If I was on windows I'm sure the unofficial patch would've done it all, but in linux I had to use a couple of virtualisation tools I'd never heard of (whereas every game I've tried from this decade runs out of the box with Proton). The most hair-pulling step was that I had to run the game via a symlink because if the full path to the executable was too long it'd crash to desktop before I even got to hear the menu music. God bless the protondb commenter that figured that out.
