There are definitely chinese sourse code for server somewhere in the internet. All private servers for dmo (bbdmo, dmw) are using Tdmo or TWdmo file system(Thailand folder in pack03 in dmw/bbdmo had pack06 or pack02 instead of normal pack03).

UPD.
It is possible to use private server clients with Bradley server. You can inject your ip with cheat engine in the game. The game tryes to connect, but server give this errors(sorry for half russian errors).
If we update server to newer game code, then we certanly can play this with new content.
I am not programmer myself, but i will try something.
I am used DMW client for this. DMW guys, i am sorry, but sciense requires sacrifices.
