I'm trying to create a dynasty set in modern-day Westeros. For team logos I am using house sigils lifted from the Wiki at
Westeros: The 'A Song of Ice and Fire' Domain. For unis I am picking out the colours from the logos and using the "shoulder" styles which the game generates. I have fashioned a Nation file of sorts by editing Azerbijian in the World.dat file but I am aware that this is a bit makeshift. I have d/led the Westeros file you pointed me to but they are all .csv files and I haven't the faintest idea how to convert them and insert them into OOTP14, so any help on that score would be greatly appreciated.
