The Game Boy Color (ゲームボーイカラー, Gēmu Bōi Karā") is Nintendo's successor to the 8-bit Game Boy handheld game console, and was released on October 21, 1998 in Japan, November 19, 1998 in North America, November 23, 1998 in Europe and November 27, 1998 in the United Kingdom. It features a color screen and is slightly thicker and taller than the Game Boy Pocket. As with the original Game Boy, it has an 8-bit processor. The Game Boy and Game Boy Color combined have sold 118.69 million units worldwide.

History

The Game Boy Color was a response to pressure from game developers for a new and much more sophisticated system of playing, as they felt that the Game Boy, even in its latest incarnation, the Game Boy Pocket, was insufficient. The resultant product was backward compatible, a first for a handheld system, and leveraged the large library of games and great installed base of the predecessor system. This became a major feature of the Game Boy line, since it allowed each new launch to begin with a significantly larger library than any of its competitors.

Launch titles

• Centipede
• Game and Watch Gallery 2

The processor, which is a 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. The Game Boy Color also has three times as much memory as the original (32 kilobytes system RAM, 16 kilobytes video RAM). The screen resolution was the same as the original Game Boy, which is 160x144 pixels.

The Game Boy Color also featured an infrared communications port for wireless linking. The feature was only supported in a few games, however, and the infrared port was dropped for the Game Boy Advance and later releases. The console was capable of showing up to 56 different colors simultaneously on screen from its palette of 32,768 (8x4 colour background palettes, 8x3+transparent sprite palettes), and could 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 were given separate color schemes, and in the 10-color modes the sprites were further split into two differently-colored groups; however, as flat black (or white) was a shared fourth colour in all but one (7-color) palette, the overall effect was that of 4, 6 or 8 colours. This novel method of upgrading the color count did result in graphic artifacts in certain games; for example, sometimes a sprite that was supposed to meld into the background would be colored separately, making it easily noticeable.

Cartridges

Games that are designed specifically for the Game Boy Color are housed in clear-colored cartridges, and will not function in an earlier Game Boy or the Super Game Boy (or will simply display a warning message and refuse to play). Games that are designed for the Game Boy Color, but which also include backwards-compatibility with the previous Game Boy systems, have a similar design to the original grey Game Boy cartridges, but are colored black for identification. The European and American releases of Pokémon Yellow and Pokémon Gold and Silver feature different-colored cartridges, although they are technically identical to the standard black ones. Game Boy Color Cartridges will function correctly when used in a Game Boy Advance or Game Boy Advance SP system. No cartridges made for any system earlier than a Game Boy Advance will function in the Nintendo DS or Nintendo DS Lite, and nothing earlier than a DS card will function in a Nintendo DSi, Nintendo DSi XL, or Nintendo 3DS.

Color palettes used for original Game Boy games

When playing an original Game Boy game on a later system, the user can choose which color palette is used. This is achieved by pressing certain button combinations, namely either A or B (or neither) and a direction key while the Game Boy logo is displayed on the screen.

Directional pad	Action button
	None	A	B
Up	Brown	Red	Dark brown
Down	Pastel mix	Orange	Yellow
Left	Blue	Dark blue	Grayscale
Right	Green	Dark green	Inverted

• 
  Illustrated color-samples of the palettes for the different key-combinations. Any color crossed out will be present in palette RAM, but rendered as transparent.

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

In addition, 93 Game Boy games have a special palette that is enabled when no buttons are pressed. Any game that does not have a special palette will default to the dark green (Right + A) palette. Notable games that do have preset palettes are Metroid II: Return of Samus, Kirby's Dream Land 2, Super Mario Land, Tetris, and the Wario Land series. The default palettes are stored in a database within the internal boot ROM of the GBC, and not the game cartridge itself.

Super Game Boy titles will work too. Despite compatibility with Super Game Boy titles, the Game Boy Color will not recognize the coloring header for Super Game Boy titles which have a color graphics system of its own.

Hi-Color Mode

The Hi-Color mode is a mode used by the Italian company 7th Sense s.r.l., which displays more than 2000 colors on the screen. The games with the Hi-Color mode are: The Fish Files, The New Addams Family Series.

Games

Main article: List of Game Boy Color games

The last Game Boy Color game released in Japan that was also compatible with the Game Boy and Super Game Boy was From TV Animation - One Piece: Maboroshi no Grand Line Boukenhen! (July 2002). This gave the original Game Boy (1989–2002) one of the longest continuous lifespans of any console, only beaten by the Atari 2600 (1977–1992), Neo-Geo AES/MVS (1990–2004) and the NES (1983 - 2003). Its North American lifespan was shorter though, as the last Game Boy and Super Game Boy compatible game released there was Dragon Warrior Monsters 2 (September 2001). The last North American Game Boy Color-exclusive game, however, was Harry Potter and the Chamber of Secrets. Although it was released on different consoles, the Game Boy Color featured an exclusive version.

With the release of the Nintendo 3DS, Nintendo has announced that the Virtual Console service will also be available for the 3DS and will allow players to play games from the Game Boy and Game Boy Color.

Sales

The Game Boy and Game Boy Color combined have sold 118.69 million units worldwide, with 32.47 million units in Japan, 44.06 million in the Americas, and 42.16 million in other regions.
