THE DISK WAS COPIED SUCCESSFULLY, BUT
PASSPORT DID NOT APPLY ANY PATCHES.

POSSIBLE REASONS:
- THE SOURCE DISK IS NOT COPY PROTECTED.
- THE TARGET DISK WORKS WITHOUT PATCHES.
- THE DISK USES AN UNKNOWN PROTECTION,
  AND PASSPORT CAN NOT HELP ANY FURTHER.

The original disk is very lightly
protected. They changed one epilogue
byte on the one sector where it's
ignored anyway (since it's read by the
disk controller ROM routine, which
doesn't verify epilogue bytes). This
renders it uncopyable by COPYA and
other sector-based copiers, and they
didn't need to make any changes to the
rest of the disk. It's literally the
least they could do.

Quod erat liberandum.
