Ok I have 2 questions (answered somewhere else)

1. There are 3 catagorys for speedruning on that being pc, console and legacy. I am on pc however I am using the windows store (xbox gamepass) version of the game. Would a speedrun from here need to goto pc or console?

2. I have noticed in game rules it states you have to use a brand new save. On pc on glitchless speedrun is this required? 2.5. How would I preform a clean save on the windows version?
