Making a flippy disk was to use the back side of a floppy when you only had a single-sided drive (like I did back in the day).
If you put a flippy disk into a double-sided drive which is expecting to read double-sided disks, you're going to have a bad day. The data on the back side of a flippy disk is written backwards compared to how it would be written on the back side by a double-sided floppy drive.
If you already have a double-sided floppy drive, then you don't have any reason to make flippy-floppies to use that second side of the floppy.
To read the second side of flippy-floppies that you already have, you use the single-sided software that wrote the disk and that only uses a single side of the floppy and flip the floppy over. Then you transfer the data to a normal double-sided floppy.

this is the right answer. i had to buy a 1541 c64 disk drive to read the back of my c64 disks
