Hello i'm searching for any advices on how to decompile .cas files, i saw different posts on the Xentax forum but i cant access it, if anyone have knowledge about this, it could be cool 😃

 

Thanks !

Can you upload some sample files? What game are they from?

They are from the Beta version of Skate 4 which is not released yet

Here's one of the two .cas file from the file : https://www.mediafire.com/file/koagbix6xh1ayaa/cas_02.cas/file

I did some research and i found out that a .toc file was also doing something in the process when i launch the game, if anyone have a bit of knowledge on Frostbite Engine it would be great since i'm stuck 😄

// 010 template
BigEndian();
int desSize;
ushort unk;
ushort comSize;
byte ZstdBuffer[comSize];

zstd compression in cas

toc file contains offset, size, file index and a few important things but may be encrypted

Hey,

What Template is that?
