc. Also, you need to know if they are playing Gamecube games on the Wii you need a Gamecube memory card. The Wii one does not save it.
