Hack description

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.
