I do not know about Zelda or about cheats but I have been using Super Mario 64 on my Pi with Mupen64plus-GlideN64 emulator and it runs fairly well. I will say to make sure you have a powerful enough power supply. I was previously using a power supply below the recommended threshold and, while everything worked, I noticed games from systems like N64 and Playstation did not work so great. Then I started using a recommended power supply and I noticed that these games (such as Mario64) are working much better.

@herb_fargus Same. I just always ran and slid underneath it or jumped over haha.

I can get in to the castle just fine, but selecting levels, they just end up super lagging and no textures. pi3 is just not powerful enough to run it.
