Wii Games Are No Good On The Wii U Gamepad
The word is out; The Wii U Gamepad is not backwards compatible for Wii games. That means disc and digital games Wii titles must be played on a TV through the Wii U’s Wii mode. The Wii mode will be available day one and operates like a Wii with the console’s accessories and controls.
Even though there are no further details at the moment, Nintendo president Satoru Iwata mentioned the company’s plan to eventually incorporate a Wii U Virtual Console with full Gamepad functions.
