PS-X-Change v2.0 is released ! The hottest item for the past couple of months finally get a major upgrade. Still the ultimate boot disk for PSone and Playstation, it also is afully compatible with Action Replay codes cheat device. It allows you to play import/backup games WITHOUT FITTING A MOD CHIP. No more invalidating your warranty, just insert this disk and when prompted, swap for you import/backup and away you go.
So there you go guys........... works without chipping your PSone
