Donkey Kong (game)

Donkey Kong is an arcade game that was Nintendo's first big hit in North America. It marked the beginning of the Mario and Donkey Kong franchises and introduced several of their earliest characters, including Mario himself (a carpenter rather than a plumber), the original Donkey Kong (who, in later games, would become Cranky Kong, the current Donkey Kong's grandfather ), and Lady (later renamed Pauline). A version of the game was also created later for the Nintendo Entertainment System, Nintendo's first home console, under the Arcade Classics Series. The game sold very well in the United States, becoming one of four games to be inducted into the Nintendo Hall of Fame. The original arcade version had four screen levels, but the Nintendo Entertainment System version only has three, with the stage 50 m cut. This game was also the first title to be released on Virtual Console. Donkey Kong was the second platforming game ever made; the 1980 game  was the first.

Story
Donkey Kong has kidnapped the beautiful Lady and taken her to a dangerous construction site. Mario must climb to the top of the construction site and rescue Lady from the giant ape.

Official story quoted from Nintendo of America
"HELP! HELP!" cries the beautiful maiden as she is dragged up a labyrinth of structural beams by the ominous Donkey Kong. "SNORT. SNORT." Foreboding music warns of the eventual doom that awaits the poor girl, lest she somehow be miraculously rescued. "But wait! Fear not, fair maiden. Little Mario, the carpenter, is in hot pursuit of you this very moment." Throwing fate to the wind, risking life and limb, or worse, little Mario tries desperately to climb the mighty fortress of steel, to save the lovely lady from the evil Mr. Kong. Little Mario must dodge all manner of obstacles- fireballs, plummeting beams and a barrage of exploding barrels fired at him by Donkey Kong. Amidst the beautiful girl's constant pleas for help, your challenge is to maneuver little Mario up the steel structure, while helping him to avoid the rapid-fire succession of hazards that come his way. As little Mario gallantly battles his way up the barriers, he is taunted and teased by Donkey Kong, who brazenly struts back and forth, beating his chest in joyful exuberance at the prospect of having the beautiful girl all to himself. It is your job to get little Mario to the top. For it is there, and only there, that he can send the mighty Donkey Kong to his mortal doom. Leaving Little Mario and the beautiful girl to live happily ever after. "SIGH. SIGH." So, if you want the most exciting, most fun-filled, most talked about family video game on the market, don't monkey around with anything but the original Donkey Kong.

Gameplay
Donkey Kong stars Mario, who attempts to reach the top of a construction site where Lady is held captive. He can walk along platforms, jump, and climb ladders as well. In the process, Donkey Kong may attempt to hinder Mario from a higher location by sending obstacles at him. Mario has the ability to jump over these obstacles or obliterate them using a Hammer; in both cases, he obtains a number of points that are added to a score. However, if Mario ends up falling off the side of a platform and lands on one below him (or none), and the difference in height is greater than Mario's by one and a half, he loses a life. Each time Mario reaches Lady, Donkey Kong will carry her away on a pair of ladders to the next level until the fourth stage, where he is defeated upon completion.

Levels
Each of the 22 playable levels consists of those four screens:
 * 25 m
 * 50 m (removed in most versions)
 * 75 m (removed in some versions)
 * 100 m (removed in Game & Watch version)

After completing the fourth screen, 100 m, the player has reached the next level, which starts at 25 m again, but with increased difficulty like more frequent barrels and faster fireballs.

Killscreen in Level 22
Although the game is intended to be playable indefinitely by not having a level cap, it is impossible to complete the first screen of level 22, due to a glitch within the process of calculating the time limit. Said time limit is calculated using the formula (10 &times; level number) + 40 and shown in hundreds as a bonus counter in the top right edge of the screen. Because the calculated value is stored as an 8-Bit integer, which can only save 256 different values ranging from 0 to 255, and the formula results in a value of 260 for level 22, an integer overflow occurs and the value is saved modulo 256, which means 260 is saved as 4. This leads to a starting value of 400 for the timer of level 22, so that Mario dies a few seconds after starting the level, being unable to finish it.

Development
Donkey Kong was created in late 1980 when Shigeru Miyamoto, under the supervision of the late Gunpei Yokoi, was assigned by Nintendo to convert , a poorly selling arcade game in North America, into a game that would have more appeal to more gamers. Shigeru Miyamoto later admitted that he did not focus on the story of the game, instead creating a basic plot with colorful characters and music that he himself penned. He said that Mario and Lady were not intended to have a relationship, and he did not know where the idea came from, but he thought that it did not matter much. The game was also originally designed to have Mario escape from a maze, and jumping was not yet implemented, making platforming too difficult. In a time where arcade games took around two to three months to build, Donkey Kong was built in four or five months and Shigeru Miyamoto was focused on developing it for a global market rather than just for Japan. The final version of the game was a major breakthrough for Nintendo and for the video game industry, becoming one of the best selling arcade machines of its time. Its platforming gameplay also distinguished it from most other arcade games at the time.

Donkey Kong was originally conceived as a  game, with Bluto being in the spot of Donkey Kong, Popeye being Mario, and Olive Oyl being Lady. The particular Popeye short that inspired Yokoi is A Dream Walking which is set in a construction site. The game ended up being changed due to Nintendo being unable to secure the license for Popeye at the time. Nintendo would later secure a license, making the a year later in 1982.

Miyamoto envisioned Mario to be a young man at around 24 or 26 years old, describing Donkey Kong as Mario's pet who escaped and kidnapped his girlfriend.

Universal Studios lawsuit
In 1982, around a year after the game's release, sued Nintendo, claiming that Donkey Kong infringed on Universal Studios's intellectual property rights to the film . , attorney and future president of Nintendo of America, decided to fight the case and hired seasoned attorney to represent Nintendo. When Kirby showed that not only was Nintendo not in violation of any copyrights, but also that Universal Studios themselves had sued RKO Pictures in 1975 to prove that the plot of King Kong was in fact in the public domain, Judge Robert W. Sweet ruled in Nintendo's favor, ordering Universal to pay Nintendo $1.8 million in legal fees. In an ironic twist, Judge Sweet also ruled that Tiger's King Kong video game, licensed by Universal, infringed on Donkey Kong. After the victory, Nintendo awarded John Kirby with a $30,000 sailboat, christened the Donkey Kong, and gave him "exclusive worldwide rights to use the name for sailboats."

Crazy Kong
Crazy Kong was an officially-licensed clone of Donkey Kong manufactured by Falcon. On June 30, 1982, Nintendo of America filed a complaint toward Elcon Industries Inc., an arcade hardware manufacturer based in Michigan that sold Crazy Kong boards. The complaint alleged that the licensing agreement with Falcon explicitly forbade the manufacturing or export of Crazy Kong outside Japan. The case was taken to the United States District Court for the Eastern District of Michigan, which quickly ruled in favor of Nintendo.

Ikegami Tsushinki
As Nintendo's newly established video game division lacked programming manpower, the arcade version of Donkey Kong was programmed by Ikegami Tsushinki, a contractor that had worked for Nintendo for several of its arcade releases. For Donkey Kong's development, the two companies signed a contract which gave Ikegami Tsushinki exclusive rights to the manufacturing of Donkey Kong arcade boards.

In 1983, Ikegami Tsushinki sued Nintendo on the ground that the company had violated the contract and produced around 80,000 arcade boards on its own. Ikegami Tsushinki also sought compensation for the use of reverse-engineered Donkey Kong code in Donkey Kong Jr. and claimed it owned the copyright on ''Donkey Kongs code (while the contract did not specify ownership of the code, a judgment relating to ' set a precedent establishing computer code can be copyrighted ). In response, Nintendo claimed it owned Donkey Kong's code as Ikegami Tsushinki was hired as a sub-contractor.

The case went to the Tokyo District Court until March 26, 1990, at which point the two companies settled out of court. The lawsuit has often been stated to be the reason behind the lack of rereleases of the arcade version of Donkey Kong until 2018 and the existence of Donkey Kong Original Edition; Donkey Kong 64 nevertheless features a full port of the arcade version, albeit with slight differences as it closely imitates the source code.

Sequels
Donkey Kong has four sequels:
 * Donkey Kong Jr.
 * Donkey Kong II (Game & Watch)
 * Donkey Kong 3
 * Donkey Kong (Game Boy)

Ports
In addition to the arcade version, Donkey Kong was ported into several other gaming systems and computers:
 * NES
 * 50 m and most cutscenes have been removed.
 * Donkey Kong is recolored.
 * A new song was added for the title screen.
 * Game & Watch
 * Only one level appears. This level only has three floors, and Mario has to reach the top four times.
 * GBA as Classic NES Series: Donkey Kong. This version, as the title implies, is not based on the arcade version, but rather the NES version, meaning 50 m is also omitted.
 * e-Reader for the GBA as part of Series Two. It is also the NES version.
 * Family Computer Disk System Similar to NES version.
 * 50 m and 75 m have been cut out.
 * The game has much simpler graphics.
 * In 25 m:
 * Only one Hammer appears instead of two.
 * Donkey Kong does not throw the barrels, but they are automatically spawned.
 * Fires and blue barrels do not appear.
 * In 100 m, four large Fires spawn automatically, though additional Fires do not spawn. Cutscenes are also absent.
 * Shortly after its release, Coleco recalled this port due to it not working on original Atari 2600 models.
 * 50 m has been cut out.
 * The graphics more closely resemble the original game than the system's predecessor.
 * In 25 m, blue barrels do not appear, and are instead replaced by barrels that go sideways.
 * Lady's hat does not appear in 75 m.
 * The same title song from the NES port appears on the title screen.
 * 50 m has been cut out.
 * There is no jack on 75 m.
 * 50 m and 75 m have been cut out.
 * The game does not work on the Intellivision II due to an intentional cartridge lockout, meant to affect Coleco and other third party cartridge producers. The Intellivision II checks that valid numeric values have been put in the addresses used by the Exec routine's "Mattel Electronics Presents" startup screen. Donkey Kong skips this routine in favor of a custom Coleco startup screen, thus failing to pass the subsequent later check of the data. Donkey Kong Jr. (and other 3rd party games) would later work around this by putting appropriate values in the copyright memory locations, even though they still did not use the Exec's startup screen.
 * The Intellivision staff were very angry about the release of this port, speculating that Coleco made the game intentionally look bad visually so the ColecoVision version would look superior. The more likely outcome is that Coleco simply did not have much experience programming for the Intellivision hardware.
 * (Two official ports exist, one released in 1983 in North America by, and another released in 1986 in Europe by .)
 * Virtual Console
 * The first port, released in 2006, is essentially a direct port of the NES version.
 * The second port, entitled Donkey Kong Original Edition (ドンキーコング オリジナルエディション), attempted to adhere to the arcade version, and was pre-installed for the European release of the Mario 25th Anniversary limited edition red Wii in 2010. This version restored some missing animations and the level 50 m, which was cut from the NES version, although Donkey Kong mistakenly stands still in this level, and while the port's graphics are an improvement to the NES port, it is still inferior to the true arcade version, which remains unavailable on Virtual Console. This port was made available on the Nintendo eShop in Japan when a Club Nintendo member purchased the download version of one of two games, one of which was New Super Mario Bros. 2, from July 28, 2012 to September 2, 2012. A similar promotion took place in the US between October 1, 2012 and January 6, 2013, exclusively to members of Club Nintendo who have, within the aforementioned time frame, linked their systems to their Club Nintendo accounts and have purchased the downloadable version of one of five select 3DS titles (one of which was Paper Mario: Sticker Star). There are currently no plans for a wide release of this version in the U.S., although it was released in Europe for the 3DS eShop on September 18, 2014.
 * The NES and Famicom version of Donkey Kong is one of the 30 games included in the NES Classic Edition and Nintendo Classic Mini: Family Computer, respectively.
 * Nintendo Switch
 * Announced at E3 2018 and released as part of 's Arcade Archives brand, a port of the original arcade game titled Arcade Archives: Donkey Kong was released through the eShop on June 14, 2018, marking the first official release of the full arcade version of Donkey Kong since its original release 37 years earlier. The player can choose between playing the original Japanese release, the later Japanese release, and the international release of the game.

As a minigame
It is featured as a minigame in the following titles:
 * In Game & Watch Gallery 2 and Game & Watch Gallery 4, Donkey Kong (Game & Watch version) was one of the minigames. It could be played in both modern and classic modes.
 * Animal Crossing (NES version included as minigame)
 * Donkey Kong 64 (arcade version included as a minigame)
 * Super Smash Bros. Brawl and Super Smash Bros. for Wii U (NES version included as a Masterpiece; it starts on the third level, 75 m, which is also an unlockable stage in Super Smash Bros. Brawl and a starter in Super Smash Bros. for Wii U)
 * amiibo tap: Nintendo's Greatest Bits (NES version included as a "highlight"; the player can play on 25 m, 75 m and 100 m in three separate "scenes", each of which are 180 seconds long)

Staff
The arcade version was produced by Gunpei Yokoi. Shigeru Miyamoto and Hiroshi Yamauchi directed the game while an uncredited Ikegami Tsushinki did programming duties, later leading to a lawsuit over which company owned the arcade code's rights. Intelligent Systems' own website claims credit for developing the NES port for Nintendo, though neither the cartridge nor title screen mentions the company and the Iwata Ask interview released for New Super Mario Bros. Wii states the game was developed by Nintendo Research & Development 2. Landon Dyer programmed the DOS Version.

Although Ikegami Tsushinki is uncredited, a 1996 article published in Bit Magazine and written by one of the programmer involved, Hirohisa Komanome, reveals the name of the programmers who worked on the game.
