Thread: Question about tracing source code to memory

So I've been trying to figure out how this guy - http://opiumtest.blogspot.com/2010/08/h ... d-god.html - traced the cheat handler function from the source code to the memory. He looked at the source code and found the function that handles cheaters. I get that part. I also know how to NOP stuff in the memory using a hex editor. But how do you figure out where a specific portion of the code is in the memory?

Another related question: he said he "replaced the get damage_ property with a different one in the code." These aren't variables you know the value of in the game, so you can't just do a simple search in the memory for these values. How did he manage to find this stuff in the memory?

Here's a link to the game: http://www.realmofthemadgod.com/
