Nintendo Entertainment System(NES)

NES2

ニンテンドーエンターテインメントシステム（Nintendo Entertainment System）またはNESとは、北米およびブラジル、欧州、アジア、オーストラリアにおいて任天堂から発売された家庭用ゲーム機である。

日本で発売されたファミリーコンピュータ（Family Computer、ファミコン）をベースに、筐体の変更や各国への対応を施している。

概要

NESおよびファミコンは当時もっとも成功したゲーム機であり、任天堂によれば全世界で約6000万台が販売された。アタリショックで衰退したビデオゲーム業界を再び活性化し、ゲームデザインから商慣習に至るまでのあらゆる面で、以降の家庭用ゲーム機ビジネスの手本となった。当時としては斬新な横スクロールアクションゲームである『スーパーマリオブラザーズ』はこのゲーム機の最初にして最大のキラーソフトとなった。また、サードパーティーに対して初めて訴訟が提起されたゲーム機でもある。

北米では1985年に、ヨーロッパでは1986年に発売された。本体の外側に“Nintendo”の文字が大きく表記されていたためか、現地では「ニンテンドー」の愛称で親しまれた。なお、後にファミコンの後継機として日本で発売された「スーパーファミコン」は、欧米でもNESの後継機として“Super Nintendo Entertainment System（SNES）”の名称で発売された。

歴史

Advanced Video System

1980年代初頭の業務用ゲームでの成功を受けて任天堂は、テレビゲーム15、テレビゲーム6とは異なる、カートリッジを交換して様々なゲームをできる独自のゲーム機の生産を計画した。上村雅之らによって設計され1983年7月15日に14,800円で日本で発売されたファミリーコンピュータ（ファミコン）は、1984年末までには日本で一番売れるゲーム機になった。この成功に勇気付けられて任天堂はすぐに北米市場への進出を考えた。

当初はアタリブランドから、“Nintendo Advanced Video System”の名でファミコンを発売すべくアタリと交渉に入った。しかし、交渉をしている最中にアタリ・ショックによりアタリは会社が傾き、交渉は不成立に終わった。また、その頃、コレコが自社パソコン向けに『ドンキーコング』移植版の発売を発表。コレコの発表をアタリは任天堂とコレコが接近している兆候と受け取り、交渉を打ち切ったとされる。なお、コレコは自社の家庭用ゲーム機（コレコビジョン）への『ドンキーコング』の移植については任天堂から正規ライセンスを取得していたが、パソコンへの移植については任天堂の許可を受けずに行なっていたため、このパソコン版『ドンキーコング』の発売は断念された（コレコビジョン移植版は発売）。続いてキーボードとデータレコーダ、無線式ジョイスティック、BASIC言語を加えたファミコンをNintendo Advanced Video Systemの名で発売することを計画したが、これも立ち消えとなった。

最終的には1985年6月に任天堂はConsumer Electronics Showでファミコンのアメリカ版を発表した。外装と名称を一新、当初はニューヨーク市に5万台のみを投入。1985年10月18日には一部地域に限って出荷したが、大成功を受けて翌年2月には全米に出荷を広げた。こうしてNESは日本でのファミコンと同様に人気を集め、ビデオゲーム産業を再活性化する立役者となった。

NESは、249ドルの豪華版Deluxe Setと199ドルの廉価版Action Setが発売された。本体及びケーブル類、コントローラー2個、光線銃はどちらのセットにも共通で入っている。Deluxe Set には他にファミリーコンピュータ ロボット（海外名R.O.B., "Robotic Operating Buddy"）と対応ソフト『ジャイロ』（海外名Gyromite）、光線銃用ソフト『ダックハント』が付属する。Action Set にはそれらは無く、代わりに『スーパーマリオブラザーズ』と『ダックハント』を1つにまとめたカートリッジが付く。

アメリカ版に続き他の国々でもNESが発売された。欧州および豪州では大きく2つの地域に分けて販売網が構築された。イギリス・イタリア・オーストラリア（“地域A”と呼ばれる）での販売はマテルが受け持ち、イタリア以外のヨーロッパ大陸諸国（“地域B”）での販売は他の様々な会社によって行なわれた。一方、カセットのほとんどは任天堂から直接販売された。韓国では現代電子産業（現・ハイニックス半導体）が輸入元となりNES（“地域A”）を輸入し、「컴보이（コンボイ/COMBOY）」という名称に変更して販売した。これは現代電子産業が独自に行った輸入販売であり、任天堂との提携によるものではない。

1980年代後半において任天堂は日米の家庭用ゲーム機市場で圧倒的なシェアを握り、支配的存在だった。しかし、任天堂は1990年まで欧州支店を設けていなかったため、競合していたセガはこれに乗じてマスターシステムを多くの国でNES以上に売り上げている。ただし世界累計での販売台数はNESに遠く及ばない。

1990年代に入ると、16ビット機のセガ・ジェネシスなど機能的に優位な後発機が登場し、任天堂自身もSuper Nintendo Entertainment System（SNES）を発売するなど、NESは徐々に市場の主役の座を譲っていった。任天堂はNESのサポートを続け、途切れない本体への需要に応じるため1990年代前半には初代NESのハードウェアの欠点を改善した新版 NES2（日本におけるAV仕様ファミコンに相当）を発売した。しかし1995年には、売り上げの減少と新作ゲームの欠如を受けて、ニンテンドー・オブ・アメリカ（NOA）はNESの生産を終了した。

生産終了後の数年でレンタルビデオ店やガレージセール、フリーマーケット周辺に確立したコレクター市場でゲーム愛好家はNESを再評価した。エミュレーションの発達と併せて1990年代後半はNESにとって第二の黄金時代ともいうべきものだった。2000年以降は中古市場も枯渇し始め、ROMファイルを見つけることももはや難しくなくなった。エミュレーションへの興味の高まりと並行してNESのハードウェア改造ブームも勃興した。マニアたちはNESを完全に別の筐体に移し変えたり、部品取りや単に面白半分で解剖したりした。コントローラは改造の格好の対象で、パソコンとパラレルポートやUSBを介して接続できるように改造された。乾電池と液晶画面を加えて携帯ゲーム機に改造する者もいた。

2014年01月27日には任天堂が1990年のアメリカのゲーム大会用に116本のみ作った「Nintendo World Championships」というソフトのカートリッジがeBayに出品され、ラベルが破れていてシリアル番号が見えない状態にも拘らず300件を超える入札の末9万9902ドルで落札された。

ファミコンとの違い

NESは本質的にはファミコンと同じハードウェアだが、いくつか重要な違いがある。

筐体

ファミコンは上から挿入するカセットスロットと、前面に周辺機器を接続する15ピンの拡張端子を持ち、紅白に彩られている。対してNESは、前面から挿入するカセットスロット（しばしばビデオデッキやトースターに喩えられる）と、落ち着いた灰色と赤でまとめられている。拡張端子は底面にある。

カセット

ファミコンのカセット端子が60ピンなのに対しNESは72ピンで、サイズもやや大きい。つまり互換性がない。また、ピンの用途も異なる。ファミコンに2本あったカセット内蔵音源用端子が削除され、残り差し引き14本は底面の拡張端子と同じ物のカセット配線に10本、10NESと呼ばれる海賊版対策チップ用に4本が使われている。
なお、北米で販売された初期のゲーム（StackUPなど）は、単にファミコンカセットをNESに挿せるように変換アダプタを接続したものである。日米で同じ基板を使って費用と在庫量を削減するための方策である。NES用カセットをファミコンで使用するため、或いは逆にファミコン用カセットをNESで使用するアダプターは、非純正の物が現在でも流通している。

なお、日本国内でもNESとほぼ同じカートリッジを採用したファミコンソフトが存在するが、一般発売されておらずホテルや旅館に設置されていた業務用ファミコン『ファミコンボックス』やディスクカード書換機『ディスクライター』の専用カートリッジに採用されている。

周辺機器

ファミコン用には発売されたが、NES用は出なかった周辺機器やソフトウェアがいくつかある。

• ディスクシステム - 日本と台湾と香港でのみ発売されたファミコン用のディスクドライブである。任天堂は海賊版を危惧してその他の国では発売しなかった。Super Mario Bros. 2として発売された『夢工場ドキドキパニック』や『悪魔城ドラキュラ』シリーズのように、ディスクシステム用ソフトの多くがNES用カートリッジソフトとして移植されている。一方、オリジナルの『スーパーマリオブラザーズ2』は、SNES用ソフトSuper Mario All-StarsにSuper Mario Bros.: The Lost Levelsとして収録されるまで日本国外向けには発売されなかった。
• ファミリーベーシック - ファミコン用のBASIC言語である。自分用のゲームをプログラムできる。多くのプログラマがこの言語でプログラミングに入門した。
• 通信アダプタ - 任天堂のサーバに接続するためのモデムである。ジョークや（主に任天堂に関する）ニュース、攻略法、日本国内の天気予報が提供されていた。いくつかのプログラムもダウンロードできた。

カセット内蔵音源

NESでは音源信号入力のピンは底面の拡張端子のみで、ファミコンと異なりカセット端子には無い。結果的にNESはカセット版ソフトでは拡張音源を使用できなくなり、NES版ではファミコン版に比べて内蔵音源のみとなったソフトがいくつかある。『悪魔城伝説』（英：Castlevania III: Dracula's Curse）がこの問題の顕著な例である。

コントローラ

ファミコンとは違い、マイク付きのIIコンは無く、同一形状のコントローラーを2つ使用。また、本体直付けではなく取り外し可能だった。日本版のNEWファミコンにもNESのコントローラーが挿せるので、初代ファミコンと変わらない操作性で遊べると言う利点がある。

海賊版対策回路

ファミコンは海賊版対策回路を持たず、そのため極東では（非ライセンス品と無断複製版の両方の意味で）海賊版ソフトが氾濫した。対して、初代NESには10NESチップという対策回路が搭載され、無許可版の製作を著しく困難にした（ただしNES2には搭載されていない）。後に、NESを分解して10NESチップの4番ピンを切断すればチップを無効化でき、海賊版や輸入版ソフトが使えるほか、合法的なゲームの互換性も向上することが明らかになった。欧州版には地域Aと地域Bのゲームを相互にプレイできなくする対策チップが載っていた。

映像出力

初代ファミコンはRF出力のみ、AVファミコンはビデオ出力のみだったのに対し、NESはRF出力とビデオ出力の並存だった（フランス版はRGB出力端子もあるが、内部でコンポジット→RGB変換しているだけなので、RGBの高画質は期待できない）。ちなみにNES2はRF出力のみ、ヨーロッパ版では現地の仕様にあわせPALまたはSECAM出力となっている。

コントローラ

NESの標準コントローラは、ファミコンのIコントローラと同様の A、B、スタート、セレクトの四つのボタンと十字キーが配された長方形型のものが採用された。ファミコンとは異なりIコン・IIコンの差は無く、同じ形状の物が2つ同梱。また、本体に直付けではなく、本体前面に2つある7ピンのコントローラーコネクタに接続して使用する。

後に発売されたNES2では日本のAV仕様ファミコンと同様、スーパーファミコンのコントローラのように「犬の骨」を思わせる形となった。

近年、このコントローラのデザインはNESのシンボルとして認識されるようになった。任天堂は限定版ゲームボーイアドバンスSPや販売促進用商品といった最近の欧米向けの商品に、NESコントローラのデザインを模したものを発売している。

なお、NES ザッパー（光線銃相当品）、パワーパッド、R.O.B.、パワーグローブといった周辺機器の接続にも、コントローラ用コネクタがそのまま用いられた。

設計上の欠点

純正クリーニングキット

任天堂は、NES の北米市場進出の際にアタリショック以降のゲーム機全般に対する不評を回避すべくデザインの面から競合他機種との差別化を図った。そのひとつが、家電であるビデオデッキをイメージした本体前面に水平に挿入する ZIF 方式のカセットスロットである。だが、このカセットスロットは新品状態では特に問題はないが、カセット挿入時の力加減ではピンが折れ曲がったり、抜き差しの繰り返しによって比較的早くピンが摩耗した。これはコネクターに腐食しやすい安価な合金を使用したことが原因のひとつとされ、ゲームジニーなどの非ライセンス品の使用がこの問題を更に悪化させる要因となった。また、NES のコネクタはファミコンで採用されたエッジ・コネクタに比べてもちりやほこりに弱く、これも接触不良の原因となった。さらに、NES に搭載された 10NES と呼ばれる海賊版対策回路がこの問題に拍車をかけた。起動時にゲームソフトが正規品かどうかを確認する 10NES の動作タイミングは非常に厳格で、接触不良によるタイミングのズレから起動されずパワーランプが明滅を繰り返すという誤作動をしばしば引き起こした。これに対してユーザーは、コネクタに息を吹きかける、ゲーム機を叩く等の行為におよび、これらの行為がカセットやゲーム機本体の摩耗や破損につながった。

任天堂は、接触不良への対策として1989年に NES 用のクリーニングキットを発売。1993年に発売された NES2 では海賊版対策チップを搭載せず、カセットスロットも垂直挿入方式のエッジ・コネクタとした。また、ゲーム機の不具合に対応するためアメリカ中に任天堂の認可を受けた修理センターが作られた。

The Nintendo Entertainment System (also abbreviated as NES) is an 8-bit home video game console that was developed and manufactured by Nintendo. It was initially released in Japan as the Family Computer (Japanese: ファミリーコンピュータ, Hepburn: Famirī Konpyūta) (also known by the portmanteau abbreviation Famicom (ファミコン, Famikon) and abbreviated as FC) on July 15, 1983, and was later released in North America during 1985, in Europe during 1986, and Australia in 1987. In South Korea, it was known as the Hyundai Comboy (현대 컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. It was succeeded by the Super Nintendo Entertainment System.

The best-selling gaming console of its time, the NES helped revitalize the US video game industry following the video game crash of 1983. With the NES, Nintendo introduced a now-standard business model of licensing third-party developers, authorizing them to produce and distribute titles for Nintendo's platform.

In 2009, the Nintendo Entertainment System was named the single greatest video game console in history by IGN, in a list of 25. It is the second greatest console behind only the Sega Dreamcast in PC Magazine‍ '​s "Top 10 Video Game Consoles of All Time".

History

Development

Main article: History of the Nintendo Entertainment System

Following a series of arcade game successes in the early 1980s, Nintendo made plans to create a cartridge-based console called the Famicom. Masayuki Uemura designed the system. Original plans called for an advanced 16-bit system which would function as a full-fledged computer with a keyboard and floppy disk drive, but Nintendo president Hiroshi Yamauchi rejected this and instead decided to go for a cheaper, more conventional cartridge-based game console as he felt that features such as keyboards and disks were intimidating to non-technophiles. A test model was constructed in October 1982 to verify the functionality of the hardware, after which work began on programming tools. Because 65xx CPUs had not been manufactured or sold in Japan up to that time, no cross-development software was available and it had to be produced from scratch. Early Famicom games were written on a system that ran on an NEC PC-8001 computer and LEDs on a grid were used with a digitizer to design graphics as no software design tools for this purpose existed at that time.

The code name for the project was "GameCom", but Masayuki Uemura's wife proposed the name "Famicom", arguing that "In Japan, 'pasokon' is used to mean a personal computer, but it is neither a home or personal computer. Perhaps we could say it is a family computer." Meanwhile, Hiroshi Yamauchi decided that the console should use a red and white theme after seeing a billboard for DX Antenna which used those colors.

Original plans called for the Famicom's cartridges to be the size of a cassette tape, but ultimately they ended up being twice as big. Careful design attention was paid to the cartridge connectors since loose and faulty connections often plagued arcade machines. As it necessitated taking 60 connection lines for the memory and expansion, Nintendo decided to produce their own connectors in-house rather than use ones from an outside supplier.

The game pad controllers were more-or-less copied directly from the Game & Watch machines, although the Famicom design team originally wanted to use arcade-style joysticks, even taking apart ones from American game consoles to see how they worked. However, it was eventually decided that children might step on joysticks left on the floor and their durability was also questioned. Katsuyah Nakawaka attached a Game & Watch D-pad to the Famicom prototype and found that it was easy to use and had no discomfort. Ultimately though, they did install a 15-pin expansion port on the front of the console so that an arcade-style joystick could be used optionally. The controllers were hard-wired to the console with no connectors for cost reasons.

Uemura added an eject lever to the cartridge slot which was not really necessary, but he felt that children could be entertained by pressing it. He also added a microphone to the second controller with the idea that it could be used to make players' voices sound through the TV speaker.

Release

The console was released on July 15, 1983 as the Family Computer (or Famicom for short) for ¥14,800 alongside three ports of Nintendo's successful arcade games Donkey Kong, Donkey Kong Jr. and Popeye. The Famicom was slow to gather momentum; a bad chip set caused the initial release of the system to crash. Following a product recall and a reissue with a new motherboard, the Famicom’s popularity soared, becoming the best-selling game console in Japan by the end of 1984.

Encouraged by these successes, Nintendo soon turned its attention to the North American market. Nintendo entered into negotiations with Atari to release the Famicom under Atari’s name as the name Nintendo Advanced Video Gaming System. The deal was set to be finalized and signed at the Summer Consumer Electronics Show in June 1983. However, Atari discovered at that show that its competitor Coleco was illegally demonstrating its Coleco Adam computer with Nintendo's Donkey Kong game. This violation of Atari's exclusive license with Nintendo to publish the game for its own computer systems delayed the implementation of Nintendo's game console marketing contract with Atari. Atari's CEO Ray Kassar was fired the next month, so the deal went nowhere, and Nintendo decided to market its system on its own.

The proposed Advanced Video System bundle, including cassette drive and wireless accessories.

Subsequent plans to market a Famicom console in North America featuring a keyboard, cassette data recorder, wireless joystick controller and a special BASIC cartridge under the name "Nintendo Advanced Video System" likewise never materialized. By the beginning of 1985, the Famicom had sold more than 2.5 million units in Japan and Nintendo soon announced plans to release it in North America as the Advanced Video Entertainment System (AVS) that same year. The American video game press was skeptical that the console could have any success in the region, with the March 1985 issue of Electronic Games magazine stating that "the videogame market in America has virtually disappeared" and that "this could be a miscalculation on Nintendo's part."

At June 1985's Consumer Electronics Show (CES), Nintendo unveiled the American version of its Famicom. This is the system which would eventually be officially deployed as the Nintendo Entertainment System, or the colloquial "NES". Nintendo seeded these first systems to limited American test markets starting in New York City on October 18, 1985, following up with a full-fledged North American release of the console in February of the following year. Nintendo released 17 launch titles: 10-Yard Fight, Baseball, Clu Clu Land, Duck Hunt, Excitebike, Golf, Gyromite, Hogan’s Alley, Ice Climber, Kung Fu, Pinball, Soccer, Stack-Up, Tennis, Wild Gunman, Wrecking Crew, and Super Mario Bros. Some varieties of these launch games contained Famicom chips with an adapter inside the cartridge so they would play on North American consoles, which is why the title screen of "Gyromite" has the Famicom title "Robot Gyro" and the title screen of "Stack-Up" has the Famicom title "Robot Block".

R.O.B. (Robotic Operating Buddy), an accessory for the NES's 1985 launch. Although it ended up having a short product lifespan, R.O.B. was initially used to market the NES as novel and sophisticated compared to previous game consoles.

The system was originally targeted for release in the spring of 1985, but the release date was pushed back. After test-marketing in the New York City area in late fall, retailers had reportedly stated the system "failed miserably". Nintendo tried a second time; the system was test-marketed further beginning in February 1986, with the nationwide release occurring in September 1986.

For more details on this topic, see History of the Nintendo Entertainment System § North America.

The system's launch represented not only a new product, but also a reframing of the severely damaged home video game market segment as a whole. The video game market crash of 1983 had occurred in significant part due to a lack of consumer and retailer confidence in video games, which had in turn been due partially to confusion and misrepresentation in the marketing of video games. Prior to the NES, the packaging of many video games presented bombastic artwork which exaggerated the graphics of the actual game. In terms of product identity, a single game such as Pac-Man would appear in many versions on many different game consoles and computers, with large variations in graphics, sound, and general quality between the versions. By stark contrast, Nintendo's marketing strategy aimed to regain consumer and retailer confidence, by delivering a singular platform whose technology was not in need of heavy exaggeration and whose qualities were clearly defined.

To differentiate Nintendo's new home platform from the early 1980s' common perception of a beleaguered and frivolous video game market, the company freshened its product nomenclature and positioning, and it established a rigorous product approval and licensing policy. The overall system was referred to as an "Entertainment System" instead of a "video game system", which was centered upon a machine called a "Control Deck" instead of a "console", and which featured software cartridges called "Game Paks" instead of "video games". The 10NES lockout chip system acted as a lock-and-key coupling of each Game Pak and Control Deck, deterring the copying or production of NES games which had not first achieved Nintendo's licensed approval. The packaging of the launch lineup of NES games bore pictures of a very close representation of the actual onscreen graphics of the game, which were of sufficiently recognizable quality on their own. Symbols on the launch games' packaging clearly indicated the genre of the game, in order to reduce consumer confusion. A 'seal of quality' was printed on all appropriately licensed game and accessory packaging. The initial seal stated, "This seal is your assurance that Nintendo has approved and guaranteed the quality of this product". This text was later changed to "Official Nintendo Seal of Quality".

For more details on this topic, see Nintendo Entertainment System § Third-party licensing.

Unlike with the Famicom, Nintendo of America marketed the console primarily to children, instituting a rather strict policy of censoring profanity, sexual, religious, or political content in games. The most famous case of this was Lucasfilm's attempts to port Maniac Mansion (a game with a considerable amount of material Nintendo had issues with) to the NES. NOA continued their censorship policy until 1994 with the advent of the Entertainment Software Rating Board system.

The optional Robotic Operating Buddy, or R.O.B., was part of a marketing plan to portray the NES's technology as being novel and sophisticated when compared to previous game consoles, and to portray its position as being within reach of the better established toy market. While at first, the American public exhibited limited excitement for the console itself, peripherals such as the light gun and R.O.B. also attracted extensive attention.

In Europe and Australia, the system was released to two separate marketing regions. One region consisted of most of mainland Europe (excluding Italy), and distribution there was handled by a number of different companies, with Nintendo responsible for most cartridge releases. Most of this region saw a 1986 release. Mattel handled distribution for the other region, consisting of the United Kingdom, Ireland, Canada, Italy, Australia and New Zealand, starting the following year. Not until the 1990s did Nintendo's newly created European branch direct distribution throughout Europe.

The Nintendo Entertainment System's Control Deck

For its complete North American release, the Nintendo Entertainment System was progressively released over the ensuing years in four different bundles: the Deluxe Set, the Control Deck, the Action Set and the Power Set. The Deluxe Set, retailing at US$199.99 (equivalent to $474 in 2015), included R.O.B., a light gun called the NES Zapper, two controllers, and two Game Paks: Gyromite, and Duck Hunt. The Basic Set, retailing at US$89.99 with no game, and US$99.99 bundled with "Super Mario Bros." The Action Set, retailing in 1988 for US$149.99, came with the Control Deck, two game controllers, an NES Zapper, and a dual Game Pak containing both Super Mario Bros. and Duck Hunt. In 1989, the Power Set included the console, two game controllers, a NES Zapper, a Power Pad, and a triple Game Pak containing Super Mario Bros, Duck Hunt, and World Class Track Meet. In 1990, a Sports Set bundle was released, including the console, an NES Satellite infrared wireless multitap adapter, four game controllers, and a dual Game Pak containing Super Spike V'Ball and Nintendo World Cup. Two more bundle packages were later released using the original model NES console. The Challenge Set of 1992 included the console, two controllers, and a Super Mario Bros. 3 Game Pak for a retail price of US$89.99. The Basic Set, first released in 1987, was repackaged for a retail US$89.99. It included only the console and two controllers, and no longer was bundled with a cartridge. Instead, it contained a book called the Official Nintendo Player's Guide, which contained detailed information for every NES game made up to that point.

Finally, the console was redesigned for both the North American and Japanese markets as part of the final Nintendo-released bundle package. The package included the new style NES-101 console, and one redesigned "dogbone" game controller. Released in October 1993 in North America, this final bundle retailed for US$49.99 and remained in production until the discontinuation of the NES in 1995.

Reception

By 1988 industry observers stated that the NES's popularity had grown so quickly that the market for Nintendo cartridges was larger than that for all home computer software. Compute! reported in 1989 that Nintendo had sold seven million NES systems in 1988, almost as many as the number of Commodore 64s sold in its first five years. "Computer game makers [are] scared stiff", the magazine said, stating that Nintendo's popularity caused most to have poor sales during the previous Christmas and resulting in serious financial problems for some. By 1990 30% of American households owned the NES, compared to 23% for all personal computers.

Despite the system’s lackluster performance outside Japan and North America, by 1990 the NES had outsold all previously released consoles worldwide. The slogan for this brand was It can't be beaten. In Europe and South America, however, the NES was outsold by Sega's Master System, while the Nintendo Entertainment System was not available in the Soviet Union.

As the 1990s dawned, gamers predicted that competition from technologically superior systems such as the 16-bit Sega Mega Drive/Genesis would mean the immediate end of the NES’s dominance. Instead, during the first year of Nintendo's successor console the Super Famicom (named the Super Nintendo outside Japan), the Famicom remained the second highest-selling video game console in Japan, outselling the newer and more powerful NEC PC Engine and Sega Mega Drive by a wide margin. The console remained popular in Japan and North America until late 1993, when the demand for new NES software abruptly plummeted. The last game released in Japan was Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods was the last licensed game. In the wake of ever decreasing sales and the lack of new software titles, Nintendo of America officially discontinued the NES by 1995. Despite this, Nintendo of Japan kept producing new Nintendo Famicom units until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the decision to discontinue support to insufficient supplies of parts.

Legacy

The NES was released after the "video game crash" of the early 1980s, whereupon many retailers and adults had regarded electronic games as being merely a passing fad, and many believed at first that the NES was another fad. Before the NES/Famicom, Nintendo was known as a moderately successful Japanese toy and playing card manufacturer, and the popularity of the NES/Famicom helped the company grow into an internationally recognized name almost synonymous with video games as Atari had been during the 2600 era and set the stage for Japanese dominance of the video game industry. With the NES, Nintendo also changed the relationship of console manufacturers and third-party software developers by restricting developers from publishing and distributing software without licensed approval. This led to higher quality software titles, which helped to change the attitude of a public that had grown weary from poorly produced titles for other game systems of the day.

The NES hardware was also very influential. Nintendo chose the name "Nintendo Entertainment System" for the US market and redesigned the system so it would not give the appearance of a child's toy. The front-loading cartridge input allowed it to be used more easily in a TV stand with other entertainment devices, such as a video cassette player.

There were many prominent game franchises that originated on the NES. The system's hardware limitations led to game design similarities that still influence video game design and culture. Some of the more important franchises that debuted on the NES were Nintendo's own Super Mario Bros., The Legend of Zelda and Metroid, Capcom's Mega Man franchise, Konami's Castlevania franchise, Square's Final Fantasy and Enix's Dragon Quest franchises. All of these still exist today.

NES imagery, especially its controller, has become a popular motif for a variety of products, including Nintendo's own Game Boy Advance. Clothing, accessories, and food items adorned with NES-themed imagery are still produced and sold in stores. Such items include hats, shirts, underwear, wallets, wrist-bands, belt buckles, tins containing mint candy, and energy drinks.

Discontinuation

1995

On August 14, 1995, Nintendo discontinued the Nintendo Entertainment System in North America and in Europe.

Japan

The Famicom was originally discontinued on September 2003. However, Nintendo would repair parts of the console after its discontinuation in 2003. It was not until until 2007 that Nintendo announced they would stop repairing parts.

The Nintendo Entertainment System offered a number of groundbreaking titles. Super Mario Bros. pioneered side-scrollers while The Legend of Zelda helped popularize battery-backed save functionality.

Game Pak

Main article: Nintendo Entertainment System Game Pak

North American and PAL NES cartridges (or "Game Paks") are significantly larger than Japanese Famicom cartridges.

The NES uses a 72-pin design, as compared with 60 pins on the Famicom. To reduce costs and inventory, some early games released in North America were simply Famicom cartridges attached to an adapter to fit inside the NES hardware. Originally, NES cartridges were held together with five small slotted screws. Games released after 1987 were redesigned slightly to incorporate two plastic clips molded into the plastic itself, removing the need for the top two screws.

The back of the cartridge bears a label with instructions on handling. Production and software revision codes were imprinted as stamps on the back label to correspond with the software version and producer. With the exception of The Legend of Zelda and Zelda II: The Adventure of Link, manufactured in gold-plastic carts, all licensed NTSC and PAL cartridges are a standard shade of gray plastic. Unlicensed carts were produced in black, robin egg blue, and gold, and are all slightly different shapes than standard NES cartridges. Nintendo also produced yellow-plastic carts for internal use at Nintendo Service Centers, although these "test carts" were never made available for purchase. All licensed US cartridges were made by Nintendo, Konami and Acclaim. For promotion of DuckTales: Remastered, Capcom sent 150 limited-edition gold NES cartridges with the original game, featuring the Remastered art as the sticker, to different gaming news agencies. The instruction label on the back included the opening lyric from the show's theme song, "Life is like a hurricane".

Japanese (Famicom) cartridges are shaped slightly differently. While the NES used a 72-pin interface, the Famicom system used a 60-pin design. Unlike NES games, official Famicom cartridges were produced in many colors of plastic. Adapters, similar in design to the popular accessory Game Genie, are available that allow Famicom games to be played on an NES. In Japan, several companies manufactured the cartridges for the Famicom. This allowed these companies to develop their own customized chips designed for specific purposes, such as chips that increased the quality of sound in their games.

Third-party licensing

The Famicom Family mark appeared in games and peripherals released from 1988 and onward that were considered by Nintendo to be compatible with most Famicom consoles and official derivatives.

Nintendo's near monopoly on the home video game market left it with a degree of influence over the industry. Unlike Atari, which never actively courted third-party developers (and even went to court in an attempt to force Activision to cease production of Atari 2600 games), Nintendo had anticipated and encouraged the involvement of third-party software developers; strictly, however, on Nintendo's terms. Some of the Nintendo platform-control measures were adopted by later console manufacturers such as Sega, Sony, and Microsoft, although not as stringent.

To this end, a 10NES authentication chip was placed in every console and another was placed in every officially licensed cartridge. If the console's chip could not detect a counterpart chip inside the cartridge, the game would not load. Nintendo portrayed these measures as intended to protect the public against poor-quality games, and placed a golden seal of approval on all licensed games released for the system.

Nintendo was not as restrictive as Sega, which did not permit third-party publishing until Mediagenic in late summer 1988. Nintendo's intention, however, was to reserve a large part of NES game revenue for itself. Nintendo required that they be the sole manufacturer of all cartridges, and that the publisher had to pay in full before the cartridges for that game be produced. Cartridges could not be returned to Nintendo, so publishers assumed all the risk. As a result, some publishers lost more money due to distress sales of remaining inventory at the end of the NES era than they ever earned in profits from sales of the games. Because Nintendo controlled the production of all cartridges, it was able to enforce strict rules on its third-party developers, which were required to sign a contract by Nintendo that would obligate these parties to develop exclusively for the system, order at least 10,000 cartridges, and only make five games per year. A 1988 shortage of DRAM and ROM chips also reportedly caused Nintendo to only permit 25% of publishers' requests for cartridges. This was an average figure, with some publishers receiving much higher amounts and others almost none. GameSpy noted that Nintendo's "iron-clad terms" made the company many enemies during the 1980s. Some developers tried to circumvent the five game limit by creating additional company brands like Konami's Ultra Games label; others tried circumventing the 10NES chip.

Further information: § Unlicensed games

Nintendo was accused of antitrust behavior because of the strict licensing requirements. The United States Department of Justice and several states began probing Nintendo's business practices, leading to the involvement of Congress and the Federal Trade Commission (FTC). The FTC conducted an extensive investigation which included interviewing hundreds of retailers. During the FTC probe, Nintendo changed the terms of its publisher licensing agreements to eliminate the two-year rule and other restrictive terms. Nintendo and the FTC settled the case in April 1991, with Nintendo required to send vouchers giving a $5 discount off to a new game, to every person that had purchased a NES title between June 1988 and December 1990. GameSpy remarked that Nintendo's punishment was particularly weak giving the case's findings, although it has been speculated that the FTC did not want to damage the video game industry in the United States.

In the longer run, however, with the NES near its end of its life many third-party publishers such as Electronic Arts supported upstart competing consoles with less onerous licensing terms such as the Sega Genesis and then the PlayStation, which eroded and then took over Nintendo's dominance in the home console market, respectively. Consoles from Nintendo's rivals in the post-SNES era had always enjoyed much stronger third-party support than Nintendo, which relied more heavily on first-party games.

Unlicensed games

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.

Atari Games created a line of NES products under the name Tengen and took a different approach. The company attempted to reverse engineer the lockout chip to develop its own "Rabbit" chip. However, Tengen also obtained a description of the lockout chip from the United States Patent and Trademark Office by falsely claiming that it was required to defend against present infringement claims in a legal case. Nintendo sued Tengen for copyright infringement, which Tengen lost as it could not prove that the legally obtained patent documents had not been used by the reverse engineering team. Tengen's antitrust claims against Nintendo were never finally decided.

Color Dreams produced Christian video games under the subsidiary name Wisdom Tree. They were never sued by Nintendo as the company probably feared a public relations backlash.

Emulation

Further information: List of video game emulators § Nintendo Entertainment System

The NES can be emulated on many other systems, most notably the PC. The first emulator was the Japanese-only Pasofami. It was soon followed by iNES, which was available in English and was cross-platform, in 1996. It was described as being the first NES emulation software that could be used by a non-expert. NESticle, a popular MS-DOS emulator, was released on April 3, 1997. There have since been many other emulators. The Virtual Console for the Wii, Nintendo 3DS and Wii U also offers emulation of many NES games.

Game rentals

As the Nintendo Entertainment System grew in popularity and entered millions of American homes, some small video rental shops began buying their own copies of NES games, and renting them out to customers for around the same price as a video cassette rental for a few days. Nintendo received no profit from the practice beyond the initial cost of their game, and unlike movie rentals, a newly released game could hit store shelves and be available for rent on the same day. Nintendo took steps to stop game rentals, but didn't take any formal legal action until Blockbuster Video began to make game rentals a large-scale service. Nintendo claimed that allowing customers to rent games would significantly hurt sales and drive up the cost of games. Nintendo lost the lawsuit, but did win on a claim of copyright infringement. Blockbuster was banned from including original, copyrighted instruction booklets with their rented games. In compliance with the ruling, Blockbuster produced their own short instructions—usually in the form of a small booklet, card, or label stuck on the back of the rental box—that explained the game's basic premise and controls. Video rental shops continued the practice of renting video games and still do today.

There were some risks with renting cartridge-based games, however. Most rental shops did not clean the connectors and they would become dirty over time. Renting and using a cartridge with dirty connectors posed a problem for consoles, especially the Nintendo Entertainment System which was particularly susceptible to operation problems and failures when its internal connectors became dirty (see the Design flaws section below).

Hardware

Configurations

Although the Japanese Famicom, North American and European NES versions included essentially the same hardware, there were certain key differences among the systems.

The original Japanese Famicom was predominantly white plastic, with dark red trim. It featured a top-loading cartridge slot, grooves on both sides of the deck in which the hardwired game controllers could be placed when not in use, and a 15-pin expansion port located on the unit's front panel for accessories.

The original NES, meanwhile, featured a front-loading cartridge covered by a small, hinged door that can be opened to insert or remove a cartridge and closed at other times. It features a more subdued gray, black, and red color scheme. An expansion port was found on the bottom of the unit and the cartridge connector pinout was changed.

In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.

The NES-101 control deck alongside its similarly redesigned NES-039 game controller.

In October 1993, Nintendo redesigned the NES to follow many of the same design cues as the newly introduced Super Nintendo Entertainment System and the Japanese Super Famicom. Like the SNES, the NES-101 model loaded cartridges through a covered slot on top of the unit replacing the complicated mechanism of the earlier design. For this reason the NES-101 is known informally as the "top-loader" among Nintendo fans.

The HVC-101 control deck alongside its similarly redesigned HVC-102 game controller.

In December 1993, the Famicom received a similar redesign. It also loads cartridges through a covered slot on the top of the unit and uses non-hardwired controllers. Because HVC-101 used composite video output instead of being RF only like the HVC-001, Nintendo marketed the newer model as the AV Famicom (AV仕様ファミコン, Eibui Shiyō Famikon). Since the new controllers don't have microphones on them like the second controller on the original console, certain games such as the Disk System version of The Legend of Zelda and Raid on Bungeling Bay will have certain tricks that cannot be replicated when played on an HVC-101 Famicom without a modded controller. However, the HVC-101 Famicom is compatible with most NES controllers due to having the same controller port. Nintendo had also released a 3D graphic capable headset. However, this peripheral was never released outside of Japan.

Design flaws

The official NES Cleaning Kit was intended to address flaws in the NES design that caused cartridge connectors to be particularly susceptible to interference from dirt and dust.

When Nintendo released the NES in the US, the design styling was deliberately different from that of other game consoles. Nintendo wanted to distinguish its product from those of competitors and to avoid the generally poor reputation that game consoles had acquired following the video game crash of 1983. One result of this philosophy was to disguise the cartridge slot design as a front-loading zero insertion force (ZIF) cartridge socket, designed to resemble the front-loading mechanism of a VCR. The newly designed connector worked quite well when both the connector and the cartridges were clean and the pins on the connector were new. Unfortunately, the ZIF connector was not truly zero insertion force. When a user inserted the cartridge into the NES, the force of pressing the cartridge down and into place bent the contact pins slightly, as well as pressing the cartridge’s ROM board back into the cartridge itself. Frequent insertion and removal of cartridges caused the pins to wear out from repeated usage over the years and the ZIF design proved more prone to interference by dirt and dust than an industry-standard card edge connector. These design issues were not alleviated by Nintendo’s choice of materials; the console slot nickel connector springs would wear due to design and the game cartridge copper connectors were also prone to tarnishing. Many players would try to alleviate issues in the game caused by this corrosion by blowing into the cartridges, then reinserting them, which actually hurt the copper connectors by speeding up the tarnishing.

The 10NES authentication chip contributed to the system's reliability problems. The circuit was ultimately removed from the remodeled NES 2.

Lockout

The Famicom contained no lockout hardware and, as a result, unlicensed cartridges (both legitimate and bootleg) were extremely common throughout Japan and the Far East. The original NES (but not the top-loading NES-101) contained the 10NES lockout chip, which significantly increased the challenges faced by unlicensed developers. Tinkerers at home in later years discovered that disassembling the NES and cutting the fourth pin of the lockout chip would change the chip’s mode of operation from "lock" to "key", removing all effects and greatly improving the console’s ability to play legal games, as well as bootlegs and converted imports. NES consoles sold in different regions had different lockout chips, so games marketed in one region would not work on consoles from another region. Known regions are: USA/Canada (3193 lockout chip), most of Europe (3195), Asia (3196) and UK, Italy and Australia (3197). Since two types of lockout chip were used in Europe, European NES game boxes often had an "A" or "B" letter on the front, indicating whether the game is compatible with UK/Italian/Australian consoles (A), or the rest of Europe (B). Rest-of-Europe games typically had text on the box stating "This game is not compatible with the Mattel or NES versions of the Nintendo Entertainment System". Similarly, UK/Italy/Australia games stated "This game is only compatible with the Mattel or NES versions of the Nintendo Entertainment System".

Pirate cartridges for the NES were rare, but Famicom ones were common and widespread in Asia. Most were produced in Hong Kong or Taiwan, and they usually featured a variety of small (32k or less) games which were selected from a menu and bank switched. Some were also hacks of existing games (especially Super Mario Bros.), and a few were cartridge conversions of Famicom Disk System titles such as the Japanese SMB2.

Problems with the 10NES lockout chip frequently resulted in the console's most infamous problem: the blinking red power light, in which the system appears to turn itself on and off repeatedly because the 10NES would reset the console once per second. The lockout chip required constant communication with the chip in the game to work. Dirty, aging and bent connectors would often disrupt the communication, resulting in the blink effect. Alternatively, the console would turn on but only show a solid white, gray, or green screen. Users attempted to solve this problem by blowing air onto the cartridge connectors, inserting the cartridge just far enough to get the ZIF to lower, licking the edge connector, slapping the side of the system after inserting a cartridge, shifting the cartridge from side to side after insertion, pushing the ZIF up and down repeatedly, holding the ZIF down lower than it should have been, cleaning the connectors with alcohol. These attempted solutions often became notable in their own right and are often remembered alongside the NES. Many of the most frequent attempts to fix this problem instead ran the risk of damaging the cartridge and/or system. In 1989, Nintendo released an official NES Cleaning Kit to help users clean malfunctioning cartridges and consoles.

With the release of the top-loading NES-101 (NES 2) toward the end of the NES's lifespan, Nintendo resolved the problems by switching to a standard card edge connector and eliminating the lockout chip. All of the Famicom systems used standard card edge connectors, as did Nintendo’s subsequent game consoles, the Super Nintendo Entertainment System and the Nintendo 64.

In response to these hardware flaws, "Nintendo Authorized Repair Centers" sprang up across the U.S. According to Nintendo, the authorization program was designed to ensure that the machines were properly repaired. Nintendo would ship the necessary replacement parts only to shops that had enrolled in the authorization program. In practice, the authorization process consisted of nothing more than paying a fee to Nintendo for the privilege. In a recent trend, many sites have sprung up to offer Nintendo repair parts, guides, and services that replace those formerly offered by the authorized repair centers.

Famicom 3D System

Nintendo released a 3D headset peripheral called Famicom 3D System for 3D stereoscopic entertainment. However, this was never released outside of Japan, since it was an utter commercial failure, making gamers experience headaches and nausea.

Famicom Modem

Nintendo released a modem peripheral called Famicom Modem. However, this was not intended for children. Instead, adults would use it for gambling horse races, set stocking dates, use their bank, and more.

Technical specifications

Main article: Nintendo Entertainment System technical specifications

For its central processing unit (CPU), the NES uses an 8-bit microprocessor produced by Ricoh based on a MOS Technology 6502 core.

The NES contains 2 kB of onboard work RAM. A game cartridge may contain expanded RAM to increase this amount. The size of NES games varies from 8 kB (Galaxian) to 1 MB (Metal Slader Glory), but 128 to 384 kB was the most common.

The NES uses a custom-made Picture Processing Unit (PPU) developed by Ricoh. All variations of the PPU feature 2 kB of video RAM, 256 bytes of on-die "object attribute memory" (OAM) to store the positions, colors, and tile indices of up to 64 sprites on the screen, and 28 bytes of on-die palette RAM to allow selection of background and sprite colors. The console's 2 kB of onboard RAM may be used for tile maps and attributes on the NES board and 8 kB of tile pattern ROM or RAM may be included on a cartridge. The system has an available color palette of 48 colors and 6 grays. Up to 25 simultaneous colors may be used without writing new values mid-frame: a background color, four sets of three tile colors and four sets of three sprite colors. The NES palette is based on NTSC rather than RGB values. A total of 64 sprites may be displayed onscreen at a given time without reloading sprites mid-screen. The standard display resolution of the NES is 256 horizontal pixels by 240 vertical pixels.

Video output connections varied from one model of the console to the next. The original HVC-001 model of the Family Computer featured only radio frequency (RF) modulator output. When the console was released in North America and Europe, support for composite video through RCA connectors was added in addition to the RF modulator. The HVC-101 model of the Famicom dropped the RF modulator entirely and adopted composite video output via a proprietary 12-pin "multi-out" connector first introduced for the Super Famicom/Super Nintendo Entertainment System. Conversely, the North American re-released NES-101 model most closely resembled the original HVC-001 model Famicom, in that it featured RF modulator output only. Finally, the PlayChoice-10 utilized an inverted RGB video output.

The stock NES supports a total of five sound channels, two of which are pulse channels with 4 pulse width settings, one is a triangle wave generator, another is a noise generator (often used for percussion), and the 5th one plays low-quality digital samples.

The NES supports expansion chips contained in certain cartridges to add sound channels and help with data processing. Developers can add these chips to their games, such as the Konami VRC6, Konami VRC7, Sunsoft 5B, Namco 163, and two more by Nintendo itself: the Nintendo FDS wave generator (a modified Ricoh RP2C33 chip with single-cycle wavetable-lookup sound support), and the Nintendo Memory Management Controller 5 (MMC5).

Accessories

In addition to featuring a revised color scheme that matched the more subdued tones of the console itself, NES controllers could be unplugged. They nevertheless lacked the microphone featured in Famicom controllers.

Controllers

The game controller used for both the NES and the Famicom featured an oblong brick-like design with a simple four button layout: two round buttons labeled "A" and "B", a "START" button and a "SELECT" button. Additionally, the controllers utilized the cross-shaped joypad, designed by Nintendo employee Gunpei Yokoi for Nintendo Game & Watch systems, to replace the bulkier joysticks on earlier gaming consoles’ controllers.

The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.

The NES dropped the hardwired controllers, instead featuring two custom 7-pin ports on the front of the console. Also in contrast to the Famicom, the controllers included with the NES were identical to each other—the second controller lacked the microphone that was present on the Famicom model and possessed the same START and SELECT buttons as the primary controller. Some NES localizations of games, such as The Legend of Zelda, which required the use of the Famicom microphone in order to kill certain enemies, suffered from the lack of hardware to do so.

The NES Zapper, a light gun accessory

A number of special controllers designed for use with specific games were released for the system, though very few such devices proved particularly popular. Such devices included, but were not limited to, the Zapper (a light gun), the R.O.B., and the Power Pad. The original Famicom featured a deepened DA-15 expansion port on the front of the unit, which was used to connect most auxiliary devices. On the NES, these special controllers were generally connected to one of the two control ports on the front of the console.

Nintendo also made two turbo controllers for the NES called NES Advantage and the NES Max. Both controllers had a Turbo feature, a feature where one tap of the button represented multiple taps. This feature allowed players to shoot much faster during shooter games. The NES Advantage had two knobs that adjusted the firing rate of the turbo button from quick to Turbo, as well as a "Slow" button that slowed down the game by rapidly pausing the game. The "Slow" button did not work with games that had a pause menu or pause screen and can interfere with jumping and shooting. The NES Max also had the Turbo Feature, but it was not adjustable, in contrast with the Advantage. It also did not have the "Slow" button. Its wing-like shape made it easier to hold than the Advantage and it also improved on the joystick. Turbo features were also featured on the NES Satellite, the NES Four Score, and the U-Force. Other accessories include the Power Pad and the Power Glove, which was featured in the movie The Wizard.

Near the end of the NES's lifespan, upon the release of the AV Famicom and the top-loading NES 2, the design of the game controllers was modified slightly. Though the original button layout was retained, the redesigned device abandoned the brick shell in favor of a dog bone shape. In addition, the AV Famicom joined its international counterpart and dropped the hardwired controllers in favor of detachable controller ports. However, the controllers included with the Famicom AV had cables which were 90 cm (3 feet) long, as opposed to the standard 180 cm(6 feet) of NES controllers.

The Dogbone controller for the AV Famicom.

In recent years, the original NES controller has become one of the most recognizable symbols of the console. Nintendo has mimicked the look of the controller in several recent products, from promotional merchandise to limited edition versions of the Game Boy Advance.

Japanese accessories

The Japanese Famicom has BASIC support with the Family BASIC keyboard.

A number of peripheral devices and software packages were released for the Famicom. Few of these devices were ever released outside Japan.

Family BASIC is an implementation of BASIC for the Famicom, packaged with a keyboard. Similar in concept to the Atari 2600 BASIC cartridge, it allows the user to program their own games, which can be saved on an included cassette recorder. Nintendo of America rejected releasing Famicom BASIC in the US because they did not think it fit their primary marketing demographic of children.

The Famicom Modem connected a Famicom to a now defunct proprietary network in Japan which provided content such as financial services. A dialup modem was never released for NES.

Family Computer Disk System

The Famicom Disk System was a peripheral available only for the Japanese Famicom that used games stored on "Disk Cards" with a 3" Quick Disk mechanism.

Main article: Family Computer Disk System

See also: Memory management controller § Famicom Disk System

In 1986, Nintendo released the Famicom Disk System (FDS) in Japan, a type of floppy drive that uses a single-sided, proprietary 5 cm (2") disk and plugs into the cartridge port. It contains RAM for the game to load into and an extra single-cycle wavetable-lookup sound chip. The disks were originally obtained from kiosks in malls and other public places where buyers could select a title and have it written to the disk. This process would cost less than cartridges and users could take the disk back to a vending booth and have it rewritten with a new game. The disks were used both for storing the game and saving progress and total capacity was 128k (64k per side).

Further information: Family Computer Disk System § Disk Writer and Disk Fax kiosks

A variety of games for the FDS were released by Nintendo (including some like Super Mario Bros. which had already been released on cartridge) and third party companies such as Konami and Taito. A few unlicensed titles were made as well. However, its limitations became quickly apparent as larger ROM chips were introduced, allowing cartridges with greater than 128k of space. More advanced memory management chips (MMC) soon appeared and the FDS quickly became obsolete. Nintendo also charged developers considerable amounts of money to produce FDS games, and many refused to develop for it, instead continuing to make cartridge titles. Many FDS disks have no dust covers (except in some unlicensed and bootleg variants) and are easily prone to getting dirt on the media. In addition, the drive use a belt which breaks frequently and requires invasive replacement. After only two years, the FDS was discontinued, although vending booths remained in place until 1993 and Nintendo continued to service drives, and to rewrite and offer replacement disks until 2003.

Nintendo of America initially planned to bring the FDS to the United States, but rejected the idea after considering the numerous problems encountered with them in Japan. Many FDS games such as Castlevania, Zelda, and Bubble Bobble were sold in the US as cartridge titles, with simplified sound and the disk save function replaced by passwords or battery save systems.

Hardware clones

Pirated clones of NES hardware remained in production for many years after the original had been discontinued. Some clones play cartridges from multiple systems, such as this FC Twin that plays NES and SNES games.

Main article: Nintendo Entertainment System hardware clone

A thriving market of unlicensed NES hardware clones emerged during the climax of the console's popularity. Initially, such clones were popular in markets where Nintendo never issued a legitimate version of the console. In particular, the Dendy (Russian: Де́нди), an unlicensed hardware clone produced in Taiwan and sold in the former Soviet Union, emerged as the most popular video game console of its time in that setting and it enjoyed a degree of fame roughly equivalent to that experienced by the NES/Famicom in North America and Japan. A Famicom clone was marketed in Argentina under the name of "Family Game", resembling the original hardware design. The Micro Genius (Simplified Chinese: 小天才) was marketed in Southeast Asia as an alternative to the Famicom; Samurai was the popular PAL alternative to the NES; and in Central Europe, especially Poland, the Pegasus was available. Samurai was also available in India in early 90s which was the first instance of console gaming in India.

The unlicensed clone market has flourished following Nintendo's discontinuation of the NES. Some of the more exotic of these resulting systems have gone beyond the functionality of the original hardware and have included variations such as a portable system with a color LCD (e.g. PocketFami). Others have been produced with certain specialized markets in mind, such as an NES clone that functions as a rather primitive personal computer, which includes a keyboard and basic word processing software. These unauthorized clones have been helped by the invention of the so-called NES-on-a-chip.

As was the case with unlicensed software titles, Nintendo has typically gone to the courts to prohibit the manufacture and sale of unlicensed cloned hardware. Many of the clone vendors have included built-in copies of licensed Nintendo software, which constitutes copyright infringement in most countries.

Although most hardware clones were not produced under license by Nintendo, certain companies were granted licenses to produce NES-compatible devices. The Sharp Corporation produced at least two such clones: the Twin Famicom and the SHARP 19SC111 television. The Twin Famicom was compatible with both Famicom cartridges and Famicom Disk System disks. It was available in two colors (red and black) and used hardwired controllers (as did the original Famicom), but it featured a different case design. The SHARP 19SC111 television was a television which included a built-in Famicom. A similar licensing deal was reached with Hyundai Electronics, who licensed the system under the name Comboy in the South Korean market. This deal with Hyundai was made necessary because of the South Korean government's wide ban on all Japanese "cultural products", which remained in effect until 1998 and ensured that the only way Japanese products could legally enter the South Korean market was through licensing to a third-party (non-Japanese) distributor (see also Japan–Korea disputes).

NES Test Station

The NES Test station (Lower Left), SNES counter tester (Lower Right), SNES test cart (Upper Right), And the original TV that came with the unit (Upper Left).

The NES Test Station was a diagnostics machine for the Nintendo Entertainment System introduced in 1988.

It was a NES-based unit designed for testing NES hardware, components and games. It was only provided for use in World of Nintendo boutiques as part of the Nintendo World Class Service program. Visitors were to bring items to test with the station, and could be assisted by a store technician or employee.

The NES Test Station's front features a Game Pak slot and connectors for testing various components (AC adapter, RF switch, Audio/Video cable, NES Control Deck, accessories and games), with a centrally-located selector knob to chose which component to test. The unit itself weighs approximately 11.7 pounds without a TV. It connects to a television via a combined A/V and RF Switch cable. By actuating the green button, a user can toggle between an A/V Cable or RF Switch connection. The television it is connected to (typically 11" to 14") is meant to be placed atop it.

At the front of the Test Station are three colored switches, from left to right: a green switch for alternating between A/V and RF connections when testing an NES Control Deck, a blue Reset switch, and an illuminated red Power switch. The system can test:

• Game Paks (When set to this, the test station would run like a normal NES.)
• Control Deck and Accessories (NES controllers, the NES Zapper, R.O.B. and Power Pad)
• AV Cables
• AC Adapters
• RF Switches

Upon connecting an RF, AV, or AC adapter to the test station, the system displays a 'Pass' or 'Fail' result.

There was a manual included with the test station to help the user understand how to use the equipment, or how to make repairs. The manual came in a black binder with a Nintendo World Class Service logo on the front. Nintendo ordered the older manuals destroyed when an updated manual was issued, due to the manuals' confidential content.

In 1991, Nintendo provided an add-on called the "Super NES Counter Tester" that tests Super Nintendo components and games. The SNES Counter Tester is a standard SNES on a metal fixture with the connection from the back of the SNES re-routed to the front of the unit. These connections may be made directly to the test station or to the TV, depending on what is to be tested.

Notes

^ a: For distribution purposes, Europe and Australasia were divided into two regions by Nintendo. The first of these regions consisted of France, the Netherlands, West Germany, Norway, Denmark, and Sweden and saw the NES released during 1986. The console was released in the second region, consisting of the United Kingdom, the Republic of Ireland, and Italy, as well as Australia and New Zealand, in 1987.
^ b: In Japan, Nintendo sold an optional expansion peripheral for the Famicom, called the Famicom Disk System, which would enable the console to run software from proprietary floppy disks.
^ c: The original Famicom included no dedicated controller ports. See game controllers section.
^ e: The NES was the overall best-selling system worldwide of its time. In Japan and the United States, it controlled 85 to 90 percent of the market. It was not as successful in Europe, where it was at in most ten to twelve percent of households. Nintendo sold 61.9 million NES units worldwide: 19.35 million in Japan, 34 million in the Americas and 8.5 million in other regions.
^ f: The commonly bundled game Super Mario Bros. popularized the platform game genre and introduced elements that would be copied in many subsequent games
^ g: Atari broke off negotiations with Nintendo in response to Coleco's unveiling of an unlicensed port of Donkey Kong for its Coleco Adam computer system. Although the game had been produced without Nintendo's permission or support, Atari took its release as a sign that Nintendo was dealing with one of its major competitors in the market.
^ h: Donkey Kong Jr. Math and Mach Rider are often erroneously included in lists of launch titles. In reality, neither title was available until later in 1986.
