Use wemtool on them.

PS: Skip all wem file below 100kb, otherwise you will get negative ratio.

2.88mb -> 2.64mb

Edit: I extracted all audio files from the pak file and processed them with wemtool.
Result: 8.14GB -> 7.61GB

also i can see some of the files (20mb+) contains multiple bik headers. are those actual bik files and if yes are they compressable ?

^^
Check first if you can play them with bink player. Or check with Mesa.
Secondly, if they are KB2n, they are not supported by bpk.

Mewgenics
you have to extract ogg otherwise you will get crc errors on installaion that's why input size is bigger than original size (4.57GB vs 6.32GB) but output will get smaller this way (3.07GB vs 2.77GB).

Code:

 17:59:55 - Selected ARC/DS method for Data1a-01.bin was: msc_tak:mp3=0:ddsraw=0:wav=1:raw=1:bmf=9:TAK=9:bmp=1:lzma,bt4,fb128,lc8+xtool:c128mb:mzlib:reflate:dd3+4x4:b64mb:lzma:ultra:64m:bt4:fb273:lc8:mc1000000

 17:59:55 - Selected ARC/DS method for Data1b-01.bin was: oggre

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

 18:19:11 - Overall input size: 6,32 GB

 18:19:11 - Overall output size: 2,77 GB (Ratio 43.84%)

 18:19:11 - Overall conversion time: 00:19:14

they are not playable through rad video tools and bpk doesnt compress them.

cant upload the file here. uploaded it here https://gofile.io/d/HRSRjZ
i might be wrong but opening this in a hex viewer shows that it has multiple "bpk" headers.
also can you help me with compressing the .ucas file (33gb). i know i have to use xtool with ue5 method but i get 0 streams detected there. i couldnt find any aes keys in it and i tried to open the ucas in fmodel and it didnt ask for any aes keys so i think its not encrypted.

That's are just some random data. None of them are valid.

What game?

Send sample (cut 100-200mb of the ucas files). Also send exe and utoc of it.

original SHf-Windows.ucas was 31.4 gb. i cut the first 200 mb. and everything else is unchanged.

Just use mermaid+kraken

Code:

Streams: 3239 / 3240

Time: 00:00:27 (CPU 00:02:21)



Size: 200 MB >> 630 MB

this might be stupid but i still cannot get it to work.

Code:

 > xtool.exe precomp -mkraken+mermaid -c32mb -t100p-1 - - < SHf-Windows.ucas > SHf-Windows.ucas.out

XTool is created by Razor12911



Version 0.8.7



Streams: 0 / 0

Time: 00:00:00 (CPU 00:00:00)



Size: 200 MB >> 200 MB

Bro you have to use the correct oodle library!

Try v2.9.10 (2).

Code:

xtool:mkraken:mmermaid:core_2.9.10:lib_2
