Persona 4 Arena: Ultimax

[Struggleton!]

I wasn't sure if I would be able to, but here it is! Fair warning, it's over 5 GB.

Alright, from looking at it, it's PS3 SEGS data. You can dump the individual segs files by using this QuickBMS script:

Code:

get FULLSIZE asize
findloc OFFSET string "segs"
for OFFSET = OFFSET < FULLSIZE
    goto OFFSET
    get DUMMY long
    findloc SIZE string "segs" ""
    if SIZE == ""
        math SIZE = FULLSIZE
    endif
    math SIZE -= OFFSET
    log "" OFFSET SIZE
    math OFFSET += SIZE
next

Then you can decompress the individual segs data using this QuickBMS script:

Code:

# AR segs archives - Arc System Works (script 0.1.3)
#   Sonic Unleashed
#   Battle Fantasia
#   BlazBlue
#   Arcana Heart 3
#   Persona 4 Arena (Ultimax)
#   ...
# script for QuickBMS http://quickbms.aluigi.org

        get SIZE short

        clog MEMORY_FILE OFFSET ZSIZE SIZE
    next i

    # pfd

endif

print "\nyou can try to reuse this script with the output files (pac, pfd and so on)\nfor extracting the other files contained in them"

Warning: Use quickbms_4gb files on this; the normal version will stop extracting files from up to 4.37GB big, but if you use the quickbms_4gb, it will extract the segs files properly.
