I still don't understand, how to get md5 hash of my client bro ?
this is client feature. You need just diff your game client. (please check NEMO)
"Force Send Client Hash" - working from 2010-07-** game exe - up to current clients.
I already diff, my mean i want to know how to know my 'md5 hash number' client @@
After diff client, i want to protect it ( want everyone have to use it, if not will show error or can't connect ), because if normal, everyone can put their client to my ro folder and run with their client !
