Black Squad upk files

[rpopulik]

I can't extract Black Squad upk files using umodel. I found this topic: http://www.gildor.org/smf/index.php/topic,2459.0.html
Now I am wondering if it is possible to decrypt files somehow, maybe they are simply xored or something and it is possible to use custom bms script.
Here is startup.upk: http://www.mediafire.com/file/3z7avqzsq ... tartup.upk
If somebody could look at it, I'll be glad. Thanks in advance.

you need to post a dumped exe first, without the code that reads the upk how should anyone guess it?
