Turning Scotland Pagan and adding gunpowder

Hey all,

I only want to make two changes to my game for now, and then it will be perfect in my opinion.

First, I want to change Scotland to a pagan faction. I've changed the religion to 'pagan' in 'descr-sm factions' but it hasn't seemed to make any change in the game. Is there anything else I need to do?

Also, I want to add handgunners and musketts (or at least some form of firearm unit) to Scotland. They deserve it! I heard there is a unit already pre-made but I can't find it on the forum. I'm also willing to change it by hand so that I can recruit handgunners and muskets.

Can anyone tell me how to make these simple changes or show me to a tutorial already posted?

Thanks!
Warmaster
