Copy protection disk

Dear All, 

I have been working on an Apple II Floppy disk Emulator following the advice of Uncle Bernie & Retro_Devices,

You can follow progresses made over the last 5 weeks of intensive work.

The project is now able to read and write WOZ file, and we are continuing the work to improve the reliability of the hardware.

 

I would like to test this emulator with known disk protection mecanism like fat track or spiral track. 

Does someone have a list of woz disk that is using such protection ? it would help me a lot to adjust the software piece and validate the current design

 

Thanks 

Vincent

Cannonball Blitz and Frogger,

Cannonball Blitz and Frogger, for example, of course find well imaged, not cracked disk images.

Here is one, but I don't

Here is one, but I don't really know the exact protection mechanism it uses:

This was a diskette containing a set of puzzle games that came with a book, written by a Bulgarian professor in the 80s. He wanted to show the games to his grandchildren, so I was part of an effort to find all surviving diskettes and produce a disk image, so it can be played on AppleWin. Most of the diskettes we found were damaged and the few that were not were protected. Retro_devices might know more about the particular protection mechanism, since he was the one who produced the .NIB.

 

Note: In order to run on AppleWin, the .NIB file must be read-only.

WOZ test disks

I recommend downloading the suite of test disks available on the AppleSauce website. There are almost 50 disk images which demonstrate different types of copy protection and aspects of the 1.0, 2.0, and 2.1 WOZ specifications, along with an explanatory readme and implementation suggestions. The download link is on this page:
