You can load a backup version of your legally owned copy of melee from the wii mode of your wii u. While you are playing said backup, the wii u recognizes the wii u pro controller as a classic controller, and it works great. The advantage of this is getting almost no input lag through an hdtv while playing melee which has never been possible before. Due to the wii u's hdmi connection the lag is significantly reduced. I don't know if I'm allowed to post links here thoughHow are you playing Melee on the Wii U?
