-# Super Mario 64 Enhancements
-
-This directory contains unofficial patches to the source code that provide various features
-and enhancements.
-
-To apply a patch, run `tools/apply_patch.sh [patch]` where `[patch]` is the name of the
-.patch file you wish to apply. This will perform all of the patch's changes
-to the source code.
-
-Likewise, to undo the changes from a patch you applied, run
-`tools/revert_patch.sh` with the name of the .patch file you wish to undo. 
-
-To create your own enhancement patch, switch to the `nightly` Git
-branch, make your changes to the code (but do not commit), then run `tools/create_patch.sh`.
-Your changes will be stored in the .patch file you specify.
-
-The following enhancements are included in this directory:
-
-## 60 FPS - `60fps_ex.patch`
-
-This allows the game to be rendered at 60 FPS instead of 30 FPS by interpolation (game logic still runs at 30 FPS).
-
-The Mario head intro is the only exception which is still rendered at 30 FPS.
-
-This is the 60fps patch from [sm64-port](https://github.com/sm64-port/sm64-port/tree/master/enhancements) adapted for sm64ex.
