[DONE] Discussing the multisession cue

[user7]

Where are we at with this guys? Redump going offline kind of stuttered this conversation.

[Jackal]

I'd like to know if the TOC/subchannels of multisession discs (and/or rainbow books) really have a "RUN-OUT", "LEAD-OUT" and "LEAD-IN" marked between sessions. If they do, then I wonder why IsoBuster omitted the LEAD-IN.

[F1ReB4LL]

Can somebody dump any multisessional disc either with cdtoimg_d8 (if it even supports multisessional dumps?) or with swapping + isobuster? And the subchannels separately, since the additional TOC, if it's there, is stored in them.

Leadout sectors are surely there. I think, it is possible the 2nd session starts straight with the pregap sectors of the 1st track without any additional lead-in UNLESS it's a multisessional CD-R. Isobuster ignores the pregaps, so its cues aren't clear enough. Anyway, DIC needs to show not only where the leadout begins, but also where it ends (or its length), otherwise, since the tracks aren't merged into a single image, the address of the 2nd session is unclear.

DIC needs to show not only where the leadout begins, but also where it ends (or its length)

Uploaded test version
- added: Lead-out length of 1st session in _disc.txt (needs /ms flag)
- fixed: incorrect 'REM SESSION' position.

"RUN-OUT"

It seems old isobuster supports it. https://forum.daemon-tools.cc/showthread.php?t=6281
But latest version doesn't output it.

Tried doing a test. Super slow around Creating .scm (LBA) 118540/299510 of my dump. Had to cancel. It is a Audio tracks then data track at end.

[user7]

I left a Multisession game dumping overnight and its still going... is it supposed to take so long? It started going slow about 8000 sectors in. maybe I hit the second lead in?

[Jackal]

Tbh any dump that goes 1 sector per second can't be good

[user7]

In that case, canceled. Here's the logs: https://drive.google.com/file/d/15_cD3W … sp=sharing

sarami, maybe you need a multisession disc to test? One of the Japanese unlicensed Action Replay Dreamcast discs come to mind.

Can PX-708A get the TOC?

Code: Select all

DiscImageCreator audio <DriveLetter> TOC 4 -5000 -1100

or get the index 0 of track 1?

Code: Select all

DiscImageCreator cd <DriveLetter> <Filename> <DriveSpeed(0-72)> /p

If not, dic can't support /ms flag for PX-708A.

[user7]

I tested with a 708 and 755 the disc from my first test:
