3540 or 3652? Does it mean there is a sector with incorrect length somewhere? I've thought we decided to stop the descrambling in such cases?

It's the same as http://redump.org/disc/45432/ and http://redump.org/disc/70481/

+3652 offset for the user area due to pregap mastering issue.

2,628

But how to understand which area (or which sector?) has the offset 3540 and which one has the offset 3652?

2,629

I moved the scrambled sector to _maininfo.txt
LBA 0 to 4 has offset 3540 and LBA 6 to 10 has offset 3652.

Hi, I have a LibreDrive that works with dumping CDs with DIC. My problem is not with the inability to read high positive offset discs as I know that that is unfixable as far as DIC goes, but that I have four discs that I have dumped repeatedly, namely these four:

http://redump.org/disc/17354/
http://redump.org/disc/3857/
http://redump.org/disc/3858/
http://redump.org/disc/3859/

and they work as far as getting the correct lead-out, but only half of the time. I have tried with my copy of Shining Force III Scenario 3, and that does not seem to want to work at all with this "multiple dump" method, but I'm not exactly sure as to why.

On another note, all the mainInfo data is incorrect, and this is for all discs (especially as far as the header goes). Verifiably, the data in the disc images is correct, only the mainInfo.txt is wrong.

Everything is contained in these three archives:

If you want to get a ton of dumps done and ready for upload, never batch dump without tagging. You will leave yourself with a myriad of untagged dumps and it will drive you nuts.

Do you mean 00:02:00 to 00:02:04 and not 00:00:00 to 00:00:04 in pregap? But that means sector 5 is of incorrect length and the descrambling should be stopped, like http://redump.org/disc/39378/ or http://redump.org/disc/34036/ ? We only ignore such issues for the first pregap (sectors -150 to -1) - Gulf War and Lip 3 cases - when the redump image itself has a constant sector length and a constant offset.

I don't understand why 00:00:00 to 00:00:04 should be read. 00:00:00 to 00:00:04 also has offset 3540?
Sangokushi4 (also gulfwar, lip3) have the duplicate bytes of 00:01:74 (last 448bytes). If 3540+112 bytes are shifted from LBA 0, 00:00:00 to the end sectors are descramled correctly.

As far as seeing your comment of these dumps, another coding is needed.

Nope, my question was if you mean LBA 0 = 00:02:00 or LBA 0 = 00:00:00.

But sometimes the desync is in the pregap. For example, on +588 and +1176 US-mastered Saturn discs there are duped sectors in pregap, 00:00:00 has the offset +0 for these discs, so it is important to check the pregap sectors.

LBA 0 = 00:02:00

added checking only (output to _disc.txt)
http://www.mediafire.com/file/eq80y20l9 … st.7z/file

like this (test disc is T-8106G). You can confirm the duplicated sync.

Hi Sarami,

The dumper for this CD-i disc has dumped it multiple times and it hashes the same, but is throwing some non-C2 errors:

http://forum.redump.org/topic/31204/phi … s-of-evil/

Maybe worth a look?
