I tested this today... sadly, it hangs when playing from my SCSI HD and cdrom attached to the BlizzardPPC's controller, it works OK when playing from the IDE controller (FastATA MKIII), but even while playing from IDE, if I open a file or even delete a file in the SCSI HD, the mahcine doesn't freeze or anything, but the sound in the delfina goes BRRRRRRRRRRRRRRRRRRRRR... as far as I remember, this is the same behavior as with previous versions of the library :-(
I attached it to the VarI/O clock port...
