Defining cities and countries in 1.43

[Snowlovsyou]

Hello everyone. I was making a standalone map, but I stumbled into a problem. Defining cities and countries. The method used for 1.40+, no longer works on 1.43. I looked up some tutorials on YT, but most date back to 1.40 or before, or the video is poorly explained. Can someone help me? thanks in advance

The logic remained the same. Only thing new is that the file extension of the city files is now .sui instead of .sii. though the city def still remains .sii.

So:

def/city.mymod.sii
def/city/cityname1.sui
def/city/cityname2.sui
def/city/cityname3.sui
...
