IN the recent stuff of "crashes by saves" i have made my own.. the diffrence is this is for Grand Theft Auto Liberty City Stories.
when loaded it can possibly change version number to 1.0 and downgrader..
This is the same h.bin the 2.0 downgrader has. This basically runs it when u go to the h.bin this runs from inside the game. Not the PSP Menu. Go to GTA and go to load game and pick this and it will run.
