Document 4: 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 5: 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 6: 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 7: 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 8: Nintendo Entertainment System: The Nintendo Entertainment System (commonly 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 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 9: Dance Dance Revolution: "Dance Dance Revolution" has been met with critical acclaim for its originality and stamina in the video game market. There have been dozens of arcade-based releases across several countries and hundreds of home video game console releases, promoting a music library of original songs produced by Konami's in-house artists and an eclectic set of licensed music from many different genres. The "DDR" series has inspired similar games such as "Pump it Up" by Andamiro and "In the Groove" by Roxor Games. The series' current version is "Dance Dance Revolution A20", released in 2019.
Document 10: IPod: iPods have won several awards ranging from engineering excellence,[not in citation given] to most innovative audio product, to fourth best computer product of 2006. iPods often receive favorable reviews; scoring on looks, clean design, and ease of use. PC World says that iPod line has "altered the landscape for portable audio players". Several industries are modifying their products to work better with both the iPod line and the AAC audio format. Examples include CD copy-protection schemes, and mobile phones, such as phones from Sony Ericsson and Nokia, which play AAC files rather than WMA.
Document 11: The Legend of Zelda: Twilight Princess: Twilight Princess received the awards for Best Artistic Design, Best Original Score, and Best Use of Sound from IGN for its GameCube version. Both IGN and Nintendo Power gave Twilight Princess the awards for Best Graphics and Best Story. Twilight Princess received Game of the Year awards from GameTrailers, 1UP.com, Electronic Gaming Monthly, Game Informer, Games Radar, GameSpy, Spacey Awards, X-Play and Nintendo Power. It was also given awards for Best Adventure Game from the Game Critics Awards, X-Play, IGN, GameTrailers, 1UP.com, and Nintendo Power. The game was considered the Best Console Game by the Game Critics Awards and GameSpy. The game placed 16th in Official Nintendo Magazine's list of the 100 Greatest Nintendo Games of All Time. IGN ranked the game as the 4th-best Wii game. Nintendo Power ranked the game as the third-best game to be released on a Nintendo system in the 2000s decade.
Document 12: 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. Despite the console's relatively late start, and the fierce competition it faced in North America and Europe from Sega's Genesis / Mega Drive console, it was the best - selling console of its era.
Document 13: 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 14: Warlocked: Warlocked is a real-time strategy video game developed by Bits Studios and published by Nintendo for the Game Boy Color. Critical reception towards the game was positive, it received a score of 86% on review aggregation website GameRankings. IGN named the game as the Best Game Boy Strategy game of 2000, and would later list the game as one they would like to see on a hypothetical Virtual Console platform for the Nintendo DSi, owing partially due to its real-time strategy interface. A sequel to the game, titled "Wizards", was in development for the Game Boy Advance, but was cancelled due to the lack of a publisher.
Document 15: Super Nintendo Entertainment System: While other companies were moving on to 32-bit systems, Rare and Nintendo proved that the SNES was still a strong contender in the market. In November 1994, Rare released Donkey Kong Country, a platform game featuring 3D models and textures pre-rendered on SGI workstations. With its detailed graphics, fluid animation and high-quality music, Donkey Kong Country rivaled the aesthetic quality of games that were being released on newer 32-bit CD-based consoles. In the last 45 days of 1994, the game sold 6.1 million units, making it the fastest-selling video game in history to that date. This game sent a message that early 32-bit systems had little to offer over the SNES, and helped make way for the more advanced consoles on the horizon.
