The first handheld game console from Nintendo, it is white with the same controls as the NES, except the B and A Buttons are pink, and the Select and Start Buttons are gray. To turn on the system, slide the switch on the top. Requires two AA batteries. The game pak is much smaller than the NES, and is shaped like a square. It will also fit in later Game Boy systems. The original Game Boy only has a black and white screen, like a calculator and other electronics. Game Boy games carry between 512 kilobits and 8 megabits, and only contain grayscaled colors.
The Game Boy was released in Japan on April 21, 1989, in North America on July 31, 1989, in Europe on September 28, 1990, and in South Korea late in 1990 as the Mini Comboy (which is almost completely identical to the original design, but with the words "Mini Comboy" added). Before the system itself ended, a new Game Boy pocket was introduced in 1996 at a retail price of $59.95. There was also an extremely rare Toyota Game Boy design only seen in Japan, which of course, was also not available in stores back then. The original Game Boy was replaced by the Game Boy Color in 1998.
For games that require two players, a Game Link Cable was also available. However, this may also require another copy of the same cartridge for the video game being played. The first game to support multiplayer mode was Tetris, which was released on the same date as Super Mario Land.
