Ran across this Chinese program over a forum.
We all know these .ext files are hidden within the .pak files.
the only thing I don't know is that if editing these .ext files will actually effect the actual ingame, or if things are purely server-sided ( which I think is the cause )
but with the amount of hacks running around the chinese DN, I wouldn't doubt if there's a simple way to create these hacks. If the chinese can do it.. we can do it better.
Anywhere, here's the .ext editor, do what you will with them.
You can test your stuff on the private DNserver (yes, this server is completely legit ), since the closed beta is over for NA.
