Finally got some time to test this, so far all adf games that have hd install option went fine, and few games that played from this floppy emulation, worked fine. Tried to create one HD floppy image for testing, but no joy. So it's just for normal 880k floppy images(?). All in all, it's an excellent piece of hardware. No matter if i have to use my PC as a host for adf files, while my A4000 shares the PC monitor anyways
Now all i need to do is, fit this inside to the amiga...
