### Homebrew
|
|
|
|
|
|
> Homebrew applications are custom, user-made software, which haven’t been authorised 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
|
|
|
|
|
|
> Custom Firmware (“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.
|
|
|
|
|
|
### Uses of Homebrew and CFW
|
|
|
> Among other things, it allows you to do the following:
|
|
|
> * Use “ROM hacks” for games that you own
|
|
|
> * Backup, edit, and restore saves for many games
|
|
|
> * Play games for older systems with various emulators, using RetroArch or other standalone emulators
|
|
|
> * Play out-of-region games
|
|
|
> * Dump your Wii U game discs to a format that can be installed on your internal or external Wii U storage drive.
|

### End Goal
|
|
|
|
|
|
> This guide has the end goal of taking a completely unmodified Wii U from Stock to Custom Firmware.
|
|
|
|
|
|
### Before Starting
|
|
|
|
|
|
!> 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.
|
|
|
>
|
|
|
> This guide will work on all Wii U consoles in all regions on firmware 5.5.4 or below.
|
|
|
>
|
|
|
> You will need the following in order to successfully follow this guide:
|
|
|
>
|
|
|
> - An SD Card
|
|
|
> - A device such as a Computer to place files onto the SD Card
|
|
|
> - A Wii U with internet access
|
|
|
>
|
|
|
> 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, NNID, saves, etc will be preserved).
|
|
|
|
|
|
Keep your device plugged in throughout the entire process to avoid data loss or damage from an unexpected power-off.
|
|
|
|
|
|
Custom Firmware is not permanent with current methods, and will be unloaded upon rebooting the system.
|
|
|
|
|
|
It is advised that you read the entire guide from start to finish one or more times before actually running through the guide with your system.
