Changing province ownership in save games

From EU3 Wiki

To change who controls a province in a save game, (notepad works with editing saved games) you first have to look for the province number of the province you are wishing to change. The Provinces come listed after the Centers of Trade which you can identify because of the 'cot' as you scroll down.

Now, a province will be listed as such:

---

} 28={

   flags={
   }
   owner="SWE"
   controller="SWE"
   core="SWE"
   core="FIN"
   culture=finnish
   religion=catholic
   capital="Borgå"
   citysize=1787.933
   garrison=1000.000
   base_tax=1.000
   manpower=1.000
   trade_goods=fish
   workshop=yes
   courthouse=yes
   fort1=yes
   history={
       owner="SWE"
       controller="SWE"
       add_core="SWE"
       add_core="FIN"
       culture=finnish
       religion=catholic
       hre=no
       base_tax=1.000
       trade_goods=fish
       manpower=1.000
       fort1=yes
       capital="Borgå"
       citysize=1020.000
       discovered_by="latin"
       discovered_by="eastern"
       1487.1.1={
           controller="REB"
       }
       1487.5.24={
           controller="SWE"
       }
       1500.1.1={
           citysize=1096.891
       }
       1510.1.1={
           citysize=1200.089
       }
       1512.1.1={
           workshop=yes
       }
       1520.1.1={
           citysize=1313.000
       }
       1530.1.1={
           citysize=1436.537
       }
       1540.1.1={
           citysize=1571.707
       }
       1545.1.1={
           courthouse=yes
       }
       1550.1.1={
           citysize=1719.598
       }
   }

Now, all you have to do is change the owner and controller, and core if you wish to have a core on the nation, from SWE to the 3 letter code of the country you wish to change it to. Say I want to change the owner to Japan, I will insert JAP into the spot where SWE is. Should look like this:

---

} 28={

   flags={
   }
   owner="JAP"
   controller="JAP"
   core="JAP"
   core="FIN"
   culture=finnish
   religion=catholic
   capital="Borgå"
   citysize=1787.933
   garrison=1000.000
   base_tax=1.000
   manpower=1.000
   trade_goods=fish
   workshop=yes
   courthouse=yes
   fort1=yes
   history={

---

It's as simple as that. And you can also do a little more tweaking with each provinces stats as well the same way.
