I have a question about Old SecuRom.

http://support.alcohol-soft.com/knowled … b+Channels

Subchannel includes Data Subchannel and Audio Subchannel, where a disc saves
additional information other than normal data and tracks.

Since not all CD-ROMs/ CD-RWs support subchannel, some game and music vendors save the "fingerprint information" in the two sub channels.
Therefore, if user wishes backup the disc, it is considered as failed if these data do not correctly backup.

The manufacturers that use such measure of CD copy protection include Sony's Securom ("fingerprint " has been saved in Data Subchannel), New Securom ("fingerprint" has been saved in Data and Audio Subchannels), LibCrypt (Sony's PlayStation) and LaserLock. The data saved in Subchannels includes 16bytes (such as Securom and New Securom) and 96bytes (LibCript).

Therefore, the performance of CD-ROM/ CD-RW can read the two Subchannels
include: a. Raw+96, b. Raw+16, c.Raw (the data on Subchannels are unreadable), d. none (both the data on Subchannels and normal bad blocks are unreadable).

http://www.gameburnworld.com/protections_securom.shtml

SecuRom being the first protections used commercially is also one of the oldest protections widely used. Developed by Sony Technologies. Unlike the SafeDisc protection, the SecuRom protection stores its digital ID in the SubChannel Data of the original CD. SecuRom protected CD's don't contain any unreadable sectors. During Sony DADC痴 mastering process an electronic fingerprint is applied onto the glass master which assigns a unique number to each individual CD. SecuRom is also used on some Playstation titles. For more information on how this protection was developed visit the SecuRom website

SECUROM:

Securom © Sony Corporation

Check for these files on the CD or in the installation dir:

CMS16.DLL
CMS_95.DLL
CMS_NT.DLL
Or check for this logo on the CD's inner ring:

There's a new version of Securom called Securom NEW (used in e.g. UT2003, V-Rally 2, Diablo II, Ground Control, Music 2000, Soulbringer). There are NO cms*.* files anymore and on some CDs there isn't even the DADC-logo.
The new Securom files are:

SINTF32.DLL
SINTF16.DLL
SINTFNT.DLL
They are copied to Windows system or temp directory during installation!

CloneCD , Alcohol, the Blindread/Blindwrite suite and DiscJuggler 3.x are programs being able to do perfect copies of Securom (Old) protected CDs. In opposite to Safedisc it's easy to do a 1:1 copy of a Securom protected CD - no unreadable sectors. Anyway this copy won't run in many cases. The reason is Securom doesn't use unreadable sectors to verify if the CD is original, it uses data stored in the CD P/Q-subchannel.

If you don't have hardware being able to read & write the 16 byte PQ subchannel data needed to do a perfect copy of securom protected CDs just do a 'normal' 1:1 copy of the CD using one of the burning programs here and use DAEMON Tools to play. Just enable the Securom emulation in DAEMON Tools and your copy will run like the original.

Do you know which sector there is "fingerprint ", "digital ID"?

Maybe you can find the answer in the generic securom patches?: http://www.cdmediaworld.com/hardware/cd … urom.shtml

I bought some disc and test it.

It seems that the Libcrypt is from 13500 to 18000 and 40500 to 45000 but the securom is different.

sarami, do you want the "Old Securom" or securom in any variation?
