It’s like a 6-button gamepad. Think like.. the Sega Genesis 6-button controllers with two additional triggers at the top.
Or…
360 controller featuring Ken.
PS3 controller featuring Akuma.
There’s 5 different graphics for both systems. Akuma, Ken, Chun-Li, Ryu, and Blanka.
Granted, there are also actual arcade fighting sticks, starting out at $80 a pop. That’s assuming you can find it in a store.
