Here is my method:
and get 21.33 gb:confused:,what's wrong with my compress method?

Did a quick and dirty check.

23.2 GB -> 18.6 GB

Maybe there is more space for improvement using oo2reck after xtool with unreal plugin, but not sure since xtool has changed alot since last posted results here.

PS: Use core 2.8.14

I'm trying to repack 9-nine-:Episode 1 and am struggling with the encryption. I was able to use GARbro to extract the resources to be at least viewable, but I can not seem to rebuild the archives to be readable by the game. I have tried using KirikiriTools to make the game read unencrypted archives, but that doesn't seem to be working, at least with the files GARbro spits out, and I can't find another way to decrypt the files to test whether or not its GARbro causing the issues in the first place.

Best method for Alone in the Dark 2024 please.

nm - this works xtool:mkraken,n256:core_2.9.9+srep_new:393b+LOLZ_N ORMAL

Unfortunately this Japanese game engine is a pain in the ass (same engine for Nekopara and a handful of other games). Maybe you could submit an issue on github that the version.dll doesn't work for the game.

Afair GARBRO should output normal png images / ogg audio which you should just be able to open normally. Getting the game to read them is a whole 'nother barrel of fish.

Unfortunately the GitHub for Kirikiri Tools is now read only. Should I just be satisfied with my 75-80% ratio I'm getting?

Unfortunate, but yes.

With new UE5 engine, they switched to oodle compression. Use this library to get all streams.

Maybe someone knows the best compression method for the MEGATON MUSASHI W game? I tried with the method: xtool:mzlib:dd3+4x4:b64mb:lzma:ultra:bt4:fb273:lc8 :mc1000000:64mb but didn't get a good ratio (39.55 of 44 gb) and sorry I couldn't upload the file for test because I confused about which file to upload. Thank You

Every file is XOR encrypted with a different key, there's almost 15 thousand keys. Each key is 4 bytes in length.

Hello, maybe someone knows the right compression method for the back 4 blood game? I checked using oo2scan_7_win64.exe and the results were using kraken and checked again using xtool.exe to find out what library was used. I have set it to versions v2.9.x & v2.8.x and none of them match. This is the file for the test:

Thank you:)

Maybe there is some zlib aswell. You should test a bit around.

Uses custom encryption algortihm.

Do anyone knows best method for this game ?
I tried xtool and oodle, but no precompress
what i miss here !

I don't understand

sorry
Got it now
thanks

Just save as ini file and use -m<ini file name>. Use lz4 library v1.9.3+

Hello
i'm working on it
for beguin I've done this:
copy/paste the text given by krator (I called it got.ini)
put this got.ini file near xtool

then I used :
for *.psarc
xtool:mgot:dd3+4x4:b64mb:lzma:ultra:bt4:fb273:lc8: mc1000000:64mb
for all other files:
xtool:mzlib:dd3+razor_stdio

I've started a test waiting compress finish.

I also find there is a lot of .wem files in music.psarc files.
Maybe can gain some other MB

^
This will not work because you have to use external configuration file for dsg.

wwise files processed: 2.86 GB -> 1.76 GB

Hi guys, first time doing this.

so i made the .ini file as KaktoR said and named it got.ini where should i place it?

and what to do about this?

If im not starting right, please let me know as well or any other advice is appreciated.

yes I extracted wem and processed with wemtool.
Then make a batch file when uncompressing
More or less like for cyberpunk..

for salamander :
you have to put the ini file in the same folder as xtool

Yep, wem processing is working well for this game.

Ghost of Tsushima

wwise extracted, processed and removed from psarc files.

I got error
I'm using DiskSpan 2.0.2.0
need to do something?

The file got.ini need to be write in the same folder of xtool.
(win64/pre/xtool)

where could I find got.ini file?

@IraqiGhost

i just made a txt document and added this to it

---
[StreamList1]
Name=got
Codec=lz4hc:l9
BigEndian=0
Signature=0x1000352415344
Structure1=Signature(7),Unk1(1),Count(4),Unk2(4),U nk3(16)
StructureN=DPos(8),CPos(8),DSize(4),CSize(4),Unk4( 1),Unk5(7)

StreamOffset=0
CompressedSize=CSize
DecompressedSize=DSize
ConditionN_1=CSize < DSize
ConditionN_2=CSize > 32
ConditionN_3=Unk4 = 3

then renamed it to got.ini (make sure to place it in the same folder as xtool.exe)

and it worked for me
then used "-mxtool:got+srep+lolz"

ScOOt3r

not work for me I don't know why
rate 100% the same size

If you're using dsg use this

Thanks a lot

anything about Hellblade 2?
which method we will use?

For .pak files, use Kraken but I don't know which library to use because none of them are compatible with v2.9. maybe someone can help? Thank You

Kraken/Hydra.

Which library to use?

Hellblade 2
 

Got this compression ratio for the .pak file on Hellblade 2: Senua's Saga
for .ucas file we need to apply UE5 compression, but require key for it.
@Kaktor, can you help in identifying the key for UE5 engine on Hellblade 2

You can use aes_finder, which you can get from a shady russian steam underground forum.

And btw, you have to use library v2.9.10 (v2) for this game.

Edit: mermaid+kraken+zlib it is

Even with the key, the .ucas file seems to be crypted as I can't get better compression than this:

^^
With that amount of zeroes, that is almost certainly not the correct AES key for this game (or any game).

Run the oodle scanner over the pak or ucas file and you will see streams appear.

This is where things are going wrong. Just use kraken and mermaid and zlib algos without any extra arguments.
