Since I'm not finding context, I think this is the gist:<p>OoT modders programmed custom stuff into the game by using arbitrary code execution exploits, to create content that is generally considered to be "rumored" in the game, but also obviously modern stuff like BoTW demake cutscenes and Twitch messages.<p>EDIT: actually, I think the demonstration starts by showing off legit "hidden feature" stuff existing in the original OoT game (enabling a debug mode), but quickly gets creative.<p>This is _not_ a speedrun of an actual beta version of OoT (it's far more interesting).<p>For more: <a href="https://www.youtube.com/watch?v=qBK1sq1BQ2Q" rel="nofollow">https://www.youtube.com/watch?v=qBK1sq1BQ2Q</a>
