Real Arcade VF
From Sega Retro
Real Arcade VF is the name of two arcade sticks developed by Hori for the Sega Saturn, one a three face-button variation (HSS-09) including and , and the other a four face-button variaton (HSS-12) which adds . Both sticks were only released in Japan. The VF may suggest it was built with Virtua Fighter in mind.
The Real Arcade VF is an odd accessory as it omits many of the buttons seen in a regular Sega Saturn Control Pad. Both the Virtua Fighter and Virtua Fighter 2 arcade cabinets include three buttons, but as most Saturn games try to make use of the six standard face buttons and two shoulder buttons seen on the Saturn control pad, this makes the Real Arcade VF incompatible with the majority of Saturn titles.
Conversely, Sega's own Virtua Stick contains all of the required buttons, plus turbo switches, and is significantly easier to find. Hori's earlier accessory, the Fighting Stick SS, also includes all the required face buttons.
