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
My primary aim was to make the size as small as possible with full size arcade buttons.
But wait, there's more.
. I usually play on the Steam Deck (which only has one USB port) and this way I can plug a charger or second controller into the side of my hitbox, or even wired headphones.
