I built a fightstick the other week! Mostly for Street Fighter 6, though I have played some other 2D games including Hades and River City Girls with it as well.

Parts:

-Brook UFB Fusion board for compatibility with PS4/5, XBOX 360 and above, Switch, Wii U, PC and more

-Crown 309 Helpme K ST35 lever

-Qanba Gravity KS buttons for the top and Seimitsu standard for the sides

-Custom enclosure kit from Eternal Rival
