Executing

Alright, i'll make this quick.
I need a way that edits an MMOG game so it launches an anti-cheat program that someone's coded.
So basically, for that, i'll need to call ShellExecute in olly.
But i don't know how.

Could anyone tell me a way to edit my Game's. exe so it makes it launch my anti-cheat?

Game: Gunz.exe
Server: SGunz.

You can do code injection and a lot of other things, but uhm i don't think this what these forums are about. There are plenty of tutorials on how to edit an executable file.

As an examples lets say we have an executable that can only load one instance of it, simply check for string reference checking for instances. Double click it, then some brackets and stuff will appear select them and fill them with NOPs then save the executable as a different one of course ;) And kazaam we have multiple executable !!!

Obviously that is simple example of using OllyDBG but what your question appears to be about is a little unacceptable in my mind, if a mod says otherwise ill surely help you :)
