descr_cultures.txt

Has anyone tried to edit data/descr_cultures.txt files found in 1.3 and bi? There is one for each.

i made papal states culture northern european no probs but the first diplomat isnt n european style

Yes that is a commonly edited file, used to either add custom settlement/port/fort models to the campaign map and/or to add a 7th culture to the game.

I have not got this in my 1.1 version of Rome, can I add this text file and use it ?

Patch the game to 1.5.
