look for the post of playforbooting in this forum.. all you need to know is there..
well, you can't just experiment in hackshield folder, because when you remove any file, the hackshield and the server communicates to each other, and will detect any abnormal process of the hackshield.
and of course, when the game starts, all DLL of hackshield were injected to rf online bin, in that case, you can't modify the file or can't open it..
what i did is to make a dummy files or to fool the game that it really uses the real hackshield.
sad to say, almost all hack we know in RF are all patched and not working including hotswap, making untradable items.. though some wpe stuff works..
by the way.. I went to CHINA just to learn those stuff!! lol..
