Re: Write Only One Track

Helps detecting if a submitted dump is from a disk that was mastered using KryoFlux. And people have already been selling counterfeit originals on ebay.

Re: Need advice on how to recover 5.25" floppy

There is a way to create raw stream files from standard nonprotected DOS disk .img imagefiles using HxCFloppy software and then writing from those using KryoFlux.

Re: IBM PC disk-based copy protection schemes and games

The main issue is the vast amount of different protections. KryoFlux originally started with the Amiga in mind and the technicalities of protections used there are quite well known. Next came the C64 and handling of major protections were added to the main software. Now Apple/Atari/PC/etc. came when...

Re: Strangeness when creating MFM image files

Was suspecting something like that as after generating the image myself they went different after the first track and were different until 720k mark.

What are the options you're using, or how are converting the dump to a disk imagefile?

Re: USB Interface/Controller for original DISK II Apple

Disk II probably could be interfaced but you'd atleast need some microcontroller inbetween to translate the control signals. I guess the only direct solution currently available is the Applesauce board which does more or less the same, but compared to KryoFlux, you'll lose the track-to-index synchro...

Re: Need advice on how to recover 5.25" floppy

Yes, seem to be onesided disk.

The scatter plot in the UI can be used to check if a side has any content. If there are 2-4 distinct well separated horizontal lines visible on a track it must have something written on it. Just a kind of a vertical gradient all around the track is just noise.
