I'm able to get the game to boot (overboost) but the main menu is buggy and when I get into a match it bugs out. Not sure what's wrong. Other variant of exevs2 launcher work fine
Edit 2: Retried it with exevs2, not the overboost version and it works great. If you want to get overboost working I'd use the first link in OP's post and download one of the pdf's from the post. It has a link to overboost compatible version of xboost
