I am working on a new filesystem, to allow the mounting of Sega Dreamcast virtual memory unit (VMU) volumes: would you be willing to test it?

You do not need to use a Dreamcast to test it. It should mount VMU volumes via loopback - I can supply a 'blank' VMU volume file for testing. – adrianmcmenamin Dec 27 '11 at 18:37
