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

This is the only community I could find, but it only has 7 users and is pretty dead.
