Again what is your mount command? And what were they then.

mount c c:\trazere for all of my useage of dosbox maybe 26 yrs.+
For Wizardy
mount c c:\bane or mount c c:\dsavant

ETA: I just tried both Wiz 6 and Wiz 7 and they both work, without installing either, Just trazere that is the lone standout.

OK, lets discuss what I can do. I browsed and there is a 3.5" drive with USB cable that can be purchased ~20. So, if I bought this puppy what would be the steps to install and be able to play 4 crystals?
Plug in cable to lap, say it comes up with F:
Insert Disk 1 into drive
Start DosBox
mount f F:\
F:
install
??
If that all works will the drive indicate it wants a disk in C: (which is now for dosbox terms F:)?
Does that look probable?
