Hi guys, can someone please help me unpack this archive? DATA_1.BIN is almost 4 GBs so that I uploaded a smaller piece of it; DATA_1.IDX possibly contains filenames & offsets for each file.

Thanks in advance, bye!

Try this

Code:

open FDDE "idx"
open FDDE "bin" 1

math FOLDERS = 0

get FILES asize
xmath FILES "FILES / (0x18   4   4)"
for i = 0 < FILES
    set PATH string ""
    for x = 0 < FOLDERS
        getarray IDX 1 x
        math x   1
        if x < FOLDERS
            getarray NEXT_IDX 1 x
        else
            math NEXT_IDX = 0x7fffffff
        endif
        if i >= IDX && i < NEXT_IDX
            getarray PATH 0 x
            break
        endif
    next

    getdstring NAME 0x18
    get OFFSET long
    get SIZE long

    # in theory only the first character, but let's do it for all
    strlen NAMESZ NAME
    for x = 0 < NAMESZ
        getvarchr TMP NAME x
        if TMP >= 0x80
            math TMP ^ 0x80
            putvarchr NAME x TMP
        endif
    next x

    string NAME p "%s/%s" PATH NAME
    if OFFSET == 0
        putarray 0 FOLDERS NAME
        putarray 1 FOLDERS SIZE
        math FOLDERS   1
    else
        math OFFSET * 0x800
        log NAME OFFSET SIZE 1
    endif
next i

Thanks, it seems to work for me.
Actually the script reported something like

Quote:

the script uses more array indexes (55) than available (55)*

but those select files I unpacked (*.mih & *.mib ones) apparently work fine. I only really needed music tracks & these are the ones I extracted using filtering option of QuickBMS.exe.

Later!

* - it seems that line #19 of your script produced the error.
