I have at least 3 games with bonus audio CD, are they needed and how I have to dump them?

For example, this is the cue for Burning Rangers bonus audio CD:

FILE "Track01.wav" WAVE
  TRACK 01 AUDIO
    INDEX 00 00:00:00
    INDEX 01 00:00:37
FILE "Track02.wav" WAVE
  TRACK 02 AUDIO
    INDEX 00 00:00:00
    INDEX 01 00:01:74
FILE "Track03.wav" WAVE
  TRACK 03 AUDIO
    INDEX 00 00:00:00
    INDEX 01 00:01:74

Pregap of first track is 2.00+0.37. How can I find offset, if there's one?
And file format: pcm as games or wav?

Here is a try dumping with perfect rip with write offset = 0 and pcm format.

My patch requests thread
--------------------------------

would be great, i'd be happy to add them too. they're seldom and perhaps obscure.
tho it's impossible to determine offset directly without data track maybe sometimes there would be similarities to game cd or data would exceed gaps for certain amount of samples.
but we could indeed dump most cds compensating drive offset, like you did.
and for cds that would not fit into this frame we could dump from first meaningful sample or until the last one (shifting frame to cover all data).
and 'offset' field would represent any changes: 0 - drive offset cancellation; -x,+x - shift, so people could verify these cds just like everything else.

I'll post in a separate thread or in this one the other Bonus Audio CD while I find/dump them, then if someone want to add them...

ok
it's up to Dremora though

Well, although some may disagree, I thinkk that each bonus Audio CD is part of the game and should be dumped too.

There is no way to detect an offset if disc has no data tracks, so they should with 0 write offset.

PCM.

Thanks for answer, Dremora! And for big news!

I'll add within minutes some bonus audio CD to the wip!

thank you very much!

OST CDs for previous dumps should also be dumped, then. Like this one - http://forum.redump.org/viewtopic.php?id=2114
