DreamMovie in BIN/CUE format for preservation purposes.

Also, fresh CDI made with Discjuggler 6.

BIN/CUE is NOT selfboot burnable or mountable, but runs under demul and can be viewed/extracted by Isobuster.

CDI is fully supported.

Since when? REDUMP format is BIN/CUE. Some ODE's support BIN/CUE. Try it, it runs under demul. I made it from the CD, not the image, using Imgburn. Isobuster shows 2 sessions. :?:

Redump uses CUE/BIN to store and describe GD-ROMs, not CD-ROMs in multi-session MIL-CD format. DreamMovie was not a GD-ROM. GD-ROMs aren't multi-session, but instead contain three separate areas with three separate TOCs (commonly termed single-density area, logo area, and high-density area).

EDIT: Looking at your CUE...

Code: Select all

FILE "DCVCD5.BIN" BINARY
REM SESSION 01
    TRACK 01 AUDIO
      INDEX 01 00:00:00
  REM LEAD-OUT 01:45:11
REM SESSION 02
    TRACK 02 MODE2/2352
      INDEX 01 04:17:11


...I do see the two sessions, but I don't know enough about sessions in CUE sheets to say whether or not burning your CUE/BIN pair would actually result in a bootable disc on hardware.

REDUMP = no MIL-CD

Right, the burning part I never tested, I was wondering about that myself.
My post did say for preservation purposes.

Hey, derek, what up?

REM SESSION 01
REM - remark

The main part of the programs when processing the CUE file seeing the REM string misses it.
Yes, in some programs, supported by an extended set was added, but it would rather exception than the rule
You can try to mount your image in Daemon Tools and you will see that your image is not working.
Redump is the worst sample to follow, their images are just terrible

Called block 1 and 2 and block 3

Code: Select all

GD-ROM structureThe disc is structurally divided into three blocks.The innermost area is called the compact area, where data and CDDA are stored in a format that conforms to the general CD-ROM standard.Can be done.Of course, you can browse this area on your CD player or computer.This area is only about 4 minutes, so for example"This disc is a game disc for Sega Dreamcast. It does not play because it contains game data.Please. "It is expected that you will put in a message like that used in SATURN.Also, you cannot access this area from the Dreamcast software.The next area is a dense area,You can store game data, programs, CD-DA data (used in the game), etc. here.Congested area High density areaFigure
