Unfortunately New Super Mario for the Wii needs to the motion controller at times. I was shocked when my classic controller didn't work with it, allthought once I realized it needed motion I understood why.
At least this controller has the cable coming out of the top. I find on the classic controller, it coming out of the bottom is a pain.
I'm hoping this will be backwards compatible with any of the other games that can use the classic controller like mario kart wii?
