Sega Master System / Mark III / Game Gear
When playing as JJ, go to any room that has a guard who passes in front of the computer console. Access the computer when the guard is in front of it, so that you are overlapping both the guard and the computer. Enter the suicide code (0000), and instead of dying, you will become invincible. NOTE: Once invincible, the button will not work, which means you will not be able to change characters.
To become invincible, in room (C,3), get halfway on the elevator so that J.J. is in the laser beam. Go up and down between floors. When J.J.'s power reaches 0, the floor will drop out and J.J. will be invincible. (This is difficult and may require several attempts.)
When you reach a dead end, shoot the wall in front of you up to 15 times to reveal a hidden room.
If you enter the suicide code in rooms D2 and G4 you will get a special message.
NOTE: To enable PAR codes on an American NTSC System start the game and then pause it. Attempting to access PAR at the title screen usually locks the game up.
