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

[infovs]

If some kind soul can reveal method used for Monster Hunter Rise .pak files? Can't figure this one out...only two .pak files should be encrypted and with zlib and zstd streams but there is no AES key for this anywhere and using xtool on this will produce only small gain...but I saw few repackers ratio was *much* better. Tried creating database also but without luck.
Thanks in advance, regards.

zstd.

Use xtool 0.8.4 + libzstd 1.1.4

Streams: 77311 / 77311
Time: 00:05:06 (CPU 00:01:06)

Size: 34.5 GB >> 48.2 GB

Done!!!

Actually there are even some zlib streams.

Streams: 20756 / 20756
Time: 00:03:52 (CPU 00:14:47)

Size: 34.5 GB >> 36.0 GB

Done!!!

^you're right KaktoR, I was using most recent version of libzstd without any success but using 1.1.4 from 2017 worked like a charm! If I may ask, how can one pinpoint exact version of libzstd to use? I tried everything, yes I even tried different versions of libzstd but it never occurred to me that I should be using 7 years old dll version
Thanks again,
best regards

Never seen a ReEngine game use anything else but libzstd.dll v1.1.4 when zstd is used by that engine.

Hi, anyone know what best compression method for tekken 8? Thank you

[KaktoR]

kraken

Edit: + mermaid actually

TEKKEN 8

87GB ---> 65.6GB

*.usm
xtool (dd5 + fast lzma2)

everything else:

xtool (mermaid + kraken + dd5) + fast lolz (detection on but smaller dictionary and some fast bytes)

Used oodle core v2.9.5 (crc c0554aa2).

You can maybe cut a little smaller by using bcm (multithreaded cls) on the videos, but decompression time will be severley increased.

sorry if I didn't read your post, I used the same compression method as your post but the result was an error. maybe you know what causes the error? This is the compression method I use: xtool:mkraken:mermaid:core_2.9.15+xtool:dd3+4x4:b6 4mb:lzma:ultra:64m:bt4:fb273:lc8:mc1000000. Thank you

Which version and settings for srep are you using for Cities Skylines 2? On second pass levelerror=XXXXXXXXX. Srep version and his settings doesn't matter. ZSTDRec or XTool - too.

While the old initial game version worked just fine, I got problems with the new game version 1.1.0.F1.

Then I thought maybe new xtool version was the problem (do not wanted to blame Razor for that lol) so then I tested all xtool versions back to 0.7.9, same error. But then I remembered a problem a while ago about this game with some srep errors, so then I tested just precompressing and srep afterwards. While xtool did not gave me any error messages about srep, I tested srep instead of xtool dedup with srep.exe and this error appears:

Compressing 176,993,820,246 bytes with "srep.exe" -hash- -m3f InFile OutFile
Errorlevel=-1073741819
100.0%
ERROR: general (de)compression error in srep

If using xtool's dd feature using srep.exe, I got no error message at all but compressed data was corrupted like this:

60 GB input  -> 7 GB output, Ratio 11.67%

I even tested all different srep versions I have but all the same. Then I remembered another game where srep had big problems aswell. So after testing a bit again further with the new game version, I found out you have just to use FA's internally old rep before using srep, which will look something like this then:

xtool:zstd+rep+srep+...

Log

Initial version (xtool:zstd:dd3+4x4:lzma)
Overall input size: 55,63 GB
Overall output size: 34,48 GB (Ratio 61.97%)

Version 1.1.0.F1 (xtool:zstd+rep+srep+4x4:lzma)
Overall input size: 59.34 GB
Overall output size: 36.59 GB (Ratio 61.66%)

Extraction time about 20 minutes.

I hope this helps.
