Well, even if you change names, classes, functions etc. of "d3d9.dll" it won't help you that much. This dll its just a hook that everyone use it, you can recode the d3d9 hook, but I don't think you'll do that. I suggest you to costumize your own "mod_sa" its really easy to learn. All you need is Visual Studio and C++ minimum knowledge. You can get the open source from HERE. Or if you are to lazy to code, you can get an external hack, which 100% will bypass that Anti-Cheat Check when you join the server.
