If you've played OOT64 before, I highly recommend watching the original twitch video (linked above by clarkrinker) before reading the theclick.gg article or watching any of the explainer YouTube videos, for the experience of seeing the beta content revealed in real-time.

If you've seen any video game glitch videos with arbitrary code execution before, you can probably skip ahead to 13:07:30 if you want to save 10 minutes, past the intro and glitch setup where they're giving some basic background about how it works.

After watching the video, in addition to the explanation videos that others have linked, you can check out this official FAQ from the showcase creators: https://gettriforce.link/faq

Thanks! I was trying to look for a video link in the article. I also recommend this year's Celeste and Lumione speedruns (which I sadly don't have a timestamp for, but I think both are in this same twitch video).

Ends at 13hr 55min. Worth it if you have an hour to burn!
