Can The Wii U Play Gamecube Games? Share on Facebook Tweet on Twitter 55 viewsJuly 6, 2019HardwareBackwards Compatibility 0 NukeZer0473 November 18, 2017 Even though the Wii used big discs, it still allowed you to insert a smaller gamecube disc and play it. Does the WiiU also let you play gamecube games? 1 Answer ActiveVotedNewestOldest 0 Dan Hastings1.89K Posted November 18, 2017 0 Comments The Wii U completely emulates the Wii. You literally load up the full Wii operating system inside the Wii U. This makes it possible to use GameCube discs with the Wii U. The disc drive will support the disc size just fine.
