Wii Punch Out to Support Balance Board

Balance Board support has been added to Wii Punch-Out so now there are 3 ways to play the game. You can play it the classic way with the Wii-mote turned sideways just like a NES controller, another way to play is with the Wii-mote and Nunchuk combination and now you can also play with the Wii Balance Board most likely using the Wii-mote and nunchuk together.
