WTF? The prefered version of Action Replay Max is the one with the Max media player. That one will allow installation on all versions of ps2's. The one without will only allow installation on only fat ps2's. Codebreaker 8.1 or newer is good to use only up until SCPH-7500x. upon that model and newer, codebreaker will not work correctly. Gameshark sucks and don't even mess with it. It is a worthless cheat disc and even more worthless for any other task.
If you need help, post a question in the
forums, not my PM inbox. Thank you.
