Many Game Boy emulators offer at least some of the special features of the Super Game Boy, a special cartridge for the SNES released in 1994. This feature would not be seen in Nintendo handhelds outside Japan until the Game Boy Advance SP. In Japan, a special edition of Game Boy Pocket, called the Game Boy Light, added a front light to the screen. A revision called the Game Boy Pocket was released in 1996, offering a more compact body and a better screen. The original model has a monochrome display. The Game Boy is an 8-bit, fourth-generation handheld console released by Nintendo in 1989.
