Super Game Boy
The Super Game Boy is a plug-in cartridge for the Super NES that allows Game Boy and black cartridge Game Boy Color games to be played on a television screen. It was released in 1994. The black-and-white games can be colorized by mapping colors to each of the four shades of gray making up the Game Boy's color palette. There are also special Super Game Boy labeled Game Boy games that contain custom palettes and borders that only show up when played on a Super Game Boy. A 1998 follow-up released only in Japan, the Super Game Boy 2, includes different default borders, different music for the credits, and a link cable port, enabling support for multiplayer gaming and the Game Boy Printer.
