Your jak x have memory card glitch so it cant save what should you do?

i know how save it whithout messing up your game

so load your game after its loaded take the memory card out of the ps2.

then play this will disable the autosave and it wont be able to autosave.

when you whant to save it go to save file but put your memory card in before you save.

then press save game. after that take it out again and play on
