A 4am hack                   2016-12-30

Passport is a cracker's tool that can
remove several forms of copy protection
from Apple II 5.25-inch floppy disks.

Minimum system requirements:
- Apple //e, //c, IIgs, or ][+ with 64K
- Two 5.25-inch disk drives(*)

(*) fully compatible with floppy drive
emulators like CFFA3000 and FloppyEMU.

Some fun facts about copy protection:

1. Many companies, especially smaller
   ones, outsourced their copy
   protection. I have seen byte-for
   byte identical copy protection on
   disks from 7 different companies!

2. Even companies that wrote their own
   copy protection would try to re-use
   it on multiple disks to get the most
   "bang for the buck."

3. Not everything has been cracked!
   Because there was so much piracy in
   the 1980s, some people assume that
   everything ever published has been
   cracked and ultimately preserved in
   an emulator-friendly format. In
   reality, there are hundreds of disks
   that have never been cracked. Thirty
   years later, these programs are
   still trapped on physical media,
   literally rotting away.

                   ~

Using Passport is simple. After running
the program, put an original disk in
slot 6, drive 1 and a blank formatted
disk in any other drive. If necessary,
press "S" to cycle through your drives.
Then press "C" to start the cracking.

If all goes well, Passport will read
your original disk and write a copy in
a standard format, then remove any
protection checks from the copy. The
copy will boot and run just as well as
the original disk, but it will be
copyable with COPYA or any full-disk
copy program.

If all does not go well, Passport will
tell you where it all went wrong.

In any case, Passport will NEVER write
to or alter your original disk in any
way. And neither should you! Don't
reduce the number of original disks in
the world; they aren't making any more
of them.
