4 discs are "Parallel Track Path", not "Opposite Track Path". I think "LayerZeroSector" number is layerbreak.
e.g.

========== SectorLength ==========
    LayerZeroSector: 1708076 (0x1a102c)
          :
          :
========== SectorLength ==========
    LayerOneSector: 2079572 (0x1fbb54)
    LayerAllSector: 3787648 (0x39cb80)

L0 is 0 - 1708075 (Length is 1708076). L1 is 1708076 - 3787647 (Length is 2079572).

Makes sense, thanks for clarifying

@sarami, TeamEurope dumped 4 DVD9's but we can't find the correct LayerBreak values in the disc log (logs attached).

If it's supposed to be the "LayerOneSector" number, then 3 of the 4 discs have an odd number. Can this be correct? The new disc form only accepts even numbers.

The last 4 submitted dumps all have even numbers:
http://redump.org/disc/65955/
http://redump.org/disc/65956/
http://redump.org/disc/65957/
http://redump.org/disc/65958/
so I dont know what's wrong.

According to this website, it's not: https://ogdb.eu/index.php?section=game&gameid=18617

Please provide some proof

We are seeing an influx of dumps that are done with ASUS drives. These drives do not support lead-out overreading. How do you warrant that there are no missing bytes in the last sectors? Does the program prevent dumping such discs?

We already spotted this. Guess EA is creating images with matching crc32.

Comments:
Title on disc label: Blaze MP3 DC: MP3 Player for Dreamcast

Not true.. The box and discs all say "Use MP3 Audio CD's on Your Dreamcast"
The front of the box does have "MP3 Player for Dreamcast" also, but "Use MP3 Audio CD's on Your Dreamcast" is more prominently displayed, so there's no point in adding it to comments.

If /sf is used, the protection is detected and there are C2 error sectors with invalid sync + msf + mode, then the sync + msf + mode should be generated and the rest replaced with 0x55. The mode should match the rest of the track.

If there is no C2 error on a sector, it should never be modified, also not if /sf is used and a protection is detected.

iR0b0t doesnt want yellow dumps in the datfile.

If you change them to yellow, people will discard the dumps and this will hurt preservation. It will not motivate people in any way to buy them and redump them. We're already doing the best we can.

If all these need redumped, shouldn't the statuses be changed to yellow?

Let's not do this.. most dumps will stay forever yellow then. The redumped dumps aren't really better, they just have different data in the read error sectors.

Another idea:
Why to replace sector with C2 errors with 0x55 when you could just replace specific bytes with some pattern and leave the good data as is?

Another question:
What if there's a sector with few bits set to 1 in C2 and it's easily correctable by ECC? Should it be replaced with 0x55, fixed or left as is?

A protection is detected with a particular range. The C2 errors within that range are the trigger for replacing sectors with 0x55. There is no good data there.

There's a good data there - bytes which have 0 in C2 map. Bad bytes are marked with 1 in C2 map. I know where this goes - all discs with any protection should be reripped, including safedisc. For me personally 0x55 is fine since it doesn't involve all the hassle. If someone wants pure image he can generate IPS patch and store it in DB.

Yes there's 312 error bits out of 2352 for each sector that are marked 1? But we don't know if these C2 pointers are in any way reliable or of the rest of the data is even good. I'm just going with Nexy's standpoint that "hard errors" need to be replaced with 0x55, so any protection sectors that are physically unreadable (Rings) or with a fixed amount of C2 error pointers, regardless of how many bits. If someone has a better idea, let us know.

Can you tell us how the descrambling works again? I mean, for mastering errors, what are the criteria to descramble?

1. Sector needs to be the data [Ctrl byte of subQ is 4 or 6]
2. Sync needs to be valid [00 FF FF FF FF FF FF FF FF FF FF 00]
3-1. If mode is 0x60, 2336 bytes need to be zero.
3-2. If mode is 0x61 and reserved area (from 0x814 to 0x81b) is reversed (all zero), it's descrambled.
3-3. If mode is reversed (0x00 or 0x01 or 0x02), it's descrambled.
3-4. If mode is unknown and msf is reversed and reserved area isn't all zero, it's not descrambled.
3-5. If mode is unknown and msf isn't reversed and reserved area is all zero, it's descrambled.
3-6. If mode is unknown and msf isn't reversed and reserved area is invalid, it's not descrambled.

Ok, so the VOB sectors remain scrambled. Did we cover everything then?

scrambled.

I guess we should use the same criteria for these sectors.

Did i read it right, sarami, are you fixing invalid sync/msf/mode?
It should not be a thing.

It was fixed before, for protection-related sectors that were replaced with 0x55. But we are stepping away from that now.

Is that scrambled or unscrambled?

It looks like it should be kept in that format

I guess the only reason for these manual fixes was to get a "proper" sync/msf/mode to fill it with 0x55?
So if these sectors are no longer replaced with 0x55, the code is obsolete and can be removed?

And are unreadable sectors (e.g. ring protection) replaced with 0x00, not 0x55?

They are still 0x55 when inside a data track (they normally have C2 errors)

OK. And I have another question.
The sector of VOB protection with "00 FF 00 FF 00 FF 00 FF  00 FF 00 FF 00 FF 00 FF" should be handled as data sector to be descrambled?

Do you have an example of output? Is the rest of the sector formatted as data?

Hello,

thanks for bringing that disc to our attention. It seems to be the Canadian release of the game.

I'm assuming that you have the original disc? Feel free to submit the dump info (and also the ringcodes) in this thread.

@sarami, after a discussion, we decided that only protection sectors with C2 errors should be replaced with 0x55 (and a proper sync/header with the same mode as the track).

So, SafeDisc dumps are unaffected, but some other protections (mainly SmartE, CD.IDX, VOB ProtectCD, 3PLock) will need to be rechecked/redumped. List of discs: https://pastebin.com/raw/77HPm5qx

Can you confirm if DIC already works this way? I guess EccEdc is only fixing the sectors that DIC is telling it to, so as long as /sf only flags C2 errored sectors of the above protections, it should be correct.

It doesn't look like JagCD discs have the standard values on those.

They have the same 11400 sectors area between sessions as all other discs so far. Even though DIC is reporting wrong values, e.g.:

REM SESSION 02
REM LEAD-IN 01:00:20
REM PREGAP 00:02:00

But it doesn't seem to affect the dump itself.. sarami and RevQuixo got the same dump for Vid Grid, but different session 2 lead-in and pregap.

So, I'm adding them with 01:00:00 and 00:02:00. There is no reason to suspect anything different.

It seems plex can't get sub-channel of pregap of 1st track of 2nd session exactly.

So, the dump may be correct, but the cuesheet is probably wrong?

Maybe just assume:
REM SESSION 02
REM LEAD-IN 01:00:00
REM PREGAP 00:02:00

?

Did you make any new research on this, Led?

first type seed is only 32bit, 256^4 combinations

second type seed is 128bit, 256^16 combinations, impossible to bruteforce, forever

So, the tool is useless for most discs.

@iR0b0t, maybe you can add type = Single-Density Area + High-Density Area to the disc page of Dreamcast discs? the same way as is done with Multisession discs.

ps. I've updated (hopefully) all the existing Multisession discs to have the correct cuesheets and comments: http://redump.org/discs/quicksearch/ses … ents/only/
