I've looked into many extractors but nothing seems to work for this. Its a Montreal .BIG file. Here is a sample of the header. The full file is 2.6GB. I can't find anything on Yeti.big that is compatible with this game.

The only script I have is http://aluigi.org/bms/lost_via_domus.bms

The sample is too small to test it.

Looks like it doesn't work fine:

Also extracted .txt file have binary garbage inside.

But most of .dat files started with 01 byte, often with 01 08.

Full yeti.big size is 2,6 Gb, and repack on rutracker is 1,9 Gb...

@Andrakann script worked correctly and there are no errors.

Code:

#   decompression not supported yet, so the script is quite useless

Is there no way to extract this Ekey ?

no, cuz there is unknown compression algorithm.

The script provides file coverage of just 33%.
Changing log "" to log NAME would give somewhat folder structure: folder 27 clearly have text content, but phrases are cut - compressed. These files could be dumped from game memory i.e. with Cheat Engine. No idea how to find models in memory. But there's always ripping way with NinjaRipper, RenderDoc.

Code:

    #get DUMMY2 long
    get num1 byte
    get grp1 byte
    get grp2 short

num1 might present some sequence number:

Code:

i   s   f   num1   grp1   grp2
89   10   10   96   56   27425
90   10   10   120   56   27425
91   10   10   121   56   27425
92   36   10   220   56   27425
93   14   10   221   56   27425
94   696   58   216   34   48928

Also executable has lots of source code (that wasn't compiled and just embed) - parts of console versions, presumably.
The game is on abandonware and archiveorg, if someone wants.
Beowulf game of same dev has yeti file as well, but, luckily, it has PSP version with all files unpacked.
