FFS SOMBODY RESPOND PLEASE

Hey, how are you?

You don't always have inject the files, just extract the file into C:\Nexon\Combat Arms\Game
But just remember to make copies of the file, because if you do it this way you need to redo it every time Nexon patches hacks.

I do need ot injct this one, It says inject into chars t body, because its the file for the chars t, I need a tut or someone to tell me how to inject it in

EDIT: AN ENTIRE HOUR CAN SOMEONE FRIEKING HELP ME!
