The floppy is just a visible artifact of a system that works, but is no longer easy to modify. Old systems often didn’t abstract away the implementation details of a floppy drive, so it might expect not a block storage, but rather something that actually behaves like a drive. It’s worth noting that current state-of-the-art emulation of Commodore 64 drive is still not perfect and fully compatible with all software.
