There are 3 loading zones in the castle, 1: The Lobby and all single doors and star door. 2: The basement with all rooms in the basement plus the star door 3: The Staircase + All upstairs.

You can't clip between loading zones. You will have to get the keys first to get access to the loading zones

Are there really people who do that? Isn't that against the terms of service from Speedrun.com?

You can stream your xbox gameplay to your Windows 10 PC (Via the XBOX app), then you can record that screen and it should work, If you already have a laptop with a webcam and a decent internet connection, you will all be fine

Send me a PM If you need help setting it up

I looked in the rules of the 100% category, it states what has to be shown on the run: "The initial load of the game, because not everything is reset correctly when starting a new game from in-game."

-I think it has something to do with certain things that save and are not reset properly, for example CJ’s Stats

-Could also have something to do with RNG (Random Number generation) to make it as fair as possible
