Re: [DONE] Discussing the multisession cue

Post by MrPepka »

I have the impression that this line does not always work with every disc. I checked the CD Maniak Wydanie Specjalne 2/2008 and there, adding a PREGAP line to the cue file does nothing, IsoBuster still doesn't detect files on this CD (except for the fairy tale on the audio track). The fairy tale itself does not play from this disc either (the disc image is damaged?). I checked a CD from Gazeta Wyborcza (the one with the Speedway Championship game, for example) and the PREGAP line worked there, but when unpacking files from IsoBuster to a folder, messages about bad sectors started appearing. The CD called "FrogMan + Tajemnicza Wyspa" also does not work (same results as with "CD Maniak Wydanie Specjalne")

There are no problems here:

Code: Select all

REM SESSION 01
FILE "CD Maniak Wydanie Specjalne 2-2008 (Poland) (Track 1).bin" BINARY
  TRACK 01 AUDIO
    INDEX 01 00:00:00
REM SESSION 02
FILE "CD Maniak Wydanie Specjalne 2-2008 (Poland) (Track 2).bin" BINARY
  TRACK 02 MODE2/2352
    PREGAP 02:32:00
    INDEX 01 00:00:00

You'll have to be more specific and provide a link to the disc.

The dumps themselves should all be fine and there's no sign of any corruption.

OK, I checked CD Maniak Wydanie Specjalne 2/2008 again and it turns out that I messed up because I had the track order changed in the bin file names. Now the disc image works for me and I can see that the CD is the same (its content) as on the Max Kids Dziewczynka 1/2006 CD. On the other hand, when it comes to the CD "FrogMan + Tajemnicza Wyspa", I also changed the order of the tracks to the correct order in the names of bin files and then the PREGAP line worked, but after opening a cue file in IsoBuster an attempt to open a data track results in errors, and after skipping them all this track is unreadable

Oh, for the sake of clarity, those malfunctioning drives are the ones below:

Jackal wrote:Someone pointed out in Discord that the multisession cuesheets for IBM PC aren't functional. It's true that virtual drive software like Daemon Tools doesn't support multisession cue's, but IsoBuster also fails to parse the filesystem correctly when loading the .cue.

The problem is that IsoBuster assumes that SESSION 02 starts the sector after SESSION 01 ends, but in fact there's 11400 sectors in between the sessions that aren't included in the image.

So to fill this void we would need to add this line to the cuesheet: PREGAP 02:32:00

Mounts with Daemon Tools without error (but no multisession). Opens in IsoBuster and parses filesystem correctly:

Code: Select all

REM SESSION 01
FILE "Bajki na CD 5-2008 (Poland) (Track 1).bin" BINARY
  TRACK 01 AUDIO
    INDEX 01 00:00:00
REM SESSION 02
FILE "Bajki na CD 5-2008 (Poland) (Track 2).bin" BINARY
  TRACK 02 MODE2/2352
    PREGAP 02:32:00
    INDEX 01 00:00:00
Default redump .cue: Mounts with Daemon tools and opens with IsoBuster, but the disc size is 11400 sectors too short and IsoBuster is unable to show the correct filesystem for session 2, because it's missing the area between the 2 sessions:

Code: Select all

REM SESSION 01
FILE "Bajki na CD 5-2008 (Poland) (Track 1).bin" BINARY
  TRACK 01 AUDIO
    INDEX 01 00:00:00
REM SESSION 02
FILE "Bajki na CD 5-2008 (Poland) (Track 2).bin" BINARY
  TRACK 02 MODE2/2352
    INDEX 01 00:00:00
IMO iR0b0t should add the PREGAP 02:32:00 line for generated multisession CD cuesheets, so that we at least can access the session 2 filesystem with the correct start address and have the correct disc length.
Hi, I have some multisession CDs that have data track in session 2, I can mount cuesheets with Alcohol but not the ccd file, and I can't get access to session 2, also IsoBuster fails to identify them as multisession CDs. I tried your method with no luck, am I doing it wrong? Here are some of un-modified cuesheets

You need to download the cuesheets from redump. The ones that are generated by the dumping tool aren't compatible. And then add the PREGAP 02:32:00 line like above.

The second track from the FrogMan CD actually works in IsoBuster?
And as for the album Gazeta uczy i bawi, you unpacked the files from the 6th track without any problems?

OK, it was my mistake with this CD with FrogMan, because I did not have the PREGAP line added, after adding it to the right place in the cue file, the CD worked, but its content is the same as on the CD Kraina Zabawek 1/2008. However, I checked my cue file from the disc Gazeta uczy i bawi and it is the same as yours, IsoBuster sees the data track, but an attempt to unpack the files causes messages about bad sectors to appear at some point
