Wii U Virtual Console features fully customizable controls
By tapping the touch screen (ZL+ZR also worked), you can access the Virtual Console menu, which allows you to create a restore point, reset the game, or change controls. From there, you can alter the individual button mapping for any controller you have plugged in: I tried a GamePad, Wiimote, Wii U Pro Controller, and Wii Classic Controller, and each let me set the function of every button on the device. The GamePad, Wiimote, and Classic Controller all served as the player 1 controls, and the Pro Controller defaulted to player 2.
I hastily snapped photos of all the menus, which you can see in our gallery to find out just what 30 cents gets you.%Gallery-177046%
