Also make sure to install [wut](https://github.com/decaf-emu/wut), [WiiUPluginSystem](https://github.com/wiiu-env/WiiUPluginSystem) and the [WiiUModuleSystem](https://github.com/wiiu-env/WiiUModuleSystem).
|
||||
It requires the [KernelModule](https://github.com/wiiu-env/KernelModule) to be running at the same time and it's linking aginst [libkernel](https://github.com/wiiu-env/libkernel).
