Gamecube controller for wii?

[Coral Beef]

I have been searching a lot on this forum but can't seem to find my answer, so i thought i'd post.
I have the magicbox 3 in 1 gamecube adapter and 3 gamecube controllers, 1 wiimote and a nunchuck.
Obviously playing with the wiimote controls is not an issue, everything works fine and the game is 100%.
But i'd like to be able to play 2 player. On my REAL with with the REAL game, i'm able to plug my gamecube controller into the wii to play with a gamecube controller...
Is this supported by Dolphin? Is there anything i can do to make this work?
I have thought about using glovepie, but to be honest i find it really difficult when using an analogue signal but NOT actually inputting analogue (Because it's only emulating the keys on your keyboard, not an actual analogue stick :/).
Any of you guys had the same problem? Any suggestions/fixes?

You don't need glovpie if it works on Wii. Just configure an emulated GC pad with the inputs from the adapter.
