Ghost Mode on PS2
I was researching how to use Cheat Engine with PS2 games; I’ve learned how to modify in-game currency (or the equivalent) and can pull that off, but what about making the character invincible—meaning they can't take damage?
Also, is it the game itself or PCSX2 that has a security system against using codes? I ask because it worked perfectly for some games, while others were difficult.
