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

[ozerune]

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.

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:

Uses custom encryption algortihm.

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

I don't understand

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

Streams: 3414 / 3414

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
