Sorry for the noob question, but I can't figure this out myself. How do I use a controller hack for DKCR that allows me to use the Classic Controller?

My Wii is softmodded as per the guide over at http://www.wiihacks.com/recommended-...d-any-wii.html. Now, I've read about people using "Ocarina" and some codes, but I'm really uncertain about what that all entails and what Ocarina even is. Can anyone help me?
