Please be advised that the following video contains vulgar language in the subtitles.
EDIT: I used the code in Project 64 version 1.6 when making this video. I'm unsure if this code will work for any emulator other than Project 64. For those of you who are having trouble adding the code in Project 64, refer to the following link: https://www.wikihow.com/Add-Cheats-to-Project-64.
In this video, you can give Mario the ability to walk on either water, lava, quicksand, or hills. Here is the code for making Mario walk on water, lava, quicksand, and hills:

Just an FYI, there was a death involved in this video that took me by pure surprise. I guess it was just my bad luck that it happened or it would be the fact that every copy of Super Mario 64 is personalized lol.
