"It's everything on the physical disk, including the empty space between sectors, the headers and footers, and GCR 6&2 encoded data or whatever non-standard encoding the developer may have chosen. "A MOOF disk image is a bit-level representation of the disk as it's physically implemented in the floppy media," Chamberlin explains. This is fine for most software, but not all: as an anti-copying measure it wasn't unheard of for software distributors to insert deliberate errors into disks, detectable in software but not captured by byte-level imaging tools - preventing copies, or disk images loaded into an emulator, from running.

Previously, using the Floppy Emu on a Macintosh system - one of the systems supported alongside the Apple II range and the Lisa - typically required a byte-level disk image.
