Company: Konami

Konami wanted to license out Tim Burton's film adaptation of Batman for an arcade game, but were not able to as Atari Games claimed the license first.

Several of Konami's arcade beat-em-ups had a recurring feature common among other arcade games where if you wait too long to proceed to the next screen, the game will punish you for idling. In most games, such as Teenage Mutant Ninja Turtles, Teenage Mutant Ninja Turtles: Turtles in Time, Sunset Riders, Wild West C.O.W.-Boys of Moo Mesa, and Mystic Warriors: Wrath of the Ninjas to name a few, the game will take away a life in one way or another for waiting too long. However, in some other games like The Simpsons Arcade Game and Asterix, the player will only take a select amount of damage for idling, and may not necessarily be enough to lose a life.

Konami Man, one of Konami's early mascots, makes cameo appearances in several Konami games. He would later have his own game titled Konami Wai Wai World, which released in 1988, making it his first video game debut as a protagonist.

The "Moai Statues" of real-life Easter Island show up in a number of Konami-made games, the most notable examples being across the Gradius series, as well as in the Metal Gear series.

Konami formed Ultra Games in the US and and Palcom in Europe as a way of circumventing a Nintendo licensing policy which stipulated that each third-party could only release 5 titles per year for the NES. With an extra publishing arm, Konami was able to publish 10 titles per year.

Their hold on a trademark for "Ultra Games" would later prevent Nintendo from using the name "Ultra 64" for one of their consoles.

The Konami Code was created by Konami programmer Kazuhisa Hashimoto after failing to beat Gradius on the NES. He programmed a simple code into the game that gave him a full set of power-ups, which allowed him to play test the game to the end.
