Fargo II binary compatibility notes:

* Programs which try to read the folder list (such as shells and text
  viewers) will most likely not work properly as the format has changed.
* Programs which rely on the Fargo II binary format (such as shells which
  run Fargo programs) will not work properly.
* Programs which rely on certain handle numbers (such as the IO and graph
  screens) may not work properly.
* Some RAM and ROM addresses have not been found yet.  The addresses that
  have been found, however, are adequate for almost all Fargo II programs.

Nearly all games have been found to run flawlessly under PlusShell.  However,
many other programs, such as text viewers, are not working correctly yet.
Future versions will fix some or all of these incompatibilities.

On-calculator conversion of Fargo II programs and libraries may be
implemented in a future version.
