A more elegant way to do this would be to be to create a mod that disabled the nations.

To do that create a new text document called whatever.dm

The specific code you need is:

#selectnation "Nation Number"
#era 0
#end

Do this for all the nations you want removed. The nation number corresponds with the nation numbers listed in the mod document found in the dominions folder.

You will need some header information in your mod, you can create that by using any mod as a template.

The end result is that the nations are disabled for any map without having to modify individual map files.

Goodluck!
