Hi,

Some times ago, I submitted a "game/music" software named "eJay Rave 2".
I know that this kind of software is not in the scope of Redump, but I would like to keep a functionnal personnal backup of this disc.

(Discarded dump link : http://forum.redump.org/topic/57900/rave-2-ejay/)

I've noticed that sometimes, when a game is added to the Redump Library, the "cue" file is different from the on generated by MPF, the "MODE" in particular.

Here is the one generated for "eJay Rave 2" :

FILE "RAVE_EJAY2.bin" BINARY
  TRACK 01 MODE1/2352
    INDEX 01 00:00:00

So, here is my question : Does the "cue" file content seems correct to you ? (Particularly the "MODE" ?)

If someone would be kind enough to help me, here are the logs : https://mega.nz/file/pa41TbgJ#OyTf8LLsE … DVt9RKp4lM

Data sectors, as opposed to audio sectors, are all structured this way: sync, addr, mode, +/-subh, data, +/-edc, +/-null, +/-ecc.
The mode consists of one single byte located at the 16th position of every sector and can easily be checked with an hex editor.

Some examples:
- a mode 0 sector
00 FF FF FF FF FF FF FF FF FF FF 00 25 59 34 00
- a mode 1 sector
00 FF FF FF FF FF FF FF FF FF FF 00 10 38 72 01
- a mode 2 sector
00 FF FF FF FF FF FF FF FF FF FF 00 54 17 36 02

If you are a Windows user, I would suggest to use HxD to open your disc image.

Otherwise, edccchk automatically analyzes and prints a report that specifies the sectors mode.

Thanks !

I was able to check my backup using edccchk.

(I'll use edccchk as it's more convenient)
