I've been looking into my save file, and I've determined how to transform feats into other feats, items into other items, psi powers into other psi powers, but its all a little messy. I'd really like it if someone actually started to work on a save editor (I'd do it myself if I had an inkling of what I'm doing for programming) to take out some of the mess and streamline it.
If anyone is interested in trying, I'll gladly tell what I know.
