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

[bird2026]

Carmageddon: Rogue Shift UE4Keys : 0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E 1185E0F146D25B45 The key audit did not take place. How can I confused:mpress this game?

^
Seems to be just kraken streams, Use the Unreal plugin in xtool..
Should look like this:
xtool.exe precomp -mue5:k0x7A29E66C3CB184042A44F5E35EC023504940867C38 2D2E8E1185E0F146D25B45+kraken -c64mb -t100p -d1

 Compressing pakchunk9-Windows.pak
Compressed 1 file, 1,587,512,507 => 4,549,507,714 bytes. Ratio 286.58%
Compression time: cpu 2.83 sec/real 686.82 sec = 0%. Speed 2.31 mB/s
All OK

the vehicle I use DiskSpan_GUI V2 2.0.2.4 / I'm trying to do it, but it's not working—please help.

^ I haven't touched diskspan for a while, but this should be the method ig:

 xtool:c32mb:d1:mue5,k0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E1185E0F146D25B45:mkraken:core_2.9.10:lib_2+srep_new:392+LOLZ_NORMAL

It didn't work; I don't know why.

Could you use your own compression tool and share it with me for restoration?

Use ue4 instead.

 xtool:d1:mue4,k0x7A29E66C3CB184042A44F5E35EC023504940867C382D2E8E1185E0F146D25B45:mkraken:core_2.9.10:lib_2

If this does not work either send sample like this
Carma\Content\Paks\pakchunk16-Windows.pak

By KaktoR**, thank you for your help. My goal is to compress certain games whenever I feel like it, but sometimes I’m not sure how to do it or where to start.

Do you think this is the best option? Is it sufficient for ultra-compression, or is there a better alternative?
