Created by game designer Gunpei Yokoi, the product derived its name from its featuring a single game as well as a clock on a LCD screen. The models from 1981 onwards featured an alarm in addition. It was the earliest Nintendo video game product to gain major success. The units are based on a 4-bit CPU, from the Sharp SM5xx family, that include a small ROM and RAM area and an LCD screen driver circuit, although, prior to its simulation in MAME, there was a misconception in that every unit used a custom ASIC instead of a proper microcontroller. The series sold a combined of 43.4 million units worldwide.</systemDescription> <systemDescriptionSource>https://en.wikipedia.org/wiki/Game_%26_Watch</systemDescriptionSource> <systemManufacturer>Nintendo</systemManufacturer> <systemReleaseYear>1980</systemReleaseYear> <systemReleaseDate>1980-04-28</systemReleaseDate> <systemReleaseDateFormated>April 28, 1980</systemReleaseDateFormated> <systemHardwareType>Portable</systemHardwareType> <systemCoverSize>4-3</systemCoverSize> <systemColor>8DA6AD</systemColor> <systemColorPalette1>C4353D</systemColorPalette1> <systemColorPalette2>C2904A</systemColorPalette2> <systemColorPalette3>853641</systemColorPalette3> <systemColorPalette4>4C301C</systemColorPalette4> </variables> <language name="sv_SE"> <variables> <systemHardwareType>Bärbar</systemHardwareType> </variables> </language> </theme>
