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

[wareck]

Hello
there is something wrong during the pass2 (recheck)
it's more or less like a CRC error in memory during rebuild dedup
You can try another version of srep (3.2 o the 4)
Or you can try to change config:

packcmd = "srep.exe" -hash- {options} InFile OutFile

to

packcmd = "srep.exe" -hash=vmac {options} InFile OutFile

it will add some crc check in the srep file.
In some case it work with a slighty lower ratio.

thanks for the help wareck, using 3.92b fixed it.

-hash- just means there will be no crc check for srep. I added it because freearc already do this, so there is no need to make two crc checks, which will slow down things a bit.

For pathologic3 :

data1: xtool:c32mb:munity,lz4hc,l12:dd3+LOLZ_NORMAL
data2: xtool:dd3+bcm or xtool:dd3+bzip3
data3: xtool:mzlib:mpreflate+srep_new:490g+razor

there is some .bank files, can be processed outdside diskspan.
My results with the last game update 26.5gb

Is there no way to disable 2nd pass ?

Can anyone share best compression method for Stellar Blade ?

I know splitting file into multiple archives causes increase in size but how much exactly ? I splitted Black Myth Wukong into 4 and the final size is almost 102 whereas it should be around 96-97, or did i mess up some other thing? Used -d96m/128m -mtt1 -mt10 -mc1023 for lolz. Precompression as per wareck. Another thing I noticed that DODI used oo2reck+oo2recm and got to 94.95GiB with a single archive

what do you mean splitting ? cls-diskspan split archive ? or splitting the game files into different archives to use different compression on them? like this one

splitting the game files into different archives.....though i used same method for all of them just had to do because of storage

Pre-processing:

inside Paladin\Content\FMOD\Desktop you will find many .bank files.
extract all of them using bnkextr. you will find a lot of .ogg and some
other files. merge all *.ogg files into a single solid file solid.ogg using
bincat or anything else. delete the rest of the extracted files. make a
hdiff patch from solid.ogg to Paladin\Content\FMOD\Desktop without
any compression.

Archives:

• Archive 1 - Paladin\Content\Paks\Paladin-WindowsNoEditor.pak
  use oodle dll v2.9.5
  

  xtool:mermaid+kraken+srep+lolz

• Archive 2 - *.mp4 *.mov
  

  zstd, or you can use bz3 (better ratio but slower unpack)

• Archive 3 - solid.ogg
  

  oggre

• Archive 4 - diff file
  

  msc:raw:wav

• Archive 5 - everything else
  

  dispack070+delta+razor

Final Size

input       -> 11,429 MB
compressed  ->  7,620 MB

unreal engine crap.

do the usual I guess.

Here is the sample, still can't really find out what to use properly

[KaktoR]

Indiana Jones and the Great Circle
Version 12th May 2026

Library loaded: v2.9.12\oo2core_9_win64_2.dll (CRC FCBE6F2C)
Streams: 83 / 85
Patched: 0 (0,00 MB)

Library loaded: v2.9.13\oo2core_9_win64_6.dll (CRC 41AAB7C9) (from game folder)

Size: 67,8 MB >> 108 MB

It looks like v2.9.12 library is the correct one here, at least for the sample I have.

You have to specifiy oodle kraken level, otherwise precompression will took forever.
Sample: gameresources_0_hq_patch1.streamdb

xtool:mkraken,l6
Compressed 1 file, 71,132,775 => 139,054,190 bytes. Ratio 195.49%
Compression time: cpu 0.05 sec/real 6.76 sec = 1%. Speed 10.52 mB/s
All OK

xtool:mkraken
Compressed 1 file, 71,132,775 => 139,054,190 bytes. Ratio 195.49%
Compression time: cpu 0.06 sec/real 12.88 sec = 0%. Speed 5.52 mB/s
All OK

However not all streams can be processed. Either all of the libraries I have are not the correct ones or this is one of the games which requires at least two different libraries to get all streams. I guess the latter is the case here, same as in games like WWE2K19 or Elden Ring.
Because it's idtech engine it is a bit tricky here. I looked through and I don't think plugin is possible, at least not configuration based.

Edit: Looks like resources files are kraken level 4 and you need another library for these files. Like I assumed, I guess it's the same as in other games. Two different libraries for the game files. For resources files it looks like library v2.9.0 is the way to go. The library does not work for streamdb files of course.

Edit 2: Here is the deal.
