Balloon Fight GB is a color remake of Balloon Kid.
All features from Balloon Kid are still intact. The main new addition is that there is color. There is now also a world map, and the title screen and menu systems are slightly different. Through the world map, levels are given names, which were previously unknown since Balloon Kid did not give any names to areas or levels.
Balloon Fight GB is notoriously rare, and it was distributed via the Nintendo Power Flash cartridge, which is no longer supported by Nintendo. As such, copies of this game downloaded onto one of these cartridges can get high prices and rarely is ever sold. Due to the nature of this cartridge, the game would have had to been downloaded onto the cartridge before the service was discontinued.
This game is available today on the 3DS eShop as a Game Boy Color Virtual Console game. However, the game is only available through the Japan eShop, so 3DS owners in Europe and America cannot download the software.
After the Nintendo Power cartridge writing service was shut down, it was possible to order prewritten Nintendo Power cartridges with Balloon Fight GB over the phone, and these versions came with a fold-out manual and a large button with the game's box art, among other things.
