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

Better use zstd version "1.3.7", as it is stored in trine5.exe.


Although it doesn't make any sense, I looked through some of the streams in the texture archives.

#1 174760 > 174752 = 8 bytes
#2 349520 > 349504 = 16 bytes

#3 11184808 > 11184800 = 8 bytes
#4  5592400 >  5592384 = 16 bytes

#5  699048 >  699040 = 8 bytes
#6 1398096 > 1398080 = 16 bytes

#7    43688 >    43680 = 8 bytes
#8 22369616 > 22369600 = 16 bytes

Actually this is the repeating size pattern.

Signature(1),DSize(4),Unknown(8),ZstdHdr(4),Stream

This Unknown 8 bytes are actually the byte size difference for DSize. 8 and 16.
