      Please search for Config.ini file in the game installation, saved game data or Documents folder.

      For Assassin’s Creed Brotherhood, “ACBrotherhood.ini” is located in C:\Users\Your_User_Name\Saved Games\Assassin’s Creed Brotherhood.

      For Assassin’s Creed Unity, “ACU.ini” is located in C:\Users\Your_User_Name\Documents\Assasin’s Creed Unity.

      Once you locate the configuration file, right click it, choose Open with | Notepad.
