This cheat disc, from the makers of Action Replay, features a whole list of codes for things like infinite ammo, infinite health, infinite items and includes codes to unlock items that are unobtainable in the game. Examples include Cardboard Box D and the Infinity Bandana. Cardboard box D is a transparent box, giving you a look at how Snake actually moves while in the box, or you could use it to crouch run like MGS4. The bandana is just an icon. Equipping it has no effect.
