I need to crack some .exe from an old game, cause a guy made an unofficial anticheat, he modified the official .exe of this game and he blocked all third party applications, it means you cant execute aimbot or cheats, all we play this game need to download 2 files. (.exe and .dll) and remplace original files. if you ask why i just dont keep playing with original files its cuz i play wars (team vs team) everyone need to have this unofficial anticheat to play, and when you press "F1" in game, it shows who have anticheat on. I heard about OLLYDBG to do this, but Sincerely
im a little noob, and i dont know where or what is the variable to enable third party applications on game. Some help?
