were canceled. The only peripherals and add-ons released by Atari for the Jaguar are a redesigned controller, an adapter for four players, a CD console add-on, and a link cable for local area network (LAN) gaming. The redesigned second controller, the ProController by Atari, added three more face buttons and two triggers. It was created in response to the criticism of the original controller, said to lack enough buttons for fighting games in particular. Sold independently, however, it was never bundled with the system. The Team Tap multitap adds 4-controller support, compatible only with the optionally bundled White Men Can't Jump and NBA Jam Tournament Edition. Eight player gameplay with two Team Taps is possible but unsupported by those games. For LAN multiplayer support, the Jaglink Interface links two Jaguar consoles through a modular extension and a UTP phone cable. It is compatible with three games: AirCars, BattleSphere, and Doom. In 1994 at the CES, Atari announced that it had partnered with Phylon, Inc. to create the Jaguar Voice/Data Communicator. The unit was delayed and an estimated 100 units were produced, but eventually in 1995 mass production was canceled. The Jaguar Voice Modem or JVM utilizes a 19.9 kbit/s dial up modem to answer incoming phone calls and store up to 18 phone numbers. Players directly dial each other for online play, only compatible with Ultra Vortek which initializes the modem by entering 911 on the key pad at startup. Jaguar CD The Jaguar CD is a CD-ROM peripheral for games. It was released in September 1995, two years after the Jaguar's launch. Thirteen CD games were released during its manufacturing lifetime, with more being made later by homebrew developers. Each Jaguar CD unit has a Virtual Light Machine, which displays light patterns corresponding to music, if the user inserts an audio CD into the console. It was developed by Jeff Minter, after experimenting with graphics during the development of Tempest 2000. The program was deemed a spiritual successor to the Atari Video Music, a visualizer released in 1976. The Memory Track is a cartridge accessory for the Jaguar CD, providing Jaguar CD games with 128 K EEPROM for persistent storage of data such as preferences and saved games. The Atari Jaguar Duo (codenamed Jaguar III) was a proposal to integrate the Jaguar CD to make a new console, a concept similar to the TurboDuo and Genesis CDX. A prototype,
