you can use oggre, atleast on the file you gave me.
you have to extract the ogg files first with fsbext.

fsbext.exe -e G0KTrWjS9syqF7vVD6RaVXlFD91gMgkC 1 -d out .\sm10.fsb

this will give you a unencrypted fsb file. you have to extract it to get ogg.
after extraction merge all the ogg files at into a big blob. and
compress it using freearc oggre. but the problem is on building
the original file, as they are encrypted. maybe take a look into the source
code of fsbext.

edit:
making building the original data is fairly easy i just misunderstood it.
after extracting the ogg files, pack them using bincat and make a diffpatch
from ogg blob to the decrypted fsb file. and during installation build the
decrypted ogg file and use the same command above to encrypt it again.
it will produce same file.

Try compressing the full game at once, xtool+xbk2+srep+lolz

Hi friends,
Does anyone know how to compress dead cells?
It uses .pak files though the game is not made on unreal engine.
I tried using these two methods but no luck:
xtool:mzstd+srep_new:392+LOLZ_ULTRA
xtool:mzlib+srep+LOLZ_ULTRA
xtool:mlz4f,l10+srep_new:392+LOLZ_HIGH

Don't mind the input sizes. It's because DSG is taking input size before last call action.

Why not use zlib+reflate on both files?

If zlib fails xtool will use reflate.

[wareck]

i don't know why, reflate makes decompress fail 99% of time with the big .minizip

I used zlib+reflate so that might be the reason behind the error

[KaktoR]

Do you have a sample?

Edit: Nvm

[wareck]

they are big 36 and 46 gb
With the 4 other files no problem (I made some test)
I try to make a sample tomorow

edit: my night test zlib+reflate=> uncompress error at 30.9%
I'm doing an another test with .zip crypted in an another data
