Norecess released a new version of his SDCard HxC Floppy Emulator Manager which works on the Amstrad CPC 464 and 664 now. If you already own a HxC floppy emulator, this tool is a must have for you.
The HxC Floppy emulator was designed to to replace the floppy disk drive by an electronic device emulating the floppy disk drive.
