Help dumping unlicensed PS2 discs

[Enker]

I have 3 unlicensed PS2 discs: Swap Magic 3.6 CD & DVD, and a GameShark disc. All of these discs only dump about 6% before I get an unreadable sector error. None of the discs are scratched and they all stop at 6%, so they all must have some kind of protection. I've tried dumping them with all of my drives and none of them can dump more than 6%. Does anyone know what could be causing this to happen?

They ARE protected, leave them out.

[Enker]

I figured they were. So, discs with protection like this can't be dumped?

I have a same problem with my Code Breaker disc.

If they are CD's use CloneCD, use the same profile as is posted for SafeDisc for PC.

[Enker]

The CloneCD profile didn't help, it still won't dump the discs. One of mine is a DVD, so I think they all use the same weird protection. The discs seem to include retail game data, so they must do some trickery to boot on the PS2.

Scan the data side of the disc at high-resolution and post a pic somewhere. We might be able to get some idea's from that.

I don't have access to a scanner right now, but I can tell you that each disc has a small section outside of the ringcode section in the data area that is a different shade from the rest of the disc's data area. The Swap Magic discs also have a lot of little rings that run through the data area. Here's a page with a small picture of a Swap Magic disc.

Here's a page about how the discs work, maybe it can help?

I finally got access to a scanner, so here are the disc scans:

GameShark 2 V1.2 CD
Swap Magic 3.6 CD
Swap Magic 3.6 DVD

I always thought that those discs were impossible to properly burn/copy because they're pressed (at the factory, just like some content on a regular ps2 dvd, which isn't readable -- i might be saying a lot of shit, all i know is what've read here and there).

If those discs can be dumped, even though they're no interest to the Redump project, please let me know of a preservation-proof method. I have SM3.xx Pal and a Memorex (can't recall the version, but I believe it's from Codebreakers).

I haven't tried to dump with any tools in the Redump Guide, but back in the days I haven't had any success using dvd decripter, imgburn and anydvd (those were my tools, back then).
