I want to translate DayZ into a language that it's not available in. I don't care if I would be able to distribute it, or if it would be just for my own use, but I want to translate it regardless. How do I go about doing this?

If the game being able to read that new addition to the stringtable would be an issue, then instead of adding a new language to the stringtable I could just overwrite a previously existing language instead
