Absolutely - the original Wii system plays Gamecube games and can use up to 4 Gamecube controllers and 2 memory cards. You do need a Gamecube controller to play Gamecube games on the Wii.
Redesigned "Family Edition" Wiis and the Wii Mini won't run Gamecube games.
I also have "The Legend of Spyro - Dawn of the Dragons" for the Wii on Listia.
Thanks for that info. Somewhere I thought I read you would need a game cube memory card in order to keep score or save the game on a Wii sysyem. Do you know anything about that? Also, this would not work on a PlayStation 2, right?
