About adding language

[jens]

I think the menu uses the languages listed in base_x.lang. So you would have to add Korean to the languages listed in all the base lang files and then put korean.lang and base_korean.lang next to the other lang files. That should work.

So if you want to make a mod out of this, I think you would have to include all the modified lang files + the new Korean files to make it work as any other language.
