Unsure, I have checked with latest ZSTD to see if it can list info about the archives, yet it can only seem to load info for few archives. Yet, all files are definitely compressed with zstd.

Code:

for %f in (*.arc) do zstd -l "%f"
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
     1      0     9.25 MB      30.19 MB  3.263   None  common.arc
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
     1      0   690.86 KB    1748.36 KB  2.531   None  info.arc
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
File "init.arc" not compressed by zstd
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
File "lang1.arc" not compressed by zstd
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
File "lang2.arc" not compressed by zstd
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
File "param.arc" not compressed by zstd
Frames  Skips  Compressed  Uncompressed  Ratio  Check  Filename
File "stream.arc" not compressed by zstd

I even tried compressing a demo file with zstd and testing the latest libzstd to see if the precompressor worked, neither zstdrec or xtool could precompress a random file compressed with latest zstd.

Yes, the first file contains just 1 block with zstd (28B52FFD).

However, ratio with lzma2 for init.arc is about 70%.

I will investigate it further

You can use the following tools to extract all of the compressed ZSTD streams from NieR replicant. It will allow for decompression of 99% of streams.

1. VGM Toolbox and this script. Download latest zstd.exe.

2. Place the XML file in plugins\AdvancedCutter folder of VGMToolbox.

3. Open VGMToolbox, go to Misc. Tools > Extraction Tools > Generic > Advanced Cutter

4. From the drop down menu in the top right, select NieRReplicant and click LOAD.

5. Next, you can drop each of the arc files into the top left box and it will extract the streams. You only really need to do this for the large arc files. No need on the little ones.

6. After extracting the streams, run this python script for each of the files. This will remove the extra padding bytes (@) that the devs added so that each stream begins at an offset of divisible by 16. ZSTD will not decompress files that contain data after the end of the stream.

Code:

for %f in (*.MSQ) do trimmer.py "%f"

Ignore that it involves .MSQ extension. You can switch it to .TMP or whatever.

7.

Code:

for /r %f in (*.MSQ) do zstd -d "%f" -o "%~df%~pf%~nf.DEC"

This will use zstd to decompress the streams. Afair it fails on about 16 streams out of ~7800, but you can decompress most of the game this way.

KaktoR , you are right!I tried with both ue4dt & xtool without success!
So ? What's should i use for better compression ?

KaktoR · #**2606** 26-10-2021, 08:21

I think the files are not compressed anyway, but I have not checked further.
