Having a look at this, it's slow going at moment. Just trying to get the .xml updated to current standards, no clue yet if it'll even load or how bad a state the graphics will be in.
Original author had bad habit of copying files he didn't change, so I'm deleting files so it just pulls them from /default/
When/if I get something that loads I'll update.
Edit:
Try
this it's very rough (no guarantee it'll actually load, haven't had chance to test it) but it *should* load and I think I have got it at least RoF compatible.
No idea what the graphics look like, I'm not the artistic type :P
Put this in a new folder in \uifiles\ and see what happens.
Edit:
Updated the inventory window.
zip file updated
