quote: Originally posted by Clint L.A. if you use Clony to scan a PSX/2 *CD-ROM* game, it will not detect any protection...All it will say is that it's a PlayStation game, as there is no way to check wether a PSX game is protected with Libcrypt... ...if it does it's protected and you must write in RAW DAO-96, with all subs checked in the read, with also a 96 byte subs read and check "Do Not Repair Subchannel Data" in CCD write window.
Clint,- I tend to agree with your first point. I know what's involved to check for invalid data in the Q channel. I don't think Clony is that clever; in fact, I know it's not that clever because if you click the Kopiershutz tab and highlight "PSX/Libcrypt", the text says "ClonyXXL only detects PSX discs, not Libcrypt". So where do people get off saying that LibCrypt is detected?!
- On the second point I've quoted. Yes you must do a 96 byte P-W write as this ensures an uncorrected sunchannel write, essential to reproduce the LibCrypt protection which is erroneous data. Checking "Do Not Repair Subchannel Data" 'forces' this 96 byte write.
- Audio subs are not required for a PSX read, nor is a 96 byte read; the standard MMC 16 byte PQ read is all that's required i.e data subs.
I think it's time to make the point that audio subs are not essential for PSX backups. To insist otherwise or ignore the point or pass it off as harmless adds to the confusion. Audio subs actually have less to do with audio than other essential data in the subs. To state "audio subs as harmless" also ignores the advance made by SecuROM in the WC3 version, where, most Lite-on burners could not back it up if audio subs was set; my 24102B being one of those burners. If Sony can produce similar unreliability in PSX backups with an improvement in the protection we''ll see thousands of instant coasters overnight and hundreds of "WTF?" questions about PSX
