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
Thanks for the lengthy explanation, sounds interesting. Is the thumb button for ducking or jumping?
Usually, thumb is for jumping, but some people prefer the other way.
