I really like videos that teach me a ton of things for something I'm never ever going to use.

This was really enjoyable, thanks.

I wrote a C program a few years ago to make an image copy of DOS floppy disks. This was so I could preserve bootable floppies. (It doesn't deal with copy protected disks.)

It's a DOS program itself because it uses DOS to access the FAT tables. So it needs to run on Windows XP or earlier, or use a DOS box.

I can put it up on github if anyone wants it.

Cool video! Too bad it doesn't go in the details of copy protection. What they were doing those days was truly devious and hellish :-) (and hacking them was even more :-) )

So a modern Copy II PC Option Board.

This is a great example of a YouTube video that should have been an article.
