Wii U Cafe SDK Deluxe is a tool to facilitate the creation of an installable image of a Unity game on a retail Wii U and not a CAT-DEV or CAT-R which are official development kits.
To use this tool, you need several things: A Retail Wii U, Unity For Wii U and the Cafe SDK.
Note : This tool can also be used without Unity. If you develop an homebrew you can use this tool (with some modifications in your folders) and easily make a installable version for your Wii U.
The v2 of Wii U Cafe SDK Deluxe will integrate a lot of changes in the Back of the tool. A support for Splash images will be added. The development of the v2 will start when I will have extra times from my other personal projects
I am currently writing in French and English a complete tutorial for my tool and how to make a Game with Unity Wii U. But I write an short tutorial about how to use this tool on GBATemp. Check it here
To build from source Wii U Cafe SDK Deluxe, you will need .Net Framework 4.8 and Visual Studio 2022 for Windows.
