I'm pretty sure I've got an old DMS3.0 installed in my ps2 phat. Anyway, I've got the Action Replay (retail) disc and it boots up just fine. But, when I pop in a backup, it tells me there isn't a disc in the system. My question is, is there any way to use both Action Replay and backup discs? I'm even willing to get another PS2 and get a different mod chip or try anything else. Any help will be greatly appreciated.
