# libgui-sdl
## Dependencies
To be able to use libgui, you need to install the following dependencies:
- [wut](https://github.com/devkitPro/wut/)
- Install the required portlibs and sdl2 via `(dkp-)pacman -Syu wiiu-portlibs wiiu-sdl2-libs`
# Credits
- Orignally based on https://github.com/dborth/libwiigui
- Wii U port / modification / new functions / sound / much more by dimok.
