    I've never worked with it, but I think you're working backwards.

    Start from the protectee and see how it interfaces with gameguard. You'll probably be lead to a call via a static variable which will have the address of the imported routine loaded into it via GetProcAddress, dig around in there. Fasdoj sodghdfjg Once I get more time(hopefully the coming weekend) I can write an applied reverse engineering section in my article(In my sig)

    Which reminds me, I should have a section in there about delay-loaded libraries.



    There are two types of tragedies in life. One is not getting what you want, the other is getting it.

    If you wake up at a different time in a different place, could you wake up as a different person?

    GameMon.des - a separate process which interfaces with the npgamelib via named pipe.

    If your game doesn't implement CSAuth2, all you need to do is nop a call to CreateProcess and maybe a few other checks. Luckily for you, CSAuth2 is extensively documented.

    Anyways, most people use custom implementations of GetProcAddress.

    That too, if they do you need to break on read of the libraries export tables. Or just look for calls close to LoadLibraryA(which can have a custom implementation too.) In thus case you could look for APIs to allocate large memory sections.

    I always thought that the game would interface with external GG related processes and drivers via a GameGuard dll. It makes sense in a design prospective to do.
