The eject button would become a simple touch switch, wired to the floppy disk emulator board. It would be context sensitive as well as responding differently to press and hold.

It would have a default floppy disk image (stored in a default location on the SD card) and this image is automatically "inserted" after a power on.

The Amiga (or whatever computer) would boot from this image on power on.

The default image would be many times smaller than a real disk, the "unused" portion of the disk would then be used to pass information to and from the floppy emulator. Information about the disk images stored on the SD card, disk selection etc.

The default disk image would create a simple menu, the user selects the disk image(s), the default disk image then informs the floppy disk emulator of the selection whereby it "inserts" the selected disk.

The user then reboots (either with the reset key(s) or an option in the host application) and the computer boots the selected disk image.

For multi-disk games, pressing the eject button would cycles through the selected disk images.

Press and hold returns the floppy emulator to the reset state, selects the default disk image whereby the user can then reboot and select another disk image.

The Amstard CPC does have a software controllable floppy interface. (i.e. it can send read/write commands) As do all computers AFAIK.

No, as you say that would make the product too specific. Not Generic enough.

It would require help from developers on each platform to create the default images, but they would be very simple and you could open source the developer information. If the price was right for the hardware, the developers would embrace it, writing the applications for you.
