Xenogears, try to redump game with perfectrip (if you get again bad results, try at a lower speed or dump track by track adding pregap created to next track). I got same results even working with isobuster and moving pregap, remember pregap of track03 if dumped with EAC. As I said above it could be a different dump or it could match Themabus/mine. Ring code was the same, so at 99% you'll get the same dump.

I am sure my dump is correct, but I will redump them again

PX-760A (+30), PX-W4824TA (+98), GSA-H42L (+667), GDR-8164B (+102), SH-D162D (+6), SOHD-167T (+12)

It was already discussed, mine was dumped too a lot of times with same result (both EAC 2 drives & PR).
There are 4 cover versions o VF Remix http://www.satakore.com/sega-saturn-gam … x-JPN.html and so probably there are different mastering, I asked to check which version are the dumps in DB.

1 - Spin card blue writing & "special limited edition" sticker
2 - Spin card red writing & "special limited edition" sticker
3 - No spin card
4 - No spin card & "special limited edition" red box on instructions

Mine is 2.

I understand "different mastering" when it comes to audiotracks, but not about the data (of course, if the datatrack itself is the same within those 4 versions).

I think they may have resized data track in different masterings (it could be even a mastering error). Anyway, px_d8 finds 0 as write offset.

here is the topics discussed in the past:
http://forum.redump.org/viewtopic.php?pid=7519#p7519
http://forum.redump.org/viewtopic.php?id=3349

In second discussion I haven't read that Themabus suggested quite same things I did above for Xenogears Slayers Royal dumps.

Just so you know, it's possible that px_d8 indicates a +0 write offset on the data track and that the other method gives you a different value! I've had this with several ibm pc discs, and it lead me to conclude that the data track can sometimes be mastered WITHOUT ANY WRITE OFFSET.. If you get +0 using px_d8, it's best to try the other method as well because it might give a different value on the audio tracks!..

ps. because some discs showed no write offset on the data track and a different value on the audio tracks using the other method, this proved for us that the EAC reference offset is correct. Some people argued before that the EAC reference is off by 30 samples (and that most Plextor drives have a +0 read offset)..However, that must be wrong, because a disc can't have 2 different write offsets and a Plextor drive gives +30 using px_d8 on these discs, so that +30 must be the read offset part (the write offset part isn't shown in px_d8 on these discs).

Vigi, but even EAC reports pregap 1.74 for track02 so there's no doubt about offset. Here is LBA sector 5754 of my disc and you can see offset is +0.
Moreover, also with this disc IB gets frozen if I go one more sector back (5753 if pregap was 2.00) so I will dump sub to check (CD tools cannot dump it like Cyberbots because an error stops dumps quite around end of data track ---> mastering error?) with Alcohol and post it.

LBA :5754

Not a mastering error, 5753 is a data sector, but the audio was shifted by 588 samples and this sector is full of garbage now, your drive tries to descramble it and locks up, because there is no synchro (due to the +588 writing offset).

I will check everything in the next hours.

If you have Plextor, you can also try this tool, it's modified version of px_d8 and should automatically calculate an offset. Unfortunately I was not able to test it because I don't have drive with D8 command support, but my code at least was working with the images Please report any bugs.

Thanks Dremora, great mod.

log

Sector: 5753
MSF: 01:18:53
Combined offset: +120 bytes / +30 samples

and setting to 5752 (if track was smaller as other dumps)

Sector: 5752
MSF: 01:18:52
Combined offset: +120 bytes / +30 samples

at 5754, beginning of pregap it returns

Error searching for sync!

offset is always 0. By the way the sub from alcohol seems to set pregap (and so data track size) to other dumps, 2.00.
Complete Sub
It could be that a sector is moved, but offset is always = +0
In my opinion everything is right.

I redumped at 4x first 3 tracks with PR, and it reports the common error in pregap (similar to many discs). I have 2 other old logs of PR (one has the same error and another one has many more alway in pregap, but final dumps were the same).

Dremora, please let me know what do you think about SS games with no pregap detection on PR, I uploaded a pair of sub here http://forum.redump.org/viewtopic.php?id=3152

I added a note because I noticed that same disc with different ring code (at least I hope it's only that) may change this strange structure. I found it converting Tosec Fighting Vipers (J) (GS-9101P-01012A-P1C V) (even GS-9101P-01012A-P3C V) to iR0b0t dump (GS-9101P-01012A-P2C V). Both tosec dump have one track with pregap of 2.00 (now there's also a track with 1.00 but it was not like this in the dump I had), but iR0bot's one has the regular 1.74 ***

*** iR0b0t can you confirm that pregap of your dump is what was found by PR?

It will be wird to have two alternatives dumps, for example, differing only of one sector moved between 2 tracks, but if that it's the real thing it has to be like this (if some discs were mastered with M2 sectors in these pregaps, and others not, they are two differnt versions).

Again about Virtua Fighter Remix dumps.

p_star: GS-9039P-00348 3MB7 C 56
asapy: GS-9039P-00348 4M7 C 56

mine: GS-9039P-00348 6M3 C 56
iR0b0t: GS-9039P-00348 5MB3 C 56

This may exist too:
GS-9039P-003448 2MB3 C 56
GS-9039P-00348 4M3 C 56

Seems two different revisions of two different mastering according to ring code. As we can have even 20 alternatives of this game, it should be better to identify also the different cover, if this difference determines ring codes.
For example:

Virtua Fighter Remix (J) (Red Spin)
Virtua Fighter Remix (J) (Blue Spin)
Virtua Fighter Remix (J) (No Spin)
Virtua Fighter Remix (J) (Special Cover)

PS: iR0b0t are you sure your copy is the one without spin card? Was it sealed like this?

do you mean my "Fighting Vipers" dump now?
I am also always dumping discs on two ways (EAC & PR) and compare then hashes and gaps/pregaps for correction. I will redump "Fighting Vipers" and post PR log ones again.

I am not, because it wasn't sealed, but my copy has no Special Covers & no red or blue scripted Stickers !

Ok, I need only confermation. So if tomorrow someone dumps another copy of Fighting Vipers (J) and it returns one or more tracks with pregap of 2.00 (EAC, on PR you'll have 0 pregap), it has to be considered alternate (unless meanwhile something new will be discovered) if subcode has an M2 sector at the end of pregap.

Sticker is on the seal and red/blue writing is on the spin card. So yours could be 1, 2 or 3 if you have no spin.

Disc 2 is also an alt version, Data track matches yours, but track 2 is matching my disc 1 - so you can simply reproduce it

PX-760A (+30), PX-W4824TA (+98), GSA-H42L (+667), GDR-8164B (+102), SH-D162D (+6), SOHD-167T (+12)

What about these dupes?:

http://redump.org/disc/3677/
http://redump.org/disc/1456/
http://redump.org/disc/3681/

Has anyone analyzed the audio differences?

All these dupes with same data track and different audio track are pretty useless imho.. maybe it would be good to use parent/clone in the .dat to avoid having the same data track in 5 different zips. Or maybe the dumping process just isn't optimal / offset isn't analyzed correctly.

I really hoped that our method of offset correction would prevent any dupes for saturn the way it does for psx (games with different audio offset but same checksums.. Doom (E) for instance), but so far it doesn't seem to help at all.

About Sakura Taisen, at least Alt has the same tracks now, and it shoul be the same of below.

About those Vampire Hunter tracks.

Alt1 and Alt2 differ of 1 sample.
Yes, fuzzball dump misses pregap in cue, it has to be fixed.

This difference of ~1-4 samples is the same for other 2 tracks alts in DB.

This is why an 'intelligent checksum' (a checksum which is calculated over the non-zero data bytes) like Eidolon proposed really isn't a bad idea for Saturn.. It would allow us to ignore the offset (though the values should of course still be stored in the db) and get rid of these useless dupes. After all, our method of offset correction is useless for this system.

The only problem then is that there can be infinitely 'correct' dumps of a file, as long as the size and the checksum of the non-zero bytes matches.. how would we determine which offset alternative and which (normal) checksums should be included in the .dat for each track?

If Sega made a different mastering with different offset I think it has to be archived as it was, otherwise there's no perfect rip at all. The problem of this alternatives could be solved simply adding only alt audio tracks and alt cues (a thing similar to mame sets), but DB system has to be changed this way.

ex. of Vampire Hunter - Darkstalkers' Revenge (J) (Alt 1) cue like I say

FILE "Vampire Hunter - Darkstalkers' Revenge (J) (Track 1).bin" BINARY
  TRACK 01 MODE1/2352
    INDEX 01 00:00:00
FILE "Vampire Hunter - Darkstalkers' Revenge (J) (Track 2) (Alt 1).bin" BINARY
  TRACK 02 AUDIO

If I understand well, anyway the primary dump should be the one with more positive offset correction in mastering to avoid missing data*** at the end of track. The 3 VH are arranged this way 0 -4 -5.

***How can be calculated a checksum over non-zero data if some bytes are missing?
