Unfortunately the cheats in this game (RE4) don't work perfectly. There are also problems with ammunition which, with constant cheat enabled, the value increases and decreases by one point without reason. It also happens to me that as soon as I pick up some other jet (herb or grenade), the objects that had 535 return to their original value. I would say that the modification of the savegame would be the top also because we must always disable everything otherwise the game in some points goes very slow. A pity, I currently give up. With RE0 and RE1 all this does not happen and the cheats are a marvel, today I finished the first Resident Evil successfully and with the cheats activated, also at the end of the game he scored 0 saves. Too bad for Resident Evil 4, I hope someone creates perfect cheats!
