Passport deprotects side A without any
additional patches. Track $22 is
unreadable because that was the
protection track checked by the code
on side B (now patched).

A quick note on the loading screen that
says "Flip disk over and hit <RETURN>":
it is visibly corrupted. The corruption
also shows up when booting the original
disk on real hardware. Two separate
flux images show that the disk itself
has no physical damage. Furthermore,
the flux images confirm that all
sectors on the disk were written at the
same time, which rules out user-
initiated damage. The disk was mastered
and shipped with this data corruption.

We also know from classic cracks that
there is at least one later build
(2.2/126) which fixes the corrupted
loading screen. So it seems that the
publisher was aware of it but unable to
fix it before shipping this version.

Quod erat liberandum.
