# libfunctionpatcher
Requires the [FunctionPatcherModule](https://github.com/wiiu-env/FunctionPatcherModule) to be running via [WUMSLoader](https://github.com/wiiu-env/WUMSLoader).
Requires [wut](https://github.com/decaf-emu/wut) for building.

```
Replace [tag] with a tag you want to use, a list of tags can be found [here](https://hub.docker.com/r/wiiuenv/libfunctionpatcher/tags).
It's highly recommended to pin the version to the **latest date** instead of using `latest`.
