Games that have compatibility issues include "Sword and Sorcery" (which was released in English under the title "Lucienne's Quest"), the adult video game "Twinkle Knights" and a demo version of "Alone in the Dark". All 3DO consoles have integrated power supplies. Some models (Panasonic 3DO FZ-1, Sanyo TRY 3DO, and Goldstar 3DO) have hardwired power cords, others (Panasonic 3DO FZ-10) use an IEC 60320 C7 "figure 8" power cord. All North American model specifications are AC 120 V 60 Hz 30 W. Most 3DO systems shipped with a standard controller, as well as A/V and power cables. The 3DO controllers were unique in that the system base unit contained only one controller port and the controllers could be physically daisy chained together via a port on the back of each controller. Up to eight controllers could be linked together in this fashion. All controllers for each 3DO console are compatible with one another. In addition, standard 3DO controllers released with the Panasonic FZ-1 also contained a headphone jack and volume control for silent play. The GoldStar (LG) model also included a controller with this feature. Third party controllers were produced by a number of companies including Logitech. World International Trading Corporation also released an adapter that allows Super NES controllers to be used with the 3DO. The only light gun released for the 3DO was the Gamegun, a product of third-party developer American Laser Games. Despite this, no fewer than 10 games with light gun support were produced for the system. Most of these were arcade ports from American Laser Games (including the infamous "Mad Dog McCree"), but Virgin Interactive and Digital Pictures also released 3DO light gun games. The 3DO Gamegun uses the same design as the Gamegun released for the Sega CD: an orange "Old West" revolver. Select Gameguns house a controller port so that another Gamegun may be daisy-chained for two-player gameplay, which is supported in most of American Laser Games's 3DO titles. Though no light gun was released for the 3DO in Japan, the Japanese localizations of "Demolition Man" and "Corpse Killer" retain light gun support, and could be played by Japanese gamers using imported Gameguns. Panasonic and Logitech both released the 3DO mouse. The Panasonic FZ-JM1 and Logitech 3DO mouse are identical aside from their markings.
