Wii U:Dump Games

For support (in English) with dumping Wii U discs, join Nintendo Homebrew on Discord.

It is ILLEGAL to share the files dumped with this guide. If you intend to use this guide to share your dumped games, don’t.

Dumping and Installing Wii U Discs

Installing a game to the system memory (NAND) is not recommended as it’s limited to either 8GB or 32GB depending on your model, making you run out of space pretty quickly if you want to install multiple games.

If you do not have enough space on your SD Card, you can use an advanced technique to install dumps from a USB device. This is not the easiest thing to do and has the disadvantage of only being able to install the game onto your system memory (NAND).

In order to install to a USB device, it has to be formatted by the Wii U. Doing this will erase all contents of it, and prevent it from being used on another system unless you reformat it. To do this, plug your USB HDD into the Wii U, power on your Wii U, your Wii U will prompt you to format your HDD. Confirm with Yes.
