The Game Boy Color [lower-alpha 1] (commonly abbreviated as GBC) is a handheld game console, manufactured by Nintendo, which was released in Japan on October 21, 1998 [6] and to international markets that November. It is the successor to the Game Boy and is part of the Game Boy product line.


The GBC features a color screen rather than monochrome, but it is not backlit. It is slightly thicker and taller and features a slightly smaller screen than the Game Boy Pocket, its immediate predecessor in the Game Boy line. As with the original Game Boy, it has a custom 8-bit processor made by Sharp that is considered a hybrid between the Intel 8080 and the Zilog Z80. [7] The American English spelling of the system's name, Game Boy Color, remains consistent throughout the world.

The Game Boy Color is part of the fifth generation of video game consoles. The GBC's primary competitors in Japan were the grayscale 16-bit handhelds, SNK's Neo Geo Pocket and Bandai's WonderSwan, though the Game Boy Color outsold them by a wide margin. SNK and Bandai countered with the Neo Geo Pocket Color and the WonderSwan Color, respectively, but this did little to change Nintendo's sales dominance. With Sega discontinuing the Game Gear in 1997, the Game Boy Color's only competitor in the United States was its predecessor, the Game Boy, until the short-lived Neo Geo Pocket Color was released in North America in August 1999. The Game Boy and the Game Boy Color combined have sold 118.69 million units worldwide making them the third-best-selling system of all time. [8] [9]

On March 23, 2003, the Game Boy Color was discontinued, shortly after the release of the Game Boy Advance SP. Its best-selling game is Pokémon Gold and Silver, which shipped 23 million units worldwide. [10] [11]


Development for the Game Boy Color began in 1996, [12] when Nintendo received requests from game developers for a more sophisticated handheld platform, who said that even the latest iteration of the original system, the Game Boy Pocket, had insufficient hardware.[ citation needed ] Nintendo developed the console concurrently with its successor, the Game Boy Advance (which was codenamed “Atlantis” at the time). The resultant product was backward compatible with all existing Game Boy software, a first for a handheld system, allowing each new Game Boy product launch to begin with a significantly larger game library than any of its competitors.

On March 23, 2003, the Game Boy Color was discontinued. [8]

The processor, which is a Zilog Z80 workalike made by Sharp with a few extra (bit manipulation) instructions, has a clock speed of approximately 8 MHz, twice as fast as that of the original Game Boy. [lower-alpha 2] The Game Boy Color has three times as much memory as the original (32 KB system RAM, 16 KB video RAM). The screen resolution is the same as the original Game Boy at 160×144 pixels.

The Game Boy Color features an infrared communications port for wireless linking. The feature is only supported in a small number of games, so the infrared port was dropped from the Game Boy Advance line, to be later reintroduced with the Nintendo 3DS, though wireless linking would return in the Nintendo DS line using Wi-Fi. The console is capable of displaying up to 56 different colors simultaneously on screen from its palette of 32,768 (8×4 color background palettes, 8x3+transparent sprite palettes), and can add basic four-, seven- or ten-color shading to games that had been developed for the original 4-shades-of-grey Game Boy. In the 7-color modes, the sprites and backgrounds are given separate color schemes, and in the 10-color modes the sprites are further split into two differently-colored groups; however, as flat black (or white) was a shared fourth color in all but one (7-color) palette, the overall effect is that of 4, 6, or 8 colors. This method of upgrading the color count results in graphic artifacts in certain games; for example, a sprite that is supposed to meld into the background is sometimes colored separately, making it easily noticeable. Manipulation of palette registers during display allows for a rarely used high color mode, capable of displaying more than 2,000 colors on the screen simultaneously. [17]

For dozens of select Game Boy games, the Game Boy Color has an enhanced palette built-in featuring up to 16 colors—four colors for each of the Game Boy's four layers. [18] If the system does not have a palette stored for a game, it defaults to the "Dark green" palette. However, at power-up, one of 12 built-in color palettes is selectable by pressing a directional button and optionally A or B while the Game Boy logo is present on the screen.

These palettes each contain up to ten colors. [19] In most games, the four shades displayed on the original Game Boy translate to different subsets of this 10-color palette, such as by displaying movable sprites in one subset and backgrounds in another. The grayscale (Left + B) palette produces an appearance similar to that experienced on the original Game Boy, Game Boy Pocket, or Game Boy Light.

Game Boy Color color palette reference

A few games used a scan-line color switch technique to increase the number of colors available on-screen to more than 2,000. This "Hi-Color mode" was used by licensed developers including 7th Sense. Some examples of games using this technique are The Fish Files, The New Addams Family Series, and Alone in the Dark: The New Nightmare. [17] Cannon Fodder uses this technique to render full motion video segments in the introduction sequence, ending, and main menu screen. [20]

Game Boy Color exclusive games are housed in clear-colored Game Pak cartridges. [21] They are shaped differently than original Game Boy Game Paks. Notably, these cartridges lack a notch that prevented the original Game Paks from being removed while the original Game Boy was powered on due to a plastic piece attached to the power switch, which would slide over the notch, locking a cartridge inside the system during gameplay (although some special cartridges like Kirby Tilt 'n' Tumble [22] do include this notch). The lack of this notch keeps original Game Boy systems loaded with Game Boy Color cartridges from powering on. Similarly, Game Boy Pocket, Super Game Boy, Super Game Boy 2, and Game Boy Light will power on when loaded with a Game Boy Color cartridge but will refuse to load the game and will display a warning message stating that a Game Boy Color system is required. This same warning message can be viewed on an original Game Boy as well if the piece that slides into the notch is cut out of the Game Boy. Some Game Boy cartridges such as Chee-Chai Alien [23] [24] and Pocket Music [25] cannot be played on Game Boy Advance and Game Boy Advance SP systems. When inserted and powered on, these systems will exhibit a similar error message and will not load the game. Black cartridges are backwards compatible, playable on the original Game Boy.

Model colors

The logo for Game Boy Color spells out the word "COLOR" in the five original colors in which the unit was manufactured: Berry (C), Grape (O), Kiwi (L), Dandelion (O), and Teal (R).

Another color released at the same time was "Atomic Purple", made of a translucent purple plastic similar to the color available for the Nintendo 64 controller. Other colors were sold as limited editions or in specific countries.


Due to its backward compatibility with Game Boy games, the Game Boy Color's launch period had a large playable library. The system amassed a library of 576 Game Boy Color games over a four-year period. While the majority of the games are Game Boy Color exclusive, approximately 30% of the games released are compatible with the original Game Boy.

Tetris for the original Game Boy is the best-selling game compatible with Game Boy Color, and Pokémon Gold and Silver are the best-selling games developed primarily for it. The best-selling Game Boy Color exclusive game is Pokémon Crystal .

The last Game Boy Color game ever released is the Japanese exclusive Doraemon no Study Boy: Kanji Yomikaki Master, on July 18, 2003. The last game released in North America is Harry Potter and the Chamber of Secrets , released on November 15, 2002. In Europe the last game released for the system is Hamtaro: Ham-Hams Unite! , on January 10, 2003.

The Game Boy and Game Boy Color were both commercially successful, selling a combined 32.47 million units in Japan, 44.06 million in the Americas, and 42.16 million in other regions. [8] [9]

In 2003, when the Game Boy Color was discontinued, the pair was the best-selling game console of all time. Both the Nintendo DS and PlayStation 2 have since outsold the Game Boy and Game Boy Color, and thus the pair are now the third-best-selling console and the second-best-selling handheld of all time.

The Nintendo 2DS is a handheld game console produced by Nintendo. Announced in August 2013, the device was released in North America, Europe and Australia on October 12, 2013. The Nintendo 2DS is an entry-level version of the Nintendo 3DS which maintains otherwise identical hardware, similar functionality, and compatibility with software designed for the Nintendo DS and 3DS. However, the 2DS is differentiated by a new slate form factor rather than the clamshell design used by its precursors and by lacking the Nintendo 3DS's signature autostereoscopic 3D display. The 2DS was sold concurrently with existing 3DS models as an incentive to expand the market for Nintendo 3DS games; former Nintendo of America president Reggie Fils-Aimé stated that the 2DS was primarily targeted towards younger players, whom Nintendo had previously advised not to use the 3D functionality on the 3DS due to potential eye health concerns. The Nintendo 2DS's successor, the New Nintendo 2DS XL, was launched in 2017.
