Dumping CDLock CD's

[Haldrie]

Tomb Raider III is listed as having Illegal TOC on some copy protection web sites (don't remember which ones as I saw this a long time ago). My guess is the reason why it was considered Illegal was because disc copying software at the time this copy protection was released was unable to handle ripping the second data track. These days disc copy software gets around this issue by raw ripping the disc even when it's only ripping a single track at a time.

[EDIT]
Also bin/cue does support this as I've run my own image of Tomb Raider III from the bin/cue dump I've made of it. It might not have with virtual drives back then but now it's no problem for them.

well it goes

DATA TRACK
AUDIO TRACK
AUDIO TRACK
DATA TRACK

bin/cue doesn't support this, just like CD Extra.

CD Extra is multisession, that's why the BIN/CUE format can't be used with it. In this case we are dealing with only one session with multiple data tracks inside, and that's fully supported by the CUE format.

Okidoki, shouldn't be a problem then.

A question about cdlock, where is the pregap of the data track (track 4) goes? to the begining of it?

[iR0b0t]

yes ghosty, (pre) means before 

[ghost]

Yes but what I mean is that you have to manualy add a bunch of 00s in the beginning of the data track?

[iR0b0t]

Depends on whats recorded in the subs, so it would be better to examine them.

When you know the exact pregap length you can go back in isobuster and when there are data sectors you have to extract them first and add to the track.

Also, it could happen that there is a mixed pregap of audio and data sectors.

Will have to make a little guide for this. I think there is a workable system for doing it, I have to thank fireball and ir0b0t for checking the subs and helping me out with it.

I'll try to put together an addendum for the dumping guide, just for this protection. Problem is I don't know how to analyze subs properly yet. If there was a good tool for it released soon it would help.

A combination of ISOBuster, EAC, cdtoimg, descramble_CDDA, a calculator and a hex editor is needed to do it.
