Well, thx for the answer. On my CFW FERROX 4.82, the game was loading normally, but no cheats were activated. So, I changed it to a REBUG 4.82 CEX and made a conversion to DEX. Now the cheats seems to work, but when the first enemies appear (when Cole arrives in New Marais by the swamp), the game freezes. Any help ?By "It didn't work", what do you mean?
Does the game never start and gets stuck at a black screen? If so, your package is messed up or has bad codes.
Does the game play completely normal as if no cheats are activated? If so, you're installing the wrong package that has a different Game ID than yours.
