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.
|
|
|
|

|
|
|
|
Passport targets common protection
|
|
schemes that were reused by multiple
|
|
companies. These types of protection
|
|
were common on educational software,
|
|
not blockbuster arcade games.

|
