I never used crossmac - just booted from a filedisk and added the dedicated partition for Mac side in Shapeshifter using Shapeshifter's tools and then put the Mac OS into the partition. The same partition could then be used in Fusion, too - and Basilisk. And in iFusionPPC as additional disk. But atm I think it has bit the dust - the whole SCSI disk I mean. When working it was not readable via Amiga except using Shapeshifter's tools.
