New Pagan folders

[The Blind King of Bohemia]

I'm trying to give the Pagans new graphics for offices and titles so I went into 'Campmap/Pieces/Titles' and created a new folder called 'Pagan'. In there I put the new BIFS and BUFS. However, when I load up the game the Cumans still have the Christian ones. Similarly, I've tried to put battle orders from the Mongol Invasion into the game but as the game folders in 'Sounds/Battle' are named after languages (Arabic, Russian and Latin) but I can't see where its coded in the Loc folder. Can anyone help me out?

Orda had a mod a long time ago that used mongel sounds from STW for the mongels in MTW. I dont remember how he did it but I remember trying his mod Orda Horde.
