Several Saturn models were produced in Japan. An updated model in a recolored light gray (officially white) was released at ¥20,000 to reduce the system's cost and raise its appeal among women and younger children. Two models were released by third parties: Hitachi released the Hi-Saturn (a smaller model equipped with a car navigation function), while JVC released the V-Saturn. Saturn controllers came in various color schemes to match different models of the console. The system also supports several accessories. A wireless controller powered by AA batteries uses infrared signal to connect. Designed to work with "Nights", the Saturn 3D Pad includes both a control pad and an analog stick for directional input. Sega also released several versions of arcade sticks as peripherals, including the Virtua Stick, the Virtua Stick Pro, the Mission Analog Stick, and the Twin Stick. Sega also created a light gun peripheral, the Virtua Gun, for shooting games such as "Virtua Cop" and "The Guardian", and the Arcade Racer, a wheel for racing games. The Play Cable allows two Saturn consoles to be connected for multiplayer gaming across two screens, while a multitap allows up to six players to play on the same console. The Saturn was designed to support up to 12 players on a single console, by using two multitaps. RAM cartridges expand the memory. Other accessories include a keyboard, mouse, floppy disk drive, and movie card.
