Correct me if I'm wrong, but when you inject a DLL, its treated as part of the .exe file, so if you write any memory it will actually write it to that file, am I right?
And very nice tutorial wiccaan. Smile

When you inject into a processes memory, thats all you are injecting into. It's memory. It wont write anything to the game file(s). (Some games however can get effected by editing memory which will cause things to get written in files such as saved games and so on.)

Thanks as well. Smile

Umm no? This had nothing to do with inline asm.
