Any tips

Be faster than the next guy. That usually works

PS: Welcome to the site! :)

I am new too lol Was wondering how to add a game for speedruns.

@ItzEthan I'd recommend trying a beginner speed game like super mario 64 or odyssey or playing something you've played a lot. Generally something with a highly developed route that's beginner friendly makes getting into speedrunning more fun and helps you do better with later games that you decide to run.
