It says it works for real Wii U. how do I install or use it?

Hey, I have a WiiU so i guess I can help.

Firstly, you will need a single-board computer; the README recommends the Raspberry Pi Zero W or the Raspberry Pi 4 B.
But they have gotten pretty expensive due to AI companies ordering RAM and stuff.
I guess you do not have one lying around, do you?

That sucks, and emulators are not an option for you?

Cemu is a Wii U emulator, https://cemu.info/

You can use this to connect your Wii U Pro Controller to your Pc If you have one: https://github.com/KeyPuncher/WiinUPro
