The Game Boy is a portable gaming device created by Nintendo. It features a 160x144 resolution 4 shade grayscale display, cartridge game system, stereo sound (though headphones), and controls similar to the already popular Nintendo Entertainment System. It was first released in Japan on April 21, 1989, in North American on July 31, 1989, and in Europe on September 28, 1990.



The Game Boy was reworked by Nintendo a few times to keep it relevant as it aged in the handheld market. Despite the changes to the look, the audio chip remained the same through each model.

The Game Boy was advertised with stereo sound, but the unit only has one speaker. However, headphones can be plugged in to hear stereo sound.
