Pal to Jap patches....?

From the info you've provided, you would need to use CDRWin and patch with Universal patcher. All unprotected games will play in my experience. EA games with protection are unplayable on the SCPH 15000 with this modchip system. I've got nothing to work with CloneCD on the 15000 because it does need the Uinversal Patcher to boot behid the Utility Disk.

If all CDs fail at the same % point when copying, and without knowing your circumstances, this looks like an expired demo copy or a cracked serial. If you're properly licnsed for CDRWin, then how compatible is your reader/burner?
