Wii U and Wii fans who always wanted to play their games with the (superior) Switch Pro Controller or relax on the couch with the Joy-Cons (like myself) can now do so after a recent firmware update for the Titan Two, a device that brings cross-over controller support to various game consoles. PS4, PS3, Xbox360 and Xbone controllers are also supported. After the firmware update, a new output protocol option will appear from a drop-down menu in GTunerIV.
After selecting this option, you can pair your controllers wirelessly with the Titan Two, edit the button configuration (if needed) or load up some scripts. Your Wii/Wii U will recognize the Titan Two as an official controller and you're good to go.
