...would this work for games, where you'd normally boot from the floppy?
;-) Mount the floppy .adf file from within UAE, then tell UAE to re-boot the emulated Amiga. This is different to resetting UAE. It should work. Mind you, I haven't tried it myself, because none of my .adfs are games. As for swapping disk, just tell UAE to eject one, then tell it to mount the next. That's how I installed Workbench on UAE in the first place.
