I want some help to modify two languages in Crysis 2. I found on web that this can be done through modifying the pak files. I was able to find the file. But I am not able to edit it. I had tried various things for the same. At first when I made changes the game stopped working. It is not giving me the proper output. Fortunately I had kept the backup ready with me and I had restored the same. The game just started working. What should I do here to modify the pack files and get the right output.
