Disinformation Decompiler

Program-Transformation.Org: The Program Transformation Wiki
Disinformation is a decompiler for Z-machine data files (Infocom or Inform), to decompile Infocom games to add rooms and objects to the game. It works best on Inform 6 (library 6/7), due to the debugging information available in such files. It can still be downloaded from the Inform Z-code tools page. The original page was at http://www.homeusers.prestel.co.uk/lwtcdi/uninform/instruct.htm, and can still be accessed from archive.org.
