save data or state from GC to wii?

[AnyOldName3]

I know that the only way a real wii can handle gamecube data without being hacked is via gamecube memory cards, so if you mean a real wii then you'll need to put a memory card containing the data in the top. If you want to resume it on dolphin, then there may or may not be a way to make the save data compatible.
