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

[Masquerade]

Beyond A Steel Sky uses ZSTD compression on the pak, but neither zstdrec nor xtool can inflate it.

Xtool:zlib will only inflate +0.44% over original size.

Any clues?

You can use the {compressor} constant (freearc constant, not inno constant) to fit multiple tools with the same packcmd into one command:

[External compressor:oodlereck, oodlrecm, oodlerecs] 
header = 0
packcmd = {compressor} e <stdin> <stdout>
unpackcmd = {compressor} d <stdin> <stdout>

Precompress the game using the Oodle core dll that the game comes with. Only some games require a different core to the one that ships (like Sekiro). Same dll used for precomp is also needed for decomp.

Here is my DSG_Settings for starfiled, is this right or not?

Data1.Name=Data1a-01.bin
Data1.InclText=*.ba2
Data1.ExclText=
Data1.Method1=xtool:mstarfield+xtool:mreflate:dd3+ LZMA-MT
Data2.Name=Data1b-01.bin
Data2.Method1=xtool:c256mb:mbk2:df20p+LZMA-MT
Data2.InclText=*.bk2
Data3.Name=Data1c-01.bin
Data3.Method1=xtool:dd3+LZM A-MT
Data3.ExclText=*.ba2|*.bk2

And what about for .bk2 files? is enough using chunk 256mb to compress it? Or i can increase the chunk size? Thank you
