2.6.0 leviathan

2.9.0 kraken

I'm nothing if not stubborn, well at least with that information I've got something to go off of, I'll see what I can do.

Hey guys. Is there any suggested method for ARMA III?

AFAIK half of this game is RSA encrypted ,so it cannot be recompressed (EBO)

PBOs maybe some kind of LZO?!

Then how Fitgirl compressed it from 146GB to 73GB?

Because she decrypted it... duh.

IMHO its impossible ! RSA is asymmetric. So u can obtain the decryption key from the game ,but reencrypt...?! Only the devs knows the encryption key (Maybe its buried accidentally somewhere in a gamefile )...
Or am i wrong ?

btw Masquerade's answer seems good....

Edit:

Maybe start looking here :

You can rip voiceovers from audio1.fbq in Trine 5 using this QuickBMS script:

Code:

get VERSION long

if VERSION <= 3

    comtype zstd

else

    comtype lz4

endif

get FILES long

get BASE_OFF long

math BASE_OFF += 0xc

for i = 0 < FILES

    get NAME string

    get OFFSET long

    get NOZIP byte

    get SIZE long

    get ZSIZE long

    get CRC long

    math OFFSET += BASE_OFF

    if NOZIP == 4

        clog NAME OFFSET ZSIZE SIZE

    else

        log NAME OFFSET SIZE

    endif

next i

Made by eaZy41 from XeNTaX community.

Although comtype LZ4 is mentioned, Trine 5 uses only ZSTD and you can use libzstd v1.3.7 (v1.3.6 also seems to work). LZ4 is used on older versions of the FBQ archive structure.

Better use zstd version "1.3.7", as it is stored in trine5.exe.

Although it doesn't make any sense, I looked through some of the streams in the texture archives.

Code:

#1 174760 > 174752 = 8 bytes

#2 349520 > 349504 = 16 bytes



#3 11184808 > 11184800 = 8 bytes

#4  5592400 >  5592384 = 16 bytes



#5  699048 >  699040 = 8 bytes

#6 1398096 > 1398080 = 16 bytes



#7    43688 >    43680 = 8 bytes

#8 22369616 > 22369600 = 16 bytes

Actually this is the repeating size pattern.

Code:

Signature(1),DSize(4),Unknown(8),ZstdHdr(4),Stream

This Unknown 8 bytes are actually the byte size difference for DSize. 8 and 16.

Did your archive decompress alright? I'm getting this error from XTool when trying to decompress my archive:
I was using libzstd v1.3.7.

Code:

same, xtool just crash on unpack with 1.3.7 zstd lib
"ERROR: write error (disk full?) in compression algorithm zstd" in arc

edit.
1.3.5,1.3.6,1.3.7 - error (crash)

(don't use -dd#, it is bugged in dev build)

I made quickly made this the other day, not sure if it works very well.

Yes it works fine here using libzstd v1.3.7, but tbh I am using the development version of xtool since days, there were some fixes.

Extracting could take a while because of zstd l22 btw.
