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
I don't have videos yet, but I'll post something soon!
It feels awesome. The action buttons have a great feel that's between clicky and mushy and they don't make a ton of noise when I mash them.
This was my first experience with a Korean lever. The stick actuator pushes on a silicone grommet which pushes the four directional switches. The result is it feels like the gate is a big circle while I still hear a click confirming when I press or release a direction. I find this makes special move inputs easier. The caveats are you need an adapter for the cables to work with a Japanese style stick, (which I bought with my joystick for an extra buck) and you need a 35mm hole for the "collar" and horizontal holes drilled in the mounting plate to accomodate. Fortunately Eternal Rival took care of all of that when I put my order for the kit together.
Here's the build manual from Eternal Rival which should explain how it all goes together
