 ## Building
 To build, you must first add **DEVKITPPC** and **TTYDTOOLS** to your environment. **DEVKITPPC** should be set to the `devkitPPC` folder, and **TTYDTOOLS** should be set to the `ttyd-tools` folder. Then, navigate to the root directory of the repository (the folder with the makefile in it) and run `make`. Any combination of rules can be applied to this. You should also run `make clean` after making any changes, as files built with a previous build could cause issues.
