Ok somehow I cannot close/minimize the hack window for MPGH Combat Arms Public Hack. I am currently using v 1.3 and it was the same with v 1.2. Insert/Delete key somehow doesn't work for me. I am running Windows 7 Home Premium 64 bit.
To use that hacking list you click on it when you enter the game and use up and down arrow keys to scroll through and turn on whatever you want. To start it you launch the injector(preferably PerX) and choose that dll. I always have it in the same file with the injector not to lose it haha)
I wouldn't use easy to see hacks as it's somewhat dangerous but no fog, chams, no spread and target is a great setup for a good 50 kills 5 deaths game. The target is great for sniper no scope with spread making it perfectly accurate. Do those alone and you are set to rule haha. Have fun!
If it crashes make sure you use PerX infector and latest version of the hack. If you see an update happen chances are you get a new version of the hack with it.
