"Demon Hunter Legion" is supposedly made with unreal engine (version 12791).
The game's contents, however, are stored in a series of .DAT files and I can not find a BMS script to unpack the .DAT.

I'm upping this as i think the gamefile have been update with a new version, after using the script, the file isn't recognized as unreal package at all.

I don't think I can do much here.
The script correctly extracts the data referenced there which is just one big non-compressed file (basically the original package0.dat archive without the header), and that's correct.

Inside the extracted 00000000.unr file there is just a sequence of various files, it's enough to search for c1 83 2a 9e to find all the Unreal files, but they have no references, are just concatenated there.

I checked trunk.dir and there are no references there too about these raw archived files in 00000000.unr.

Ah right, in short it means that there is no solution to dump the files from 00000000.unr

Try the following script, if you have do NOT have quickbms 0.7.5 then remove the -1 from the second findloc instruction:

Code:

findloc OFFSET binary "\xc1\x83\x2a\x9e"
do
    goto OFFSET
    get DUMMY long
    findloc NEXT_OFFSET binary "\xc1\x83\x2a\x9e" 0 "" -1
    if NEXT_OFFSET == ""
        get SIZE asize
    else
        math SIZE = NEXT_OFFSET
    endif
    math SIZE -= OFFSET
    log "" OFFSET SIZE
    math OFFSET = NEXT_OFFSET
while NEXT_OFFSET != ""

Script works flawlessly, I'll have to slowly check the file, i still can't understand if it's unpacking everything as it should be (minus extension) or... not? xD
And I'll apologize but i have to ask another favor :V
I found this .pak file into win32/64 folder, i'm too optimistic to think there's their "packer/unpacker" inside but still...

Yes, you are too optimistic.
That one is an archive for the Google Chromium engine, you can extract the files from it with this script:
