Borders...
	Grobda...
	Invulnerable...

If you are playing either SUPER PAC-MAN, GAPLUS, GROBDA, or MAPPY, pause during game play. Now, press the directional button in any direction to reveal 2 special borders where the score count is. If you don't like them, simply press the directional button until you are rid of it. NOTE: This is best experienced with the Simulated Arcade Mode, and will not work on Vertical Mode.

At the Grobda screen hold L2+L1+R1+R2 and press START.

Make your helicopter invulnerable. At loading screen after given mission orders press and hold L1+L2+R1+R2 for entire load time, CHEAT will appear.
