Hello, I have been learning to speedrun undertale genocide route on my switch, however the input delay is very annoying. I do have a steam deck, but I know that you need to disconnect undertale from steam, add files to the undertale folder, all that stuff. but i do not know how to set this up on steam deck. is there anything i need to do beyond just changing the version on linux, and how do I disconnect UT from steam? (the steam deck is my only gaming pc)
