First of all, thank you for answering back, Gedemon, I really appreciate it. I will try to be as specific as possible since you said my question was rather generic.

So, I created a map in world builder. It's focused on Europe and it is a 'large' map (96x60). My intention is to create a World War II scenario for the map. I want the names of the cities to reflect their names in 1939 (ex: Stalingrad, Königsberg, etc). I don't need to designate a name for every tile, just the ones that I will place major cities on. I will use your Closer Cities mod as well in order to fit more major cities into smaller countries.

I have already gone into WorldBuilder and gotten the coodinates I will use for the cities and created a spreadsheet with the list of the X and Y coordinates, the city name and the CityLocaleName. I was following the advice of Andre.Miksha, the creator of the CONUS mod. He used YnAMP for his own map to create the Real City Naming. He explained in a discussion on his mod what files need to be used: CityMap.xml and MapText.xml. He also explains what you need to write in the files for the Real City Naming.

The only thing is, I don't know how to convert my map into the YnAMP model, or whatever it is I need to do in order to do this. I have GitHub and Notepad++ to do the work it's just I'm lost on how to get my map to the coding like yours are. I managed to find those files for the your maps included in Yet (not) Another Maps Pack and I see how you worked there.

Thank you for your help.
