Is that a Gotek USB floppy emulator on the side? Looks very similar to the ones I used to mod for Commodore Amigas to replace the internal floppy drive. Can you play ROMs from it?
.Those floppy emulators are awesome!.
From what I have gathered, this unit can load roms from floppy, and there is supposed to be some sort of sotware and tool for it but unfortunately I don't have it
