Hi! 
 
Thank you for figuring all of this out! :O
I found this thread when trying to figure out how to mod this game.
I was willing to spend a lot of time to figure it out (and still am) but then I found this thread.
It would be really awesome if we could work on this together although I have say I'm fairly new to reverse engineering games (and this forum).
 
My primary goal is to change as much from the game as I possibly can, so we could create new maps  and pictures and such.
I realize this will probably take a long time, though.
 
Kind Regards,
HiddenKnowledge
 
p.s. Sorry if my post seems slightly chaotic, I'm just so happy I found other people working on this.
