This unofficial Wii U emulator is an experimental piece of software that allows people to play the Wii U games they have downloaded onto their PC. As a user, you have to find a Wii U game that has been packed for unwrap on a PC. Once you have it, you may run it through the Cemu Wii U emulator and hopefully it will play.
Not every game is going to work
The Cemu Wii U emulator is an experimental and unofficial piece of software, which means it comes with no guarantees that it will actually work. Part of the process involves searching out the games on your PC, adding the files to your local hard drive, and then running them through the emulator. The games and Cemu Wii U emulator run as expected on an NVIDIA GPU and an AMD GPU, but it has heavy visual glitches when an Intel GPU is used. Controlling the game may also be difficult for some people. The DRC GamePad should work fine, as will the Pro Controller and Classic Controllers, but it doesn?t work so well with keyboard and USB controllers.
Keep your expectations low when you use it
Finding usable games is difficult, and there is no guarantee that they will work with this emulator, but the fact is that some games will work with the emulator, you simply have to find them and try them. The Cemu Wii U emulator is free to download and use, so there is little harm in trying it if you are a fan of the Wii U.
