God of War 2 - PS2 - Previously Undiscovered Cheat Codes, Unlock everything, enable flicker

The first is the same previously undiscovered code I pulled from GoW1. Unlock everything at the main menu, and unlock/max all spells/items from the in-game pause menu. Must be entered on controller #2. L3, R2, L2, R2, R1, L2, R1, L1, R2, Tri, R2, Tri The second code is entered at the main menu, also on controller #2. L3, L1, L1, L1, L2, R1, X, R2, Triangle, R2, Triangle No idea what it&supposed to do, but the end result is that it makes the screen flicker a bunch. Epilepsy challenge run maybe. Looks way worse in-game than captured here, as the capture rate synced up fairly well with half the flickers.
