How to use gamecube controller on Wii games?

[121derp121]

So I have and use the official WiiU gamecube controller adapter. For Gamecube Controllers, I have Port 1 set to "Gamecube Adapter for Wii U", and it works for Gamecube games. For Wiimote, however, all there is is None, Emulated Wiimote, Real Wiimote, and Hybrid Wiimote. And when I choose one of those that I can actually configure (Emulated or Hybrid) and try to choose the adapter under device the adapter is not there. 
     
   
How do I make it so I can use the gamecube controller for Wii games, if possible?

If the game works with gamecube controllers, the game should work just like it does with gamecube. If you want to use the gamecube controller as a wii remote, you will have to install separate drivers to work as a generic controller.

Where can I get those drivers?
