Most WiiU VC injector tools already contain the patches required for this, the patches below are only needed if you do it manually.
The usage is quite simple, call WiiDRC_Init on boot and after that call WiiDRC_ScanPads every time you update your pad inputs.
To check if the gamepad is ready to use, call WiiDRC_Inited and WiiDRC_Connected, if both are true its good to go.
The analog stick range goes from about -80 to 80 so make sure to scale it to whatever you need.
The analog stick range goes from about -75 to 75 so make sure to scale it to whatever you need.
The battery status goes from 6 (full) down to 1 (critical), 0 meaning that it is currently charging.
See the "demo" folder for an example on how to use it in a bit more detail.
Both compiled Library and Demo can be grabbed from the Releases tab.
