Virtua Stick Pro
From Sega Retro
The Virtua Stick Pro is an arcade stick peripheral for the Sega Saturn. It can be seen as an "upgrade" to the regular Virtua Stick (second version), having the same aesthetics and shape but being twice as long to accomodate a second player. It was only sold in Japan.
The Virtua Stick Pro is unique in that it can be customised depending on which fighting game you are playing. There is a section at the top of the unit where one can slide in instruction overlays to give a more "arcade" feel.
