^ You'll find all the text-based translation work we did for this awhile back at the above link. I'm not sure how much of it you already have translated yourself, but it might boost your progress some. You're welcome to use all, some, or none of it. Your choice.
I also had all the map images translated. I'm not sure if I still have them saved somewhere. I'll look for them and if I find them I'll upload it somewhere for you to use if you want to.
Best of luck with the project.
