Tengen Inc. was an American video game publisher and developer that was created by the arcade game manufacturer Atari Games for publishing computer and console games . It had a Japanese subsidiary named Tengen Ltd. ( 株式会社テンゲン , Kabushiki-gaisha Tengen ) .

51-460: A voltage spike , Tengen engineers feared this could potentially damage NES consoles and expose them to unnecessary liability, and so they started development on a chip they called Rabbit. The other problem was that Nintendo made frequent modifications to the NES to prevent this technique from working. Instead, Tengen chose to reverse engineer the chip and decipher the code required to unlock it. However,
68-447: A constant current will flow. Current from a discharging inductor is one example. For sensitive electronics , excessive current can flow if this voltage spike exceeds a material's breakdown voltage, or if it causes avalanche breakdown . In semiconductor junctions , excessive electric current may destroy or severely weaken that device. An avalanche diode , transient voltage suppression diode , varistor , overvoltage crowbar , or
85-580: A controlling stake in Atari Games, Tengen was consolidated into Time Warner Interactive . In 2024, homebrew developer Jeff Silvers acquired the "Tengen" trademark to launch a new company called Tengen Games. The company's first game was Zed and Zee , an 8-bit arcade-style action platformer for NES, Famicom, and Windows. Tengen manufactured both licensed and unlicensed versions of three of their NES games ( R.B.I. Baseball , Gauntlet , and Pac-Man ). The cartridges for their unlicensed games did not come in
102-704: A less restrictive license to produce games for the Nintendo Entertainment System ; Nintendo refused, so in December 1987, Atari Games agreed to Nintendo's standard licensing terms. Tengen was incorporated on December 21 of that year. In 1988, Tengen released its first and only three games licensed by Nintendo: R.B.I. Baseball , Pac-Man , and Gauntlet . Meanwhile, Tengen secretly worked to bypass Nintendo's lock-out chip called 10NES that prevented unlicensed NES games from running. While numerous manufacturers managed to override this chip by zapping it with
119-549: A localized Sega CD title. The company also licensed games for home computers such as the Amiga and the Atari ST , most of which were published by British company Domark . It was best known for its ports of popular Atari arcade games, including Klax , Hard Drivin' , STUN Runner , and Paperboy , although they published many other titles as well. In 1994, with the lawsuit against Nintendo settled, and after Time Warner re-acquired
136-483: A range of other overvoltage protective devices can divert ( shunt ) this transient current thereby minimizing voltage. Voltage spikes, also known as surges, may be created by a rapid buildup or decay of a magnetic field, which may induce energy into the associated circuit. However voltage spikes can also have more mundane causes such as a fault in a transformer or higher-voltage (primary circuit) power wires falling onto lower-voltage (secondary circuit) power wires as
153-577: A result of accident or storm damage. Voltage spikes may be longitudinal (common) mode or metallic (normal or differential) mode. Some equipment damage from surges and spikes can be prevented by use of surge protection equipment. Each type of spike requires selective use of protective equipment. For example, a common mode voltage spike may not even be detected by a protector installed for normal mode transients. Power increases or decreases which last multiple cycles are called swells or sags, respectively. An uninterrupted voltage increase that lasts more than
170-545: The electric potential of a circuit are typically caused by In the design of critical infrastructure and military hardware, one concern is of pulses produced by nuclear explosions , whose nuclear electromagnetic pulses distribute large energies in frequencies from 1 kHz into the gigahertz range through the atmosphere. The effect of a voltage spike is to produce a corresponding increase in current ( current spike ). However some voltage spikes may be created by current sources. Voltage would increase as necessary so that
187-417: The NES. Tengen announced that they were going to release their own cartridges in December 1988. When Tengen launched the unlicensed versions of its games, Nintendo immediately sued Tengen for copyright and patent infringement. This began a series of lawsuits between the companies which would not be settled until 1994. Tengen faced another court challenge with Nintendo in 1989 in copyright controversy over

#1732855774468204-566: The engineers were unable to do so, and the launch date for its first batch of games was rapidly approaching. With time running short, Tengen turned to the United States Copyright Office . Its lawyers contacted the government office to request a copy of the Nintendo lock-out program, claiming that the company needed it for potential litigation against Nintendo. Once obtained, it used the program to create its own chip that would unlock
221-452: The gray, semi-square shape that licensed NES games came in; instead, they are rounded and matte-black, and resemble the original Atari cartridges. Voltage spike In electrical engineering , spikes are fast, short duration electrical transients in voltage ( voltage spikes ), current ( current spikes ), or transferred energy ( energy spikes ) in an electrical circuit. Fast, short duration electrical transients ( overvoltages ) in

255-462: The two companies' NES versions of Tetris . Tengen lost this suit as well, and was forced to recall what was estimated to be hundreds and thousands of unsold cartridges of its version of Tetris (having sold only about 50,000 copies). Tengen went on to produce games for other systems, including the Sega Genesis , Master System , Game Gear , and TurboGrafx-16 , and a few more, as well as publish
272-409: Was dubbed Tengen , which in the Japanese nomenclature of the board game Go refers to the central point of the board (the word "Atari" comes from the same game). At the time, Nintendo restricted their licensees to releasing only five games per year, mandated that Nintendo handle cartridge manufacturing, and required their games to be NES-exclusive for two years. Atari Games tried to negotiate for
289-462: Was responsible for computer and console games and hardware and owned the rights to the Atari brand for these domains. Atari Games was formed from Atari, Inc.'s arcade division, and were able to use the Atari name on arcade releases but not on console or computer games. When Atari Games wanted to enter the console game market, it needed to create a new label that did not use the Atari name. The new subsidiary
