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

[L0v3craft]

Hi guys. I'm trying to compress the game "WUCHANG: Fallen Feathers" v1.6 (179243).

It has two pak files (one is 41.6GB and the other one 14GB).

They are encrypted but not at all seems, because simply using srep+lolz the compression ratio is very good.

So I have used srep+lolz on all game files, compressed from 56.2GB to 18.4GB.

Another repacker (Elamigos) compressed the same game version (I compared the hashes of all game files) but his repack size is 17.5GB. He included also the soundtrack in the compression (so additional 137MB of mp3).

So I opened his archive and he used like me simply srep+lolz:





Now I don't think at all it is about some parameter of lolz or srep, because my repacks and his repacks usually are the same and in some case I compress a little better. In many cases we both compressed only using srep+lolz and no difference in final size.

My srep parameters: srep64 -m3f -a2

My lolz parameters: -d256mb -dtb1 -mtt1 -tt4 -mt10 -mc1023

Someone can help me to understand, please? Thanks.
