Using gamecube controllers with Wii games?

[greenhorn1]

Reading the PCmag review of the wii I noticed that they said you can NOT use the gamecube controllers on wii games. I was under the impression that this was possible (specifcally on metal slug). Does anyone know if it's determined by game or if I was just mistaken?

From what i've read, it can be used for gamecube only.. possibly virtual console. We'll find out this weekend!
