In case it interest anyone. There is a mod for the classic version of the game called northerui that gives it controller support.
I have like 10-20 hours into it already and it’s worked great.
2 side notes, the game HAS to be installed in game mode and opened once before switching to desktop mode to install the mods.
Also there is another mod you need to install that helps with loading. I forget what it’s called, but it’s a really popular mod and has something to do with timestamps of files.
