How do I view zs file in tears of the kingdom

[zrzrv5]

Hi, i want to view some byml.zs file, but the toolbox cannot decompress it.

I think there was some kind of buffer size issue from what I understand. It must be some new form of Zstandard compression right?

tried to open a bfarc.zs file

I tried using a QuickBMS zs script

  offset           filesize   filename
--------------------------------------

Error: the uncompressed data (4294967294) is bigger than the allocated buffer (5604608)

Last script line before the error or that produced the error:
  11  CLog MEMORY_FILE 0 ZSIZE ZSIZE

Press RETURN to quit

For the ones that won't open, you need to open ZsDic.zs from the Pack folder, then use the *.dic files with zstd from console to unpack them

How would you do that with Font/Font.Nin_NX_NVN.bfarc.zs

I was able to unpack stuff externally with zstd, thanks to this. But i have abolutely no Idea how to make zstd in Toolbox use these dictionarys. Any reccomendations?

For anyone needing a step-by-step guide -

1. Download and unzip the latest zstd release from the ZStandard releases page.
2. Using either zstd.exe or Switch Toolbox, decompress Pack/ZsDic.pack.zs to get ZsDic.pack:
   With zstd -
   zstd --decompress ZsDic.pack.zs -o ZsDic.pack
   With Switch Toolbox -
   Tools > Compression > ZSTD > Decompress, pick ZsDic.pack.zs and save as ZsDic.pack.
3. Open ZsDic.pack in Switch-Toolbox, and extract the 3 *.zsdic dictionary files inside.

Using these dictionaries with zstd.exe, you can decompress different ZS files for use with Switch Toolbox.
For example:

• zstd --decompress Font.Nin_NX_NVN.bfarc.zs -D zs.zsdic -o Font.Nin_NX_NVN.bfarc
• zstd --decompress Bootup.Nin_NX_NVN.pack.zs -D pack.zsdic -o Bootup.Nin_NX_NVN.pack
• zstd --decompress Dungeon151_Static.bcett.byml.zs -D bcett.byml.zsdic -o Dungeon151_Static.bcett.byml

Its not the same format but does anyone know how to decompress .mc files?

[mdtauk]

• zstd --decompress Font.Nin_NX_NVN.bfarc.zs -D zs.zsdic -o Font.Nin_NX_NVN.bfarc

Thank you for posting this. Hopefully Switch Toolbox can add support for Zstd with custom dictionary in the future :D

How would I properly re-compress the file for use in ToTK?

[ArchLeaders]

You can use https://github.com/TotkMods/Totk.ZstdTool for compression and decompression

[KillzXGaming]

A fix for this has been added. Open .pack file with this tool.

Extract all the files inside into Lib/ZstdDictionaries folder of this tool.

Files will now load properly as is.

None of these tools can unpack the ZsDic.pack.zs files.
