Okay I offically give up. I've tried to play this two months ago yet all I got was unreadable for RAGS. Tried again tonight and afer an hour of going through every single RAGS download there was, all I get is that it's unreadable. Unless there's something I'm missing, there's something seriously wrong
I think each version has to be added to regalia separately, but I've never used it so i'm not sure. The mod dev is a frequent visitor to that thread so post a question in there.
It works fine for me in Rags.
