The Game Boy is a handheld game system by Nintendo which has interchangeable game cartridges (sometimes called Game Paks) unlike its predecessor, the Game & Watch line of handheld LCD games. The system had similar controls to an NES and a grayscale dot-matrix screen. The original model was released in 1989, and received revised models including the Game Boy Pocket in 1996 and the Game Boy Light in 1998. It was succeeded by the Game Boy Color.
Balloon Kid was released for the Game Boy in 1990, featuring a new version of the Balloon Trip gameplay style first seen in the NES version of Balloon Fight. This game later received a Game Boy Color enhanced remake called Balloon Fight GB, which was also playable without color on the original hardware. Although the original was never released in Japan and the remake never released internationally, both versions were compatible in the VS. Play mode if connected with a link cable.
There were also two other games on the system with minor Balloon Fight references:
- Game Boy Camera (February 21, 1998) - Various sound effects and music from Balloon Kid are repurposed for the interface. This is the first instance of the Balloon Fight series being referenced in an unrelated game.
- Game & Watch Gallery 3 (August 4, 1999) - A non-playable demonstration of the Balloon Fight Game & Watch can be unlocked for the in-game museum.
