The Super Game Boy 2 is the successor to the Super Game Boy, and released exclusively in Japan on January 30, 1998. It was made as a response to complaints from Japanese Pokémon players who could not trade Pokémon with their friends because they only owned an original Super Game Boy, which lacks a link port.
In terms of features it was very similar to the function of the original Super Game Boy. The casing was a much sleeker design, made of transparent blue plastic. A game link port and LED power light were added to the hardware, and the firmware gained 5 new screen border graphics that could be displayed while playing a game. Outside of the aformentioned differences, it was essentially the same as its predecessor.
