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

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%)

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.

^^ 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)

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.

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

Path of Exile 2
In case someone ever wants to repack this..

Tiny*.bin, shadercache*.bin = oodle selkie
All others oodle hydra

bk2 files are mostly kb2j, just the big ones are kb2n.
Audio files are fmod (RIFF FEV FMT) so I don't checked them.

Use oodle library v2.9.10

I was to lazy to pack them all together with srep+fa so there is a loss in deduplication, but I cannot tell how much.
Since I have no plugin using -mhydra is the best approach to precompress this.
