[EDIT] - unfortunately, I've kinda forgotten which of the various "Panther tweaked" files were done in order to reconcile/eliminate some potential conflicts with the RFB files as opposed to some other mod's files, so some of these may require some manual intervention to make them "play nice" with RFB - your best bet would probably be just to try them with RFB and let JSGME tell you if there are any conflicts - if they're just some graphics files then you can generally let them over-write the RFB files, but it they're the .ini or .cfg type files then you'll probably need to do some manual integration (or maybe use the new JtxE tool I've seen referenced lately but haven't had a chance to try yet) or else you might lose some good RFB stuff if you just let the new one over-write the RFB one.
