[Trumanator]

I am trying to finish a mod my friend wrote when he borrowed dominions for a while, but I am having some issues.
At first the mod had no sacred units, so I modded the #holy command in on a couple units, and it worked. However, when I tried to add a priest, he wouldn't show up in the recruitment screen. I don't currently have a way to do sprites, so I was trying to just clone one of the other commander sprites from the nation, but it would not show up. I am also trying to reduce the resources on a couple of the units, but I can't seem to make it work. I have tried changing the units' #rcost, their armor's #rcost, and their weapons' #rcost. What am I doing wrong? Do I need to change the version number?

Also, I would appreciate it if people would tell me what programs they use to edit and view sprites.
