Sega CD 32X questions

Actually PerfectRip's track02 you uploaded has less than 2 second of pregap, and EAC's has exactly 352800 bytes of pregap (which are the ones you added), so it's probable that EAC cut some data at the beginning. I prefer to hear what Vigi/Dremora/Themabus have to say. A -924 offset is exceptional, maybe there's an issue with that.

[gigadeath]

Yes, EAC's track02 definitely miss data at the beginning, data that's present in PerfectRip's, which in turn has definitely less than 2 seconds of pregap silence

It could be wrong offset messing things up or gap being different than 2 secs. Can you post PerfectRip cue?

[pepsidrinker]

Ok, why would it be less than 2 second of pregap? The cue says 2 seconds.

The first two tracks you've uploaded have difference only in pregap, the tracks dumped with -924 are completely different. Are you sure you've dumped them with the same offset?

[pepsidrinker]

No, sorry it was -954 with EAC...

I just dumped track 2 with pr with out dumping track 1 with it and it gave the same md5 as EAC with offset -924.

Could all the sub-channel errors that perfectrip gets effect the gap and make it messed up?

Gigadeath...

When you said if the perfectrip track 01 matches the one with ISOBuster and I said yes. It does match but I resized the ISO buster image of a 2 second gap and I didn't touch the Perfectrip track 01....  It seems to me somewhere Perfectrip is screwing up the gap?


here is the -924 EAC and PR track 02..

[gigadeath]

AFAIK PerfectRip should give right size track01 without resizing. If PerfectRip's untouched and IsoBuster's resized match, then it's right.

Track02 still has issues, I see that PerfectRip file still has less than 2.00 pregap, and EAC file still misses data at the beginning.

Can you look at actual disc lenght in sectors with IsoBuster?

[pepsidrinker]

I will do that. But I messed up and I am going to see if that is the problem. I am redumping them now.  I never took out the - in Perfectrip so that it was a positive.

In EAC I have it set to positive, which is correct right? Or do you put it as -924?

[gigadeath]

-924 in EAC and +924 in PerfectRip.

EAC -> exact combined offset
PerfectRip -> inverted sign

[pepsidrinker]

Thanks.. but even with that fixed it's still not matching.

266474 is the amount of sectors ISOBuster gives for the cd...

Daemon doesn't let me load the cue from perfectrip.

I had to fix the cue perfectrip made... It matches the cd.

ISOBuster and EAC + added gap matches the cd also.

[gigadeath]

Are you always detecting gaps before dumpigng with EAC? Even if it returns 0.00 it's necessary to hit F4 before dumping. Even without manually adding pregap, EAC resulting file shouldn't begin directly with data.
