Problem with disc: https://redump.info/disc/42666/

This is a clear case where 00:00:00 Track02 pregap causes audio data to be moved into the data track.

From previous discussion: /viewtopic.php?t=11429 … or-sector/

"If sync doesn't exist in the sector of mastering error, this sector shouldn't be descrambled. Because no sync = not a valid data sector."

However, DIC is descrambling these sectors. This is wrong.

Fixed: The data sector is descrambled when sync and mode is valid.

I don't have logs from: https://redump.info/disc/42648/. Usurper has them...

sarami, does it apply for Mode0 too?

Posted: **Tue Jun 06, 2017 7:36 pm**

It applies to mode 1 and 2.

There seems to be some inifite loop in function: OutputFsPathTableRecord:

pDirRec[*nDirPosNum].uiDirNameLen is 0 in my CD and it casues infinite loop

Posted: **Mon Jun 12, 2017 9:34 am**

Escaped 0 length.

Code: Select all

        if (pDirRec[*nDirPosNum].uiDirNameLen > 0) {
                                   :
                                   :
        }
        else {
            OutputVolDescLogA(
                "\t     Length of Directory Identifier: %u\n", pDirRec[*nDirPosNum].uiDirNameLen);
            break;
        }

Is 0 correct value? I want to look the *mainInfo.txt and *volDesc.txt

So I am dumping a new disc with SecuROM 4.85.07 trying to get proper subchannel information but the subIntention.txt from a dump with the May 11 2017 version differs by one line (one less entry) from the dump I got using the March 23 2017 version

During this time the /se changed to /ns, so maybe my input is different? If I should be using more new /n* options related to protection maybe I missed something.

input commands are
DiscImageCreator.exe cd G rt3d2sec510 4 /c2 /d8 /ns [new]
DiscImageCreator.exe cd G rt3d2upse 4 /c2 /d8 /se [old]

the .sub files hash identically and psxt001z output is identical, and seems to include reference to the sector that is missing in the latest version (MSF: 01:41:62)

Number of modified sectors: 15

Maybe the "?" means that the line at 01:41:62 should not be created and this is a fixed error in the newest version?
Just wanted to check so I don't submit something wrong to the db!
Thanks for this great tool

This one shouldn't be included (not SecuROM data)
