if you open them with an hex editor (or simply listen them) there is 2 sec (or 1.74) of silence at the end of every track, so probably E and U SCD games were wrongly mastered in many ways.

lol, same for the hundreds of pc/psx/cd32/etc. CDs - there is a silence, but no gap specified in the TOC.

I think the same.

Moreover many Euro SCD games have no gaps from track 3 to last, by the way if you open them with an hex editor (or simply listen them) there is 2 sec (or 1.74) of silence at the end of every track, so probably E and U SCD games were wrongly mastered in many ways.

Those are the gaps returned by EAC and PerfectRip, in Tosec they're like that too. They're just about as wrong as the tracks we're discussing in this thread, in other words they're surely wrong, but only because they come from bad mastering, all of them should be 2.00.

That it's the point, we are seeing that the tracks are bad mastered, what do we do, correct it or just leave it alone?

Japan audio tracks are ok, but USA ones have data at the beginning of every track (03-35). The ammount of data is near 1sector/2352bytes that is the difference in pregap -> USA 2.00 - JAPAN 1.74. Probably also the difference of the 2 offsets (+1971).
Japan tracks end with only some bytes of silence 0x00 so this difference in pregap-offset moves data to next track.
Listening to USA audio tracks you don't hear any distorsion at the start.

If offset+pregap of USA version are right, there's nothing to do, they were mastered this way.

The subchannel check I did was on a .sub file extracted with clonecd. The "actual" (specified in the subchannel data) gap is 2.02. However the audio data suggests the gap should be 2.00. The question is wether to correct a mastering error or keep the data formatted the same as on the original media.

I think huygens is right, that this is a matter of what the project is trying to pursue, authenticity according the original media, or info based on what the data should be according to mastering standards.
I feel like the spirit of the project is the original media thing, but also feel a little bit uncomfortable about dumps that doesn't seem to be right, just my two cents. smile

What the administrators think about it?

The subchannel check I did was on a .sub file extracted with clonecd. The "actual" (specified in the subchannel data) gap is 2.02. However the audio data suggests the gap should be 2.00. The question is wether to correct a mastering error or keep the data formatted the same as on the original media. It seems more in keeping with the project to keep the format consistant with the original media.


I was wondering about Final Fight myself.

I think the 2.02 pregap is right, imho.

I think that is because they must use EAC to dump the audio, too.

Those gaps are totally weird... big_smile:D

There's a lot of dump that has this same problem. Huygens, have you tried to dump the disc with PerfectRip???

I think the 2.02 pregap is right, imho.

Even if the first 2 sectors seem like the last 2 sectors of next tracks, I think, EAC value is ok.

I didn't notice that. I did check the subcode and it indicates 2.02. However it seems to me the main channel data should take precedence.
Here the hash info for tracks 9-11 with 2.00 gaps. I think a mention of the bad gap data should go in the notes section for anyone dumping the disc in future.
