There is a port of this game to the 3DS. Can I use that?

Ive seen people go very fast in Any% Glitchless, and ive been trying to figure this out to improve my runs. Can someone give me an in-depth explanation on how to get the most speed without glitches?

Hi! Im 14. Ive actually been speedrunning for quite a bit now, but im still just getting into it. I mainly speedrun RE:RUN, but i might speedrun some other indie games too. Ive always loved the concept of speedrunning , and im glad i get to be a part of the community.

In the rules it says no pausing, but is pausing allowed if its just a quick restart?

I was thinking of speedrunning "new" cat mario/syobon action but i see no leaderboard for the game. Any help? (Im new to speedrunning so im not sure if it matters if there is a leaderboard or not)
