I'm doing an another test with .zip crypted in an another data

xtool:mzlib:mpreflate:dd3 works fine.

I don't know why you guys having so much trouble here.

Precompressed zip and minizip together

[KaktoR]

use zlib+preflate then. for preflate you don't have to specifiy level, although it is a bit slower then reflate.

The same procedure as in every other ue5 game.

I'm trying to compress Lego Batman Legacy of the Dark Knight, but I'm getting an "out of memory" error in Diskspan GUI.

Tried these methods (*.utoc, *.cas):

xtool:t100p:c32mb:d1:mue5,k0x70390692DBC072E5C6D97 DB6D54F6977BFC8B0B273C6C1E004CEEB30BD47822C:mkrake n:core_2.9.11+srep_new:393+lolz:mtt1:mt12

xtool:t100p:c32mb:d1:mue5,k0x70390692DBC072E5C6D97 DB6D54F6977BFC8B0B273C6C1E004CEEB30BD47822C:mkrake n:core_2.9.11+srep_new:392+lolz:mtt1:mt12

xtool:t100p:c16mb:d1:mue5,k0x70390692DBC072E5C6D97 DB6D54F6977BFC8B0B273C6C1E004CEEB30BD47822C:mkrake n:core_2.9.11+srep_new:393+lolz:mtt1:mt12

Should I set it to 0? I have 32 GB of ram and 12 threads.

If the error happens on precompression use it like this

xtool:lm:t100p:c32mb:d1:mue5,k0x70390692DBC072E5C6D97 DB6D54F6977BFC8B0B273C6C1E004CEEB30BD47822C

If the error happens on srep/lolz use other options for those, like lower cpu thread usage and/or chunk size.

For *.utoc, *.ucas and *.pak:

xtool:c32mb:mue5:mmermaid:core_2.9.0+srep_new:393a+lolz

For rest of the files:

srep_new:393a+lolz

It has no encryption so no key is needed.

Total War Warhammer 3
This is using sort of zstd (maybe zstdsharp).
You can use zstd with level 22 but you won't be able to get all streams. Use the latest zstd library.

Streams: 96220 / 207465 (61,23%)
Patched: 96220 (126 MB)

-s option

Is using lz4hc so plugin required.
Idk if encryption is used like in Hitman WoA.

Do you know how I can decrypt the key? I think it's encrypted.

Use reflate/preflate

The pak file also contains 3mb of wave files and 875mb of ogg files.

 * wav     :        8, (3'117'860, 2.97 MB, 0.15%)
 * ogg     :     2463, (918'137'045, 875.60 MB, 44.32%)

Edit: Use png preprocessor+reflate/preflate as the file contains many png images.

 * png     :     1894, (1'052'939'729, 1004.16 MB, 50.83%)
 * wav     :        8, (3'117'860, 2.97 MB, 0.15%)
 * ogg     :     2463, (918'137'045, 875.60 MB, 44.32%)
 * Total   :     4365, (1'974'194'634, 1882.74 MB, 95.29%)

Streams: 3917 / 3917 (50,83%)

You can extract ogg with mesa.
Then use xtool erase function to remove the files from the pak file.
After installation use xtool decode function + created xtl file to move the files back into the pak file.

For .ogg files:

oggre+4x4:b32mb:lzma:ultra:bt4:fb273:lc8:mc1000000:32mb

For the rest of the files:

xtool:mzlib+srep_new:392+LOLZ_ULTRA

Input: 3.4 GB
Output: 920 MB

[Spinneret94]

^^ Thanks
Also is it possible to use xtool decode and xtl you mentioned on diskspan gui?
Or shall I only use png preprocessor with reflate/preflate to get some desent ratio? (Expecting 1.4-1.5GB)

[KaktoR]

In this case you have to work with CallBefore.bat and make a batch for installer aswell.

There are plenty examples in Database folder in DSG.
