Version 1.5.9                                   17 September 2018                                   md3serial(1)

       Md3serial  allows  the  serial number on program discs distributed by Creative Technology (or image files
       made from such discs) to be viewed or changed.

       The authors of MicroDesign have placed it in the public domain and explicitly given  permission  for  the
       copy-protection system to be reverse- engineered.
