Homebrew applications are custom, user-made software, which haven’t been authorized by Nintendo. This can include save editing tools, games, emulators, and more.
Homebrew can be run on your Wii U as long as you have a way to put files on an SD Card and your Wii U is updated to the latest version for your region.
Custom firmware (often abbreviated as "CFW") enables you to use more advanced hacks that userland homebrew can’t easily do. For instance, installing game modifications with ease.
CFW can be set up on any console on the latest version.
!> Before beginning the guide, you must know the risks of Wii U hacking: **EVERY** time you modify your system, there is always the potential for an **UNRECOVERABLE** brick. They’re rare but still a possibility so make sure you follow **ALL** directions **EXACTLY!**
> Your SD Card should preferably be 32 gigabytes large, as a full NAND backup for the console will take up around 8 or 30 gigabytes depending on your model.
If everything goes according to plan, you will lose no data and end up with everything that you started with (games, saves, NNID, etc, will be preserved).
