This was already asked, and I explained how to do it. Take the source code and find where the narc offsets start in the different language, then re-compile with a C# editor.
That's exclusively hex-editing by hand at the moment; which narc it is is in the General ROM Info thread. Drayano has done it for his BB2VW2 hack. Structure is pretty easy to see, and I've had a ripped table for a while
