Arcade Power Stick
From Sega Retro
There are two versions of the Arcade Power Stick, one with three face buttons and one with six. Both sticks come equipped with turbo features, which whose speed can be configured. The six button version of the controller was called the 6 Button Arcade Stick in North America, Arcade Power Stick II in Europe and Arcade Power Stick 6B in Japan. A version by S-Chi was also released.
The Japanese release of both the Arcade Power Stick and the Arcade Power Stick 6B feature joysticks with microswitch input, akin to arcade hardware. All non-Japanese versions of the peripheral utilize joysticks with rubber contacts, similarly to the D-pad of a standard controller. All releases regardless of region use face buttons with rubber contacts, identical in function to that of a standard controller.
