Debug mode(basically the CW cheat for the psp, but for this single game)-pause game and hold L1 and R2, then press up, triangle, down, X, left, right, circle. Then release shoulder buttons and slowly press L1, R1, L2, R2, wait a moment, unpause and hit L2+R2. This debug mode will have all items, and a ton of junk. You can even set a motionless enemy in front of you and kill him. Only thing is, once you use one thing on it, it turns off and you have to re-enter the cheat
