I've really liked hitbox controllers for Street Fighter 6. I've been really happy with how they've turned out and they're a joy to use. If there's interest I can post the build process/instructions/guide.
Also would be good to grow the community if you're interested: !arcadesticks@lemmy.world
Is "up" in between left and right, or is it the thumb button? Do people have different preferences with that?
People have different preferences but generally, "up" is the thumb button.
