so, I guess you are talking about this: github (dot) com (slash) Arks-Layer (slash) PSNovaTranslations
I've been looking and the last update was 2 years ago, I did start to go through with google translate and fill in the blanks, but tbh it was too much work, I do feel like somebody with the right know how could write a script to do this.
So in short, Yes some of it works, and some is still missing. I'd be interested if you make any improvments.
