Origo Engine archives

[onelove1210]

Hi, there are archives from Origo Engine. They are compressed with header OPAK. I think that is a modified version of PAK0. Please you guys can help me with those files Any help would be appreciated

Sample files:
.cha - contains character files: www.mediafire.com/?eb5reobm6nwrfru
.mdl - contains model files: www.mediafire.com/?blxe9tj4bj0cgt2

Unfortunately the first 0x1000 bytes of type 1 archives are encrypted and so it's not possible to parse the files covered in this part of the header (about 60 files depending by the length of their names).
Another bad thing about type 1 is that most of the folders don't seem to have a name, they have a sort of 32bit hash at their place... you will get what I mean when you look at the folders and some parts of the names of the extracted files

So do you need DLL or exe files to find out if there is any way to decrypt ?

Ok, it doesn't matter. I think this game maybe from China so that's why their names contain lots of special characters
