I haven't researched this carefully, but I may have inadvertently created some MP3 files that reliably induce the Hula Hoop reboot bug.

Try playing this file and see if it makes Hula Hoops reboot your Empeg.

When I tried it, it got the Empeg to reboot so many times that it reset the volume to silence and deactivated shuffle-play. I assume that's what happens when Emma has trouble saving its state to NVRAM?
