Which controller for gamecube games on wii?

If I wanted to play a Gamecube game on my Wii, do I need a separate Gamecube controller? Will the classic controller work?

I dont actually think game cube games work on wii..

I have both. then again. I've never tried..

but personally I dont think it will work.
they are two completely different consols. unlike ps2 and ps3. and xbox and 360.

yes the game cube games DO in fact work on wii, however not well, its best to just use your gamecube. My friend Eric uses this feature and I think you have to use the wii controller with it

oh whoa I didnt know they worked on it.

ah oh well. im pretty occupied with 360 ;D

I've never had any problem playing GameCube games on my Wii...

But yeah, you have to use the GameCube controller.

If you want to remain wireless, go to an EB Games or a GameStop and buy a Nintendo WaveBird controller. It was the wireless controller which Nintendo made for the GameCube. Works like a champ. You can usually pick them up used for next to nothing.
