I Want Cheats !!
 

I have Playstation 2 Version 4 with messiah chip in it and neither Gameshark nor Action Replay nor Codebreaker are working (All burned). What could be the problem ?

Bad burns??? Just guessing.

I meant that the codes in these programs don't work. I choose in the menu the game that I want and the cheats. I put the game in the console and it works but nothing has changed. The codes don't work, not the program itself.

use an origanal cheat disk then the codes will work
never tryed using a backup
