  • UOFiddler UOP Extractor plugin 0.1 – Extract UOP to MUL, Pack MUL to UOP
    • There are some who are having problems when using the RunUO’s Legacy MUL Converter to pack/unpack UOP files, so I decided to create a 3rd party GUI to help the extraction process
      Just drop the DLL into your UOFiddler plugin folder then load it
      The GUI is pretty self explanatory. It may contain some typos, sorry hehe
      The main reason I released it under Custom Artwork is that there is no specific category for 3rd party tools
      if you do not want to compile, just navitagate to “UOPPacker\obj\Debug\” inside the ZIP file and extract the “UOPPacker.dll” to your UOF plugins folder
