[Coco] Level3 and Drivewire may not work

[Bill Nobel]

That is true Brett, but the fact remains is that in L3 SCF and RBF are split into 2 16k banks of thier own with no communication between the 2 as I see it now.  This could in time be resolved, but I am not at that point yet.

I have converted some of them to be compatible in VCC, but not all.  I can’t figure out why on some of them.  Work perfect in raw Disk basic, but not HDBDos.
