How do you edit the game to remove major status from a country ?
The only way to modify Majorpower status is to "erase" the countries you don't want to be unconquerable from a copy of the scenario-file (.eug). So if you want to play the Grand Campaign as France, wanting to annex the whole world, make a copy of the GC file and erase all countries but France from it and start your campaign from it.
5. Yeah, but I want to change this in my current savegame !
To be on the safe side:
1) First start a new campaign with your current scenario.
2) Save immediately and quite the game.
3) Make a new copy of the scenario as described above.
4) Start a new campaign with your newly edited scenario and save imediately.
5) Open up your two savefiles and incorporate all differences between the two to the savegame you originally wanted to change.
Be carefull though as even very small errors can lead to frequent crashes.
For those not wanting to do it the hard way, Graf von Bismarck, posted this condensed howto description on the German board. It's been confirmed to work by other players with 1.07C. However as future patches might change things in the savefile that might affect the correct procedure, return to the above "safe" solution if the below method doesn't work properly.
1.) Load savegame in a text editor (wordpad, ultraedit etc).
2.) At the beginning You´ll find entries for all selectable countries. Delete every entry except the one for Your own country.
3.) Using the search function, find the entries, where all the info for the various countries are listed. Those entries always begin with
country = {
tag = xxx
You´ll have to find the entries for the countries You want to be annexable now.
4.) In every such entry change the line "major = yes" to "major = no"
5.) Now, at the end of the file You´ll find entries beginning with "eyr= {" for all the selectable countries. Delete those blocks for all countries save Your own.
6.) Lastly, at the end of the file You´ll also see the entries "landtech", "navaltech", "army", "navy" and "size". You´ll have to delete the entries for the soon to be annexable countries there.
7.) Save
8.) Start a game and load the edited savegame. The countries in question should be annexable now.
