It was released in Japan on , in North America on , and in Europe on . It is the first handheld console in the Game Boy line, and was created by Gunpei Yokoi and Nintendo Research & Development 1—the same staff who had designed the Game & Watch series as well as several popular games for the Nintendo Entertainment System. Redesigned versions were released in 1996 and 1998, in the form of ''Game Boy Pocket'', and ''Game Boy Light'' (Japan only), respectively. The Game Boy is Nintendo's second handheld system following the Game & Watch series introduced in , and it combined features from both the Nintendo Entertainment System and Game & Watch.〔 It was originally bundled with the puzzle game ''Tetris''. As part of the fourth generation of gaming, the Game Boy competed with the Sega Game Gear, Atari Lynx, and the TurboExpress. Despite these other handheld consoles, the Game Boy was a tremendous success. The Game Boy and its successor, the Game Boy Color,〔 have both combined sold 118.69 million units worldwide. Upon its release in the United States, it sold its entire shipment of one million units within a few weeks.〔Kent 2001, p. 416. "According to an article in ''Time'' magazine, the one million Game Boys sent to the United States in 1989 met only half the demand for the product. That allotment sold out in a matter of weeks and its black and white (except for Konami/Factor 5 games and ''SeaQuest DSV,, was shown in color like the Game Gear version."〕 ==Hardware== The Game Boy has four operation buttons labeled "A", "B", "SELECT", and "START", as well as a directional pad.〔Owner's Manual, p. 5. "(12) Operation buttons — The controls for playing games. (See game manuals for button functions.)"〕 There is a volume control dial on the right side of the console and a similar knob on the left side to adjust the contrast.〔Owner's Manual, pp. 4–5. "(5) Volume dial (VOL) — Adjusts the sound volume…(7)Contrast adjustment (CONTRAST) — Adjusts the contrast of the display."〕 At the top of the Game Boy, a sliding on-off switch and the slot for the Game Boy cartridges are located.〔Owner's Manual, pp. 3–4. "(3) Game Pak slot — Insert the Nintendo GAME BOY Game Pak here. (See page 7 for instructions on inserting Game Pak)"〕 The on-off switch includes a physical lockout to prevent users from either inserting or removing a cartridge while the unit is switched on. Nintendo recommends users leave a cartridge in the slot to prevent dust and dirt from entering the system.〔Owner's Manual, p. 10. "To avoid dust and dirt getting in the Game Boy unit, always leave a Game Pak inserted when not in use."〕 The Game Boy also contains optional input and/or output connectors. On the left side of the system is an external 3.5mm x 1.35mm DC power supply jack that allows users to use an external rechargeable battery pack or AC adapter (sold separately) instead of four AA batteries.〔Owner's Manual, p. 4. "(2) External power supply jack — You can connect a Rechargeable Battery Pack (sold separately) for longer play."〕 The Game Boy requires 6 V DC of at least 150 mA. A 3.5 mm stereo headphone jack is located on the bottom side of the console which allows users to listen to the audio with the bundled headphones or external speakers.〔Owner's Manual, p. 5. "(10) Headphone jack (PHONES) — Connect the stereo headphones that come with the GAME BOY to enjoy the impressive sounds of games without disturbing others around you...."〕 The right-side of the device offers a port which allows a user to connect to another Game Boy system via a link cable, provided both users are playing the same game.〔Owner's Manual, pp. 4, 8. "(4) Extension connector (EXT CONNECTOR) — Connects to other GAME BOY…Do not insert different games in the interconnected Game Boys."〕 The port can also be used to connect a Game Boy Printer. The link cable was originally designed for players to play head-to-head two-player games such as in ''Tetris''. However, game developer Satoshi Tajiri would later use the link cable technology as a method of communication and networking in the popular ''Pokémon'' video game series. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Game Boy」の詳細全文を読む スポンサード リンク
