I'm looking for existing tools to decrypt and unpack Mercedes-Benz Truck Racing SYN files. I tried Game Extractor and Dragon UnPACKer but they don't support file decryption. The SYN files have data encryption.

I've put some info on the wiki https://rewiki.miraheze.org/wiki/Synetic_GmbH_SYN
(Everything except decryption method :D :D )

Encrypted files seems to have !SSM signature.

LZSS compressed

use script to extract content from SYN files from this game

syn_extract.py needs Python 3.6+

whole tree - walks *.SYN recursively

python syn_extract.py mercedesbenztruckracing_syn extracted

one archive; output dir defaults to "extracted" beside the input

python syn_extract.py Textures/Textures.SYN

explicit destination

python syn_extract.py Cockpit/Textures/Textures.SYN /tmp/cockpit-tex

syn_extract.py
