That is a neat challenge idea, but I don't think it would make a good speedrun category. It just doesn't seem likely to me.
You can watch the WR time to know the order of kingdoms and what checkpoints to go to
I'm not sure if they allow it. However, I think since you aren't allowed to use everdrive, I don't think it'll be allowed. But like I said, I don't know if they do allow it or not. Unless someone comes out and confirms that you can, just stick with the actual console.
With an adapter, it should work. However, I don’t have a Wii U.
I’d assume yes, all coins. Red coins are worth 2 coins.
I’m pretty sure it’s so that everyone gets the same time. Also, you usually start a Speedrun at the beginning, not in the middle. Otherwise, anyone could start, complete one level, then start their time after they get out and hit resume. But, I’m not a moderator, so there could be some other reason
I’m just curious because in the rules it says no emulators, but when you submit a run, there’s a checkbox that says “emulator”. Can someone clarify this for me? And if it’s not allowed, why?
