Republic flag

[Nitram]

I want to give Savoy a new flag if it becomes republic and I already did the graphics, but I don't know how to put them into the game to work properly. I read tutorials about this but none told about republic flags.
Can somebody help me?

Thanks

i might be of some help. I am guessing you have to use PFM and edit the flags under UI for example; if you wanted to change Austria's republic flag you go to your Data folder, UI.pack, down to UI, flags, then look for Austria_Republic. Thats the place to edit the flags in the game. However i didnt see savoy in that file. it might be in one of the patches or if you use a modded game it might be in that mod file.

Yes I know how to change flags, I already changed a lot (Hungary and others), and yes I created savoy as a playable faction. It was a minor, unplayable one. I want to create a whole new entry, that not the same flag will come after won the revolution. Is that possible? Or is it hardcoded?
