Wii U USB Helper is a free tool for easily backing up your 3DS and Wii U games. You can use the included emulators to play them on your Wii U, 3DS, or even your computer.
It’s similar to video game download clients like Steam, where you can browse the library, apply filters, and perform advanced searches.
Assume that due to some error, all of your progress is erased from the console. Even if you aren’t a pgamer, you understand the agony of losing all data.
The Wii U USB Helper requires you to specify various locations where downloaded content should be saved as well as where the app should be installed.
