I know that the Wii U pro controller does not normally work in Wii mode on the Wii U but I was wondering if anyone had heard of maybe a homebrew hack or app to let you use it instead of using the wii mote and old Wii pro controller? This would be really nice to not deal with the wire anymore.
So far? Not possible. I'm not sure if it ever will be but right now you definitely can't.
