Gun (PlayStation 2)
Document the two unused cutscenes in the debug menu.
Applying the below code will enable a debug mode that opens two extra options in the OPTIONS menu while in-game. While the code is active, press R3 + D-Pad Up to enable it, and R3 + D-Pad Down to disable it. Make sure you only enable it some time after the opening logos.

The CHEATS menu doesn't work in this port. GUN opens a level select menu and a cutscene viewer.
