Thank you iRobot, here's my updated cue dumped with /ms:

How long before we can add Mil-CD? Thanks!

Added.
There are still some open questions though:

All the discs so far, including Bleemcast, have the same lead-out, lead-in, pregap lengths between sessions. They are formally specified in official documents, so it's unlikely that a disc will deviate from it.
I just took a look at all the MIL-CD logs and they all have non-standard values.
Lets see if this remains after they have been redumped with the latest DIC version, since there was a bug apparently.

iRobot, can you add CD format for Dreamcast so unlicensed discs can be submitted?

"unlicensed discs" are apparently all MIL-CD

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.
