In what is likely the most ingenious concept of Wii U’s lifespan, Hyperkin is currently testing a GameCube-esque Wii U wireless controller that will be fully compatible with Wii U Pro Controller titles. Not to be done by some of the other third-party controller announcements this week, the new controller titled “ProCube” showed up in a reddit post on /r/SmashBros early yesterday. Unlike Nintendo’s proprietary Wii U GameCube controllers, the ProCube is able to sync via the same method as a Wiimote or Wii U Pro Controller, making the “Wii U GameCube Adapter” completely unnecessary. Even more interesting, the controller (utilizing an additional few buttons) is fully compatible with any of the 130+ Wii U Pro Controller titles, meaning you can use this modified GameCube controller with games such as Mario Kart 8, Bayonetta 2, Xenoblade Chronicles X, or The Legend of Zelda: Wind Waker.
The ProCube is still in its prototype stages, however Hyperkin hopes to have it at EVO 2015 to get player feedback. The current price expected is somewhere between $30-40, with no definite release date.
