Okay, sorry, now that we have gotten that out of the way, here are the graphic files for the Dark Desktop that (to my knowledge), was only available via a VerdataPatcher, using a patchdata.mul file (which means those folks using UOP files were, um...S O L :| )
**I TAKE NO CREDIT FOR THIS WORK**
I know this is incomplete, and no, I'm sorry, I do not have any plans on completing the full UI (at this time). These are just the graphics that came with the Dark Desktop (the file names indicate the GumpID they are replacing).
Extract the archive to a folder (You should see 1 or 2 jpgs of
Open UOFiddler, and click on the Gumps tab.
Scroll through the list until you find the GumpID that matches the FileName.
Right-click in UOFiddler on the GumpID, and select Replace.
Navigate to the folder where you extracted the archive and select the FileName that matches the GumpID.
Right-click on the graphic and select Save (Do this after you replace each graphic, just to be SURE).
Rinse and repeat until you have replaced all the graphics you wish (you don't have to use all the graphics.)
When you are done, right-click on , and select Save one last time.
Take the gumpart.mul and the gumpidx.mul and include them in the client files for your players.*
*Those that require UOP files, use UOFiddler to convert the gumpart, and gumpidx files accordingly.
