The Game Boy Color is an 8-bit handheld game console, manufactured by Nintendo, which was released in Japan on October 21, 1998, and to international markets that November. It is the successor to the Game Boy and is part of its product line. Compared to the original, the Game Boy Color features a color TFT screen rather than monochrome, a processor that operates twice as fast, and has four times as much memory. It retains backward compatibility with games initially developed for its predecessor. However, despite these improvements, reviewers consider the Game Boy Color an evolution rather than a revolutionary leap in handheld gaming technology.
