FileForums - Best Compression Methods for 'Specific' Games. Q&A

Then add zlib precompressor, srep and lolz.

Devs were nasty and put videos inside the pak with compression and encryption. Sounds are also encrypted but you should just be able to patch the encrypted data out using QuickBMS + Unreal script to print a filelist which will give you the locations of the different sound banks.

So, ue4 decrypt with key

but i don't know, if use Diskpan GUI @cesar

I think all *.pak is encrypted but not compressed.

CLS-SREP will decompress srep data no matter which version of srep you use for compression.

Make sure you use the latest version of CLS-SREP. I'm assuming you're using ProFrager's version and not Razor's version. The latest CRCs of those files are:

Code:

    File: CLS-SREP_X64.EXE

  CRC-32: ae1cd4f0



    File: CLS-SREP.DLL

  CRC-32: d30b67ba

Too many SREP versions. Any variants, not compatible from decompression, in vice-versa packed in SREP 3.2 or SREP 3.90/3.9x during in compression. Any case, not unpackaeble these data package via ProFrager's 0.33 version or any CLS-based copy's. Native bigger EXE's ~99.99% its works. (Official Bulat's release or "SR" iconized newest version EXE its solved in more problems.)

These X64.exe found from "cls_srep_v0.03b.rar" and "ISArcEx v0.4 + Test.rar" files. Two package contains X86 version EXE and not running from XP! Used bytepaching and its is OK! These DLL file, totally missing, some tools available various versions, (UltraArc, MC 20.xx, CIU3.0.x.x or more..) this different, not found the "d30b67ba" CRC-32 hashed copy.

UPD: These versions cls filter, not fully stable from cancelling installation process, these X64 (ae1cd4f0) or patched X86 EXE crashing now, from process terminating. Original full EXE or Profrager's DLL its betterly stable. (except not supported compression methods in get decompression error.) Its probably incorrect CLS-SREP.dll file attached in the "ae1cd4f0" hashed X64 EXE file in some repacking tools archives. Checked my DVD's from any archived repacking tools, not found! The DLL its available in many recompressor package tools sets?

Here is the file list, so you don't have to create this :D

Beware, the file is 300mb in size, so open it could take a while

^^

You can use -f filter in quickbms so it will only list files that you want.

e.g.

Code:

QuickBMS -l -f *.pck <bms> <pak> >> filelist.txt

P.S. don't rip voiceovers entirely because game will crash without them. Just patch them out to speed lolz up.

im not sure what or you did but i didnt get anywhere close to 30.8 GB my repack was 39.0 GB

i used this method:
ue4d:key=E01312D26CAD1529142D3ACA6DB25D4091C1AAFE0 C91E5DC104C36A768DB1E50+xtoolx+srep+lolz <- xtoolx in this cause was unreal.dll

thanks

American Truck Simulator [v.1.45.3.26s + All DLCs]

Code:

xzlib+srep+lolz

Latest XTool used with -mzlib only (no reflate).
Use -lm due to incredibly huge streams being decompressed.
I have 64GB of memory so I used a 1024mb chunk size.

10.7GB ----> 6.1GB

 21:28:17 - Overall conversion time: 02:45:51

-------------------------------------------------------------------------------------------------------------------------------------------

 22:03:03 - All files have been successfully extracted!

Paks are using lz4hc with level 9 and some reflate streams.
However not all lz4 streams can be processed.
To get a good amount of streams set --diff=20p in arc.ini (the sweatspot is somewhere between 15p and 20p, I used 20p. Above this you will get negative ratios on some files. The higher #p, the more negative ratio) and use xdelta3_dll.dll near xtool.exe

Due to false detection by xtool use preflate, not reflate. If you use reflate you will get crc errors on extraction.
For xtl creation use lspk.bms and in bms2xtl.ini set lz4=lz4hc:l9
Use liblz4 180
