LBA 0 to 4 has offset 3540 and LBA 6 to 10 has offset 3652.
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 https://redump.info/disc/39378/ or https://redump.info/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.

Code: Select all

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:

/viewtopic.php?t=26150 … s-of-evil/

Maybe worth a look?

What does this mean in human language and is it good to submit to redump or is the disc bad?
