Is it possible to change the figuration of the classic controller for the Nintendo Wii?
The only way you can change that type of configuration is through the options menu on the games. Some games do not allow you to change which buttons do which, but for example, if you play any street figher game, you can choose which button does which. For example you can configure b to do a fierce punch, and have your y as a fierce kick. There used to be programmable controller nintendo made, but that was for the SNES and has not made any newer versions.
