CRC/libsync errors

[razza]

Hi Guys, this is my first ever post so please be gentle with me.

I have copied about 10 of my PS2 games without any problem and they work perfectly on my newly chipped (messiah2) PS2, however 2 of my games are refusing to be copied.
One is 'Dynasty Warriors4', the other is 'SSX3'

The problem is retrieving the files from the CD to my PC, 'SSX3' waits until I have 99% of the disc copied then it develops a bad sector problem, 'Dynasty Warriors4' does the same but about half way through. The disks are clean and scratch free, according to 'ClonyXXL' they both have ' Libsync ' protection.
I have tried every DVD proggy out there (just about) and they all fail at recovering the full disk contents.
I cant find any in depth reference on how to recover the files or defeat the protection, could anyone advise me on what course of action I should take.
BTW the disks work perfectly in my PS2, in fact 'SSX3' is only 2 days old.
I know not all game copying is straightforward, and I'm willing to 'roll my sleeves up' to get working copies, any Ideas Guys?

Thanks in anticipation
Razza

I think you are reffering to 'Libcrypt' - a protection used on PS2 CD games - not DVD. No wonder it doesn't work. Use Alcohol 120%, place the disc in your CD-RW and use Alcohol 120% to copy. Make sure you select Playstation 2 as Datatype and burn away.
