Passport

a verification and copy program for 5.25-inch Apple II 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 protection. I have seen byte-for-byte identical copy protection on disks from seven 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, digitized, and 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.

Usage

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.

Supported protections

Passport targets common protection schemes that were reused by multiple companies. These types of protection were common in educational software.

  • Apple "Special Delivery" e.g. Ernie's Quiz, Instant Zoo

  • Blue Chip e.g. Squire, Baron, Tycoon

  • Davidson & Associates e.g. Math Blaster Plus, Read N Roll

The latest version of Passport can also recognize and defeat the protection used by some game companies. In general there was more variation and "one-off" protection in games than in educational software, so your mileage may vary.
