hello, gigadeath! i hope to get some of games you listed somewhere next week.

That's great, it would be good to have other dumps to compare!

In the meantime I tried dumped with PerfectRip with no success. PerfectRip gives me various errors on both drives, things like "injected sub between track 1 and 2", and I can't complete the dumping process with either drive. The drives (one is LG and one is Philips) are not old and in good condition, I never had a problem with EAC, so I'll stick with the IsoBuster/EAC combo.

The discs are uber-mint so the problem is that PerfectRip doesn't go along well with my drives.

hi!
and sorry for long delay.

i just got Tenkafubu/Jikocyushunha2/Sangokishi III from your list and Winning Post couple of hours ago
and so far i only had time to look at Tenkafubu
eac gives gap 2 for 1st audio and 1.74 for the rest
but strange thing is, on every drive, isobuster gives different absolute offset!?
1803/627/1799
i would think it's my mistake to do calc in hurry but this difference is visible even when reading 1st audio by relative ones.
tho it's possible to get crcs to mach if one offset is taken as default and the others adjusted by data difference in dumped tracks.
if for example 1st audio track's, 1st data byte is 5e08e, crc32 : 7a802c1a

sorry it's not much and this is all for now
...didn't had that much time, but i'll try to spend more on this in the next few days

Do you mean the amount of descrambled data (garbage)? It should be different on every drive, this is the value you should use in EAC. To get disc write offset, simply subtract drive offset value from the amount of descrambled data.

no, no after that. after i substract.
but i've found out it's my mistake. i went to check one sector back from first pregap to see if it's data track (wasn't sure about 2sec)
and if i do that, turns out isobuster does not get offset correct afterwards.
it's 1803 after all.
i'll post crcs tomorrow.

Please see the comments I posted on Tenkafubu dump

I have a question.

Some Mega CD discs have a 2 tracks layout (1 large data track + 1 very small audio track).

For these discs EAC reports a 0.00 pregap for track 2, CDRwin reports a 2.00 pregap.

If EAC is right, I shouldn't remove any pregap from the data track, since track 2 pregap is 0, should I?

This could be a bug in EAC.. You can try right click Track02 > Sector View in IsoBuster, then going back 152 sectors and then forward again until the sync (00 FF FF FF FF FF FF FF etc) is no longer visible.. then you will know where the data track ends and what the pregap length really is.

By the way, all that who copies the Japanese disks for SS and MCD I urgently would recommend to check correctness of last audio  track as at offset equal 1000 + the probability of loss data in last sectors of last audiotrack is great.
For an example. From 20 disks for SS which I have copied, only at pair last audiotrack on a drive with offset +6 (EAC) was correctly copied.
I should use other drive with offest equal -1164 to extinguish huge positive offset the Japanese disks.
Forgive my English
