.Contains no streams at all, so you don't need to use a precompressor.

Overall, you can't rip anything out with the modding tools.

Most of you guys might have known about this but i still wanted to share it.

Edit : Upon testing, here are the results. GFS didn't detected any streams though.

precomp_mtx :
Compressed 4 files, 75,380,736 => 84,305,014 bytes. Ratio 111.84%
Compression time: cpu 0.11 sec/real 5.13 sec = 2%. Speed 14.69 mB/s
All OK

ZTool : Compressed 4 files, 75,380,736 => 84,394,635 bytes. Ratio 111.96%
Compression time: cpu 0.17 sec/real 14.04 sec = 1%. Speed 5.37 mB/s
All OK

Reflate : Compressed 4 files, 75,380,736 => 84,426,712 bytes. Ratio 112.00%
Compression time: cpu 0.11 sec/real 3.77 sec = 3%. Speed 19.98 mB/s
All OK

Preflate : Compressed 4 files, 75,380,736 => 84,480,615 bytes. Ratio 112.07%
Compression time: cpu 0.11 sec/real 4.35 sec = 3%. Speed 17.34 mB/s
All OK

Edit 2 : Nevermind, don't use a precompressor, i.e because i think only the one or two of above files contained streams and other files are either .usm or pck and some other extensions.

Game uses LZSS (custom)?

Hexagon123

It does?

Well in any case, I am already done with this Title.

base & virtualtextures

xtool_zlib+srep+lzma

Everything Else

srep+lzma

Final Size: 57.4 GB
Compressed Size: 42 GB

Notes:
I tried bpk with the video files it always threw errors for me.

Valkyria Chronicles (+Update 3/DLC)
srep+lzma on movies only, srep+lolz on everything else.

Output size: 15 GB / 15.1 GB (I got 15.1 GB in the end because I had to split a file due to an error in decompression, but originally it was 15 GB.)

Side note: The movies take up 14 GB of the game, and the games entire size is 19.88 GB, so that's a lot for movies. They're .SFDs too, so there is barely any compression, which is why I advised to use LZMA instead of LOLZ, because it's much faster, and there isn't much a difference in size. You can split the .SFDs open to get the .m1v and .mp2 files with VGMtoolbox, so it's probably possible to re-encode the files, but I have no idea how to get past the 4000 kbps bitrate limit, when the raw m1v was 10000+kbps, nor do I know how to put them back together into an SFD.

Far Cry 3 + Far Cry 3 Blood Dragon (RUS+ENG)

*.dat, *.fat - Xtool 0.3.20(fc3.xtl)+srep+lolz
10.8 gb > 16 gb > 10 gb > 4.9 gb

Rest files - srep+lolz
250 mb > 33 mb

Install time = 7 min. SSD, R5 3600

xtool_zlib+srep+lolz

21GB ---> 11.8GB

[Carldric Clement]

Original Size: 101.16 MB
Compressed Size: 39.14 MB

Option :

Image : lepton
Audio : oggre -s3
Rest of the files : xprecomp+srep:m3f:a2+exe2+lolz:d128m:mt4

XTool used : ZLib, Reflate, LZ4

Note: You need to unpack the Main.pak where it should be able to compressed the rest of all files.

UPDATE: it seems this error may have been brought on by my virtual machine's virtio storage drivers, and not the fault of software used for packing.

Has anyone given the "Attack on Titan" video-game series a shot? There are a fair few zlib streams, however attempting to use either xtool 2019 or 2020 always results in a "-1" error output (which I honestly have no clue what that error-code means) after all streams have been found.

[:( Sad8669]

I do have the game but too lazy to give it a shot xD

[Masquerade]

Attack on Titan 2 works fine with old xtool v12

Could you tell me which zstd library version you used?
