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 1987, and Australia in 1987. In South Korea, it was known as the Hyundai Comboy (현대컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. 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. It was succeeded by the Super Nintendo Entertainment System.
Document 6: List of Super Nintendo Entertainment System games: Of the console's 783 official releases, 249 were exclusive to North America and 62 to Europe. The Super NES was released in North America on August 23, 1991 with its launch titles being Super Mario World, F - Zero, Pilotwings, SimCity, and Gradius III. The last game to be officially published for the system was Frogger in 1998. The best - selling game is Super Mario World with over 20.6 million units sold.

Document 8: Nintendo Entertainment System: 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 $475 in 2016), 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.
Document 9: Nintendo Entertainment System: 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.
Document 10: Pokémon Mini: The (officially stylized as Pokémon mini) is a handheld game console that was designed and manufactured by Nintendo and themed around the "Pokémon" media franchise. It is the smallest game system with interchangeable cartridges ever produced by Nintendo, weighing just under . It was first released in North America on November 16, 2001, then in Japan on December 14, 2001, and in Europe on March 15, 2002. The systems were released in three colors: Wooper Blue, Chikorita Green, and Smoochum Purple.
Document 11: Nintendo Entertainment System: 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.
Document 12: Nintendo Entertainment System: 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.h[›] 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".
Document 13: Nintendo Switch: The Switch includes 32 GB of internal storage, and can be expanded up to 2 TB using a microSD, a microSDHC or a microSDXC card. If the microSD card is used, the Switch will only store game save data on the internal memory, leaving data that can be re-acquired on the microSD card. Save data will always be stored on the console, regardless if the source is a physical Game Card or a digital download copy. At launch, there was no way to transfer save files from the internal memory to the microSD card or another Switch console, though save game and profile transfers between Switch consoles were added in a system's 4.0. 0 update in October 2017. While microSD and microSDHC support was available at launch, microSDXC card support was later added to device's software via a system update. The Switch does not support external storage units at launch, but Nintendo stated that they were looking into adding this feature in the future.
Document 14: Nintendo Entertainment System: 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 Super Nintendo Entertainment System 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 final Famicom game released in Japan is Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods is the final 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. However, Nintendo kept producing new Famicom units in Japan until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the discontinuation of support to insufficient supplies of parts.
Document 15: Super Nintendo Entertainment System: Internally, a regional lockout chip (CIC) within the console and in each cartridge prevents PAL region games from being played on Japanese or North American consoles and vice versa. The Japanese and North American machines have the same region chip. This can be overcome through the use of adapters, typically by inserting the imported cartridge in one slot and a cartridge with the correct region chip in a second slot. Alternatively, disconnecting one pin of the console's lockout chip will prevent it from locking the console; hardware in later games can detect this situation, so it later became common to install a switch to reconnect the lockout chip as needed.
