Tom Clancy’s Ghost Recon Advanced Warfighter 2 (GRAW 2) is a shooter developed by High Voltage Software and published for the PSP in 2007. Edward Kirk found out that in the final game there are still some unused options that are usually hidden.
This game contains a number of debug options and a level select which, when enabled, turn it into a “Pre-Certification” version. The released game contains a file called Game-txt, which can be edited to enable the debug menu and other options used to test a game.
The debug has a number of different options which affect the game, such as …
… wireframe mode. Although the Game.txt file does identify the enabling of cheats, the features found so far are definitely for debugging and testing, rather than just making it easier to get through the game.
