Batman: Return of the Joker (1992) Cheats For Game Boy

1. Support Character (Robin)

   At the title screen, press Left, B, and Select together. The game will start with a different sound, confirming correct code entry. Now on every boss stage when you dip under 3 points of health while the boss exceeds 16, you'll receive support from Robin that will fly over the screen, dropping some health. This will only trigger once per boss.
