I am non native english speaker but I'm willing to improve.
- Don't overwrite file. If you just want to add new things.
~Don't use a file name that is the same with original file.example: Japan Ship name mods
when create new file at "MOD_FOLDER_NAME"\common\units\names_ships\
Use name like: "MyMod"_ship_names
Not : JAP_ship_names
then in MyMod_ship_name write
for_countries = { JAP }
if you want to use with only japan.
- still not sure how the file work. It feel like the game read whatever in those folder regardless the tag name
example: MyMod_ship_name -work. It not neccessary to be like "COUNTRY TAG"_ship_name (i.e. JAP_ship_names)
- the Uppercase code is likely to be used on some other files.
example: JAP_SS_HISTORICAL = { name = NAME_THEME_HISTORICAL_SUBMARINES ... } NAME_THEME_HISTORICAL_SUBMARINES used on localisation files
