How to put a Famicom Disk System image to a FDS original disk.
What the connection between Disk System and PC ?
Might be very hard considering FDS disks are non-standard shape so it wouldn't be like Amiga disks where you can write images onto them using your PC floppy drive. You'd probably have to build and create your own interface, in both software and hardware terms.
Something interesting I found while looking for an answer though. When the FDS reads a disk, it doesn't just access the bit it's supposed to look at, the head reads the whole disc sequentially all the way through from outside to inside, a process that takes about 6 seconds. Very interesting and odd.
