Not so sure that is entirely true in all cases. In the particular case of a Jap PS2 and Winning Eleven 5, with modchip.com mod chip and PS2 Utility Disk for booting, the CloneCD method doesn't work unless it is booted first with the original game (of course). To make it work as a backup only, I had to patch it with the Universal Patcher (by Paradox from Megagames.com) and that meant using CDR-WIN to stage the BIN file.
