I tried to boot my old A500 a couple of weeks ago, but the add-on hard drive, not surprisingly given its age, had some problems reading the disk.
For me the joy of reliving the heyday of the Amiga is lined to the aesthetic of the keyboard, mouse and CRT, so I was looking at something more along the lines of a floppy emulator like https://cortexamigafloppydrive.wordpress.com/ as I still have the original hardware.
edit: the comments in that review mention MiST which seems very interesting project. The board is bit more expensive, but it has an FPGA which can be configured to be an Atari or Amiga or some other retro hardware. Here is the Amiga version: http://somuch.guru/minimig/minimig-mist/
I tried it with Aros ROMs (which are open), but games were stuttering. Using closed ROMs shipped with those games (I think it's 1.2) works much better.
Hm. Looks like amiga-m68k-boot is gone from there. Not sure what happened to it.
UPDATE2: It was moved. See
"The controller allows to make dumps of your unprotected disks directly to ADF images"
At least use a Kickstart 3.0.
Still, it's a great idea and I'm seriously considering ordering one.
