This has been bugging me since nintendont started being able to use the gamecube adapter. I understand that this doesn't mean that you can just copy paste that code to work with Wii games. However, I'd think that it would be possible to inject a code that would work similar to how rockband on wii interpreted the input of the guitars/drums, but be tweaked to interpret the GC adapter. Or at least something along those lines. I might be seeing hope where there isn't any, but with all the crazy hacks I've seen for the Wii I feel hopeful that it's possible.
