why do 100% runs go to the sub area in cascade instead of the rocket moon sub area in bowser's? i thought that was faster

I need a capture card that can record on a Switch without the use of a computer, just standalone recording because i cant use a computer. I found one, but its like 120 and i need a cheaper option.

I speedrun this game at a mediocre pace, and I would like to know which browser version is the best, like which has the most glitches available and least lag.

I used to have access to an auto restart that would allow you to bind a key to instantly restart the run. However, my game updated which got rid of it, and I cannot find it anywhere. I also see recent runs still using it. How can I get it?
