To play this hack, you'll have to patch it onto your own original SM64 rom, using the included program "Flips"
Patching a rom is very simple, but if you need a tutorial, you can use this one made by kaze: https://www.youtube.com/watch?v=HUzVTZi5ws8
But if you would rather have a written tutorial:
Open the program, select "Apply Patch", select the patch file (.bps), then select your original SM64 rom, and just save the output rom somewhere on your PC.
