The SFO file is used by the PSP System in order to give details about the loaded game to the operating system. These details give the firmware of the PSP system the necessary information to determine whether or not to update the firmware, the title of the game, the rating of the game, the disc version, and the region code of the title. All this information together gives the system the ability to decide how to play or whether to play the game.
