CFC.DIG extraction script

[Taylor17387]

I'm trying to unpack a CFC.DIG file using this script:

Code: Select all

# CFC.DIG
# script for QuickBMS http://quickbms.aluigi.org

get INFO_LIMIT asize
for i = 0
    savepos TMP
    if TMP u>= INFO_LIMIT
        break
    endif

    get OFFSET long
    get SIZE long
    get CHANS short
    get TYPE short
    get FREQ long
    math OFFSET * 0x800

    if SIZE != 0
        if i == 0
            math INFO_LIMIT = OFFSET
        endif

        string NAME p "%d/%08x_%d_%d.raw" TYPE i FREQ CHANS
        log NAME OFFSET SIZE
        math i + 1
    endif
next

However, I'm not sure if it's a generic script for all .DIG files or if it was written for a specific game. Upon extraction I get a folder with audio files in .raw and the IECS header (I believe this folder is right, but it's just 42 MB of the 352 MB of the whole file). But then the second folder has lots of unidentified .raw files without header. This game stores all data inside this CFC.DIG, except cutscenes and voiceover audio which are in separate files. So I expected to extract files for textures, 3D models and dialogue, and not just audio.
I don't know if the script was simply written for a different game or if those .raw files are really the only thing that can be extracted.

This is the file I'm trying to extract:

It's from the PS2 game Kami o Tsugu Shoujo (SLPM_660.73). The first game of this series also stored all data in a .DIG file, only that it was called CDDATA.DIG.

That script works perfectly.
It was created to extract the audio data from a Naruto game in this topic: viewtopic.php?t=2675
Take a look there if you can find more info but that's just audio data and nothing else.

Then it's only audio? But there are no more files inside the .iso, only the movies, voice audio, SLPM_660.73 .elf file, and .IRX modules. By elimination, everything else should be inside the .DIG file.
Now I know that some Square-Enix games have hidden files that can't be extracted from iso. For example, Final Fantasy X is around 4 GB, while the extracted contents are just 5 MB, but I doubt this is the case here. Opening the .iso in a hex editor doesn't reveal any more files, and the extracted contents are 2 GB, which is the size of the original iso.
Could the textures, etc. be inside SLPM_660.73? Is that even possible?

[aluigi]

There are two folders extracted:
0: contains the ICESsreV files (search on Google)
1: I don't know what files are them, they start with 00 05

What I can say for sure is that the extraction is complete so what you have there is the whole content of cfc.dig

Ok, thanks. I suppose those .raw files are then the textures and everything else. Too bad they don't seem decipherable.

[aluigi]

The files in the folder 1 are 100% compressed (imho), the decompressed size is the FREQ field while I don't know what's the meaning of the CHANS one (1, 4, 32 and so on... maybe chunks?).
Anyway I don't know what's the compression algorithm so nothing to do with these files.

[Taylor17387]

I see. Well at least that's knowing something... At first I thought the CHANS numbers referred to the type of file.
Could I use the "QuickBMS comtype scanner 2" on these .raw files?

[aluigi]

I already did it.

Then I guess I've reached a dead end
Thanks anyway for all the help.
