Tengen (company)

Encyclopedia : T : TE : TEN : Tengen (company)

Tengen was a video game publisher and developer that was created by arcade game manufacturer Atari Games. After Nintendo nearly single-handedly revived the market, Atari Games realized that there was still money to be made in home video games after all. Since Atari Corp. was already involved in the home video game market with the 2600 Jr., 7800, and XEGS game consoles, Atari Games chose to create a new brand name to market their games under. They also chose to make games for the market-leading Nintendo Entertainment System rather than introduce a new home console of their own. The new subsidiary was dubbed "Tengen", which in the Japanese game Go refers to the center of the board. (The word "Atari" comes from the same game.)

Tengen unsuccessfully tried to negotiate with Nintendo for a less restrictive license (Nintendo restricted their licensees to releasing only five games per year, and required their games to be NES-exclusive for two years). Nintendo was not interested, so Tengen agreed to their standard license in December of 1987. In 1988, Tengen released their first (and only) three cartridges licensed through Nintendo - RBI Baseball, Pac-Man and Gauntlet. Meanwhile, Tengen secretly worked to bypass Nintendo's lock-out chip called 10NES that gave them control over which games were published for the NES. While numerous manufacturers managed to override this chip by zapping it with a voltage spike, Tengen engineers feared this could potentially damage NES consoles and expose them to unnecessary liability. Instead they chose to reverse engineer the chip and decipher the code required to unlock it. However, the engineers were unable to do so, and the launch date for their first batch of games was rapidly approaching.

In desperation, Tengen turned to the United States Copyright Office. Their lawyers contacted the government office to request a copy of the Nintendo lock-out program, claiming they needed it for potential litigation against Nintendo. Once obtained, they used the program to create their own chip that would unlock the NES. When Tengen launched the unlicensed versions of their games, Nintendo immediately sued Tengen for copyright and patent infringement. In the initial phases of trial, the court sided with Nintendo, but the sides settled before the matter was fully resolved.

Tengen faced another court challenge with Nintendo in 1989 in copyright controversy over Tetris. Tengen lost this suit as well and was forced to recall what was estimated to be hundreds of thousands of unsold cartridges (having sold only about 50,000). (See Tetris for more.) Later on, Tengen received the seal of approval from Sega, and they began to make games for their Game Gear and Genesis. But this wasn't enough to save them. Tengen, depleted by the costly court battles and defeats, faded into the history books by the mid 1990s. The refusal of many retailers to sell Tengen's games (due to Nintendo's threat to stop supplying any retailer that would carry Tengen's products) also contributed to the company's demise.

Tengen's unlicensed NES game cartridges do not come in the universally recognizable semi-square grey shape regular Nintendo licensed games come in, but instead are rounded and matte-black, more resembling the original Atari cartridges.
