If the Dual Analog controller is switched to analog mode while using a game which is not analog-compatible, the game will not register any button presses or, in some cases, the PlayStation will consider the controller to be detached. If a PlayStation game is DualShock or Dual Analog compatible, the player may press the Analog button located between the two analog sticks to activate the analog mode. The Dual Analog controller has three modes of operation: Digital, which disables the Analog sticks, Analog (as also found on DualShock/DualShock 2 controllers) and an Analog Flightstick mode emulating the PlayStation Analog Joystick that is not available on the DualShock or DualShock 2. The Dual Analog controller was discontinued in all three markets in 1998, to be replaced by the DualShock. This redesign eventually became the DualShock. and European models are the most commonly cited reasons that Sony decided to end production of this controller and redesign it. However, Need for Speed II, Gran Turismo, and Gran Turismo 2 feature compatibility with both NeGcon and Dual Analog control schemes.įans of a smaller form factor, Japanese players complained that the very long hand grips made the controller too large to be held properly and the lack of a rumble feature in the U.S.

Sony's Dual Analog Controller's analog mode was not compatible with the NeGcon-compatible games such as Wipeout and Ridge Racer. Namco had already released an analog controller for PlayStation called NeGcon.

A few months later, the first DualShock controller was released in Japan on 20 November 1997. It was released in the United States on 27 August 1997, and in Europe in September 1997 with little promotion. Another theory for the vibration feedback being dropped was that Sony simply wanted to keep the price of the controller down so as to maximize user adoption. Moreover, according to the United States Patent Office, two employees of Atari Games have held a patent on vibrating game controller technology since March 1991. There were rumors that Nintendo had attempted to legally block the release of the controller in North America due to the vibration feature's similarity to Nintendo's Rumble Pak, but Nintendo firmly denied that it had taken any form of legal action over Sony's controllers. According to a Sony spokesperson, 'We evaluated all the features and decided, for manufacturing reasons, that what was most important to gamers was the analog feature.' Reasons for dropping the vibration feedback reportedly included its being linked to premature malfunction of the controllers. īefore its release in the United States, Sony decided that vibration feedback would be removed from the European and American versions of the controller. It was advertised as allowing for more precise and fluid control of the games' fighters, with the rumble feature contributing to a more realistic experience. It was released in Japan in April 1997, coincident with the Japanese releases of analog-capable titles Tobal 2 and Bushido Blade. The Dual Analog Controller was first displayed under glass at the PlayStation Expo 96–97, which was held from 1 November to 4 November 1996.
