 Since a MAP file ([1984-01-10.map](1984-01-10.map)) exists as well, it is automatically appended to the JSON file
 ([1984-01-10.json](1984-01-10.json)) when using a ROM input file (or JSON output file) with a matching filename.

 by adding *--format=rom* to the command-line (the default is *--format=json*).
 
 These operations can only be performed using the *FileDump* command-line interface; the *FileDump* API does not support
 either the *merge* option or the appending of MAP data.  For the moment, the API can only dump unadorned ROM images; eg:
