Hey,

I've been attempting to dump Datel's "Game Studio" for the PS2, an unlicensed game that seems to use weird tricks to bypass Sony's copy/licensing protections. More information about the game is available here:
http://www.nesworld.com/article.php?sys … ocketgames

The disc itself is a CD, and before using DiscImageCreator on a Windows 10 machine, using a Plextor 716UF USB drive bought for the occasion, I attempted to dump it with:
- an "HL-DT-ST DVD-ROM DUE0N (D.02)" (SATA drive built in my pizza box workstation), under Linux, both with DiscImageCreator and cdrdao
- a TSSTcorp CDDVDW SE-208DB (MF00) (Samsung branded USB drive) using Linux (same tools)
- an LG BE06LU10 Blu-Ray burner using Linux and Windows 10

The disc is very capricious and sometimes doesn't even get detected as a media by the OS. When it does, I can copy a few files from it, including the unobfuscated ROMs for the Game Boy games.

I've now uploaded the "dump" on Dropbox, although I'm guessing that it won't be usable:
https://www.dropbox.com/s/gxhu8opgmnxtk … o.zip?dl=0

Any ideas on what I should try to get this dumped as cleanly as possible?

Cheers

If it has a black bottom you probably can't dump it correctly.

If it has an indigo bottom try dumping with the /sf flag. Good chance it will have 4000 or so errors up front, but as long as it dumps twice with the same hash it's a good dump.

It does have an indigo bottom (although I would have called that blue). I'll have another go with /sf.

I used DICUI 1.18-net48 with the following generated command-line. Anything else I should be passing?

C:\Users\User\Downloads\DICUI_1.18-net48\net48\Programs\Creator\DiscImageCreator.exe cd D ISO\Game Studio\Game Studio.bin 8 /c2 20

Thanks

First of all, please use the latest release of MPF (that's the new name for DICUI) https://github.com/SabreTools/MPF here.
Second, as explained here: http://wiki.redump.org/index.php?title= … Protection
you'll have to add the /sf command manually before starting the dump.

Game Studio.bin 8 /c2 20 /sf

We can't dump all the unlicensed discs at the moment with but you can still try it if it's going to work with your disc.

Plextor: PX-W4012TU, PX-W5224TA, Premium, PX-716SA, PX-716A || LG GDR-8164B || Lite-On SOHD-167D
HP (Toshiba/Samsung): TS-H353A - Kreon FW || HP (Hitachi/LG): BH40N - crossflashed with LG BH16NS40 FW || Sony Optiarc AD-7280S

Indeed /sf did the trick, and I managed to dump the disc twice and get the exact same data.

I'll have to work at the submission now, but here's the surprisingly small archive that contains the dump directory:
https://www.dropbox.com/s/svi3v8szxqpiw … 9.rar?dl=0

I've used RAR to compress it so that there's some recovery records.
