Are there hacks for Wii games to make the gamecube controller work?

[Aussieguy]

Hi, just wondering if its possible for people to make hacks (or if they are available now) where certain Wii games only support the Nunchuku controller and nothing else, for them to be able to work with a normal controller?

I know people do hacks for many things and didnt know if this was already available now or if its possible, thanks.
