Balloon Fight GB

Balloon Fight GB is a re-release of Balloon Kid, first as a standalone cart and then through the Nintendo Power GB Memory service. Save features, a world map, Game Boy Color, and Super Game Boy support were added.

Alternative Super Game Boy Border
Immediately after booting up, and while the screen is white, hold any button on either the first or second controller, and an alternative border will load. The MLT_REQ command is set to directly after starting up to allow the second controller to enable the border. The bit is set to directly before the picture is sent. Enabling the Super Game Boy two-player mode was done solely for this purpose.
