I tried erasing the sector header for 20/02 to see if it would fool the protection, but it doesn't work. The protection checks that some of the sector was written (first 6 bytes at the minimum must match). : : Unless someone can think of a way to damage the sector in an image to the extent that a U2 write command will only partially work, this won't function in an emulator. : : And unless you can physically damage a real disk at the right spot, this won't work remastered either. : : On the other hand, it's an easy crack to remove the protection check entirely. There's only one little method used to hide it (check $179F in the main program for the self-modifying code that hides the protection check at $17A2). -- [/quote]
