I've built an opensource GreaseWeazle floppy reader and trying to read/decode and encode/write BK floppies usinf FluxEngine software.
Unfortunately it seems FluxEngine decoder unable to decode some of my weared floppies and the FluxEngine encoder can not write correct data from existing image to new BK floppies :(
It will be cool to have an utility to debug and rescue old BK floppies using open source GreaseWeazle reader hardware or using flux data readed by open source FluxEngine. Also to write floppies from raw images...
