Batman Returns is an action beat 'em up game for the Nintendo Entertainment System. The game is based on a movie with the same title.

This hack gets rid of the numerous and particularly nasty copy control mechanisms of the game.

The point is that other romhackers could use this hack as a base, and thus be able to modify the title screen without fear of triggering the copy control mechanisms.

The copy protection in this game could:
- double the damage dealt to the player
- make sure the exit of stage 3-1 remains closed, making the stage loop forever
- hand out unvalid passwords
- make sure valid passwords could not work

A total of 7 pieces of code were disabled. See the readme file for more info.
