Grand Theft Auto San Andreas error (PS2)?

iv done basically the same thing, but not the same result... cheat codes in games have the potential to be so buggy that they could render the game inoperable like yours. if you do use cheats, save a file before you use them, then add the cheats in. if there is a problem in the game then unfortunatly you would have to go back to that save. but at least you would know it wouldnt work. try experementing with wat cheats will do wat to the game, like good performance or bad system problem
