18 minutes
I've made some contributions to the ALttP Randomizer wiki over the years. Its overall organization is a mess, and I improved some important things about it, while making new messes by starting pages that I didn't finish
but the thing I'm proudest of adding to the wiki is the page called "18 minutes".
In Twitch and Discord chats, it would keep coming up that if you do various glitches incorrectly it might freeze your game, and someone would chime in with the fun fact that the game might actually unfreeze if you wait for 18 minutes, and then people would want to know why it works like that and why this 18-minute timer keeps coming up in seemingly unrelated contexts.
So I made the page, and now if we're writing a wiki page about a glitch, we can just put a link around the text "18 minutes" and then it's explained.
In short: if you do a glitch with the wrong setup, you may have to wait for a counter initialized to the wrong value to reach the right value. It may have to count for up to 65535 frames, which is about 18 minutes.
