Ys Book I & II ( http://redump.org/disc/32091/ ) states that "The first 2 sectors of the 3rd track's pregap are scrambled data sectors."

This is actually wrong, it should be the first 3 sectors, not 2.  I was fixing a clone CD version of this from the Trurip set to match the new database entry here at Redump when I discovered this.  The trurip image was perfect except the checksums for track 3 wouldn't match until I scrambled the first 3 sectors of it instead of just the first 2.  I managed to figure this out comparing the USA version to the Japanese version with a hex editor, the japanese track 3 is correct but is also 1 sector smaller in the pregap than the USA version.  I thought I should bring this to your attention so no one else pulls their hair out trying to get that track right.

So there's 3 scrambled sectors, then zeroes, and then the actual non-zero data starts at offset 376240 (5BDB0).

Maybe one day you assholes will actually get your shit together and create a goddamned SECURE WEBSITE using HTTPS?  Or better yet, get rid of this dumb split disc image format and provide dats with whole disc images and proper subchannel data.

It was also already obvious from the 00:02:03 pregap that it should be 3 sectors.. Fixed  smile

Yep, sorry, 7056 bytes :-P
