simply not possible. if i remember correctly, the gamecube's cpu is on par with the wiz's. thank you exophase, the gamecube's cpu is considerably better than the wiz's. Dolphin only works on PCs because PCs have enough power to run it.
EDIT: sorry, i didn't see "what about pandora". this is the section for wiz emulation, the pandora doesn't have one yet because it hasn't been released yet. either way, the pandora cannot handle gamecube emulation either, the fastest it would get is maybe 2fps.
