Disc dumped, -647 offset confirmed

I understood that. i was just assuming that at least one of the dumpers had the other offset and it was missing from the DB

Well, for now i can't dump that disc (that disc and many others... )

Well when someone dumps the game with -647 it would be added. I don't know off hand but I dumped a game with a different write offset then the one posted and it has both write offsets in the db. We can't take your disc that isn't dumped and add -647 to it because your disc audio might be different, for example my two dumps of Shining Force CD, both discs had the same offset +222 but the audio was different with the data track the same.

As for the other, it could be reversed, someone else will have to explain this one further.

Thks for the explanation, pepsidrinker.
well it seems that, for me, the write offset sometimes is a problem
i mean the info in the feft column lol but why one dump is 1.0 and the other 1.1? it also could be the other way around...
and i think that the two write offsets should be in the info...

Because the game was pressed with two different offsets. That's the beauty of our method, write offset isn't a problem. As for the other question the data track is different and so we make one 1.0 and the other 1.1.

I don't know if this should be posted in the "Fixes and additions" so sorry if it's misplaced.
I tried to make a verification dump of ISS PRO and my drive couldn't dump the audio tracks because it has a read offset of +48 and this always happens to me in PSX discs whith a -647 write offset the problem is that the dump in the DB is a +2 offset.
I dumped the data track and after fixing, it matched this dump http://redump.org/disc/1755/
So what's wrong in this picture? 3 dumpers can't be wrong... so the info in the DB is wrong (not the dump) or my disc is different...
And anyone knows why this dump http://redump.org/disc/5470/ is v1.1? i mean the info is the same in both dumps (even the EXE date)
