Hello, sorry if I ask again. how to compress ghostwire tokyo game? I have copied gwtokyo.xtl, gwtokyo.key & oo2core_7_win64.dll into the Resources\PRE\XTool_2020\Plugins folder and I checked in the DSG in the Xtool 2020 plugin section and ghostwire tokyo doesn't appear. Thank You

I think you do not need them. Use unreal plugin with aes key + kraken + zlib + 512mb chunk size. And I think this game use a v2.8.x oodle library.

can you help me to check this game? I have checked this using oo2scan_7_win64.exe and only the 4.28 gb size has kraken and I have also checked using xtool.exe and set the checker library to oodle ver v2.8.x & v2.9.x and nothing suitable

You won't be able to scan for streams bevause this game's data is encrypted. KaktoR has told you everything you need to know.

Here is my method:

xtool:c512mb:d1:mue4,k0xC26CC5659A24AE8635585C8687 DCE552A205DBD72DC4AA0CBE187C60D88921E2:mzlib+xtool :c512mb:xtool:mkraken:core_2.8.4:dd3+4x4:b64mb:lzm a:ultra:bt4:fb273:lc8:mc1000000:64mb

and get 21.33 gb,what's wrong with my compress method?

[KaktoR]

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.

Library loaded: oo2core_9_win64_2.dll

Streams: 1512 / 1512
Time: 00:00:12 (CPU 00:00:22)

Size: 81.1 MB >> 96.1 MB

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.
