Having looked at the source code, I now think this may not be a bug but 
a nomenclature problem. I'm not quite sure yet.

The makefile for the Level2 modules contains
# VDGInt Modules
covdg.io: covdg.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $< -aCOCO2=1

covdg_small.io: covdg.asm
	$(AS) $(AFLAGS) $(ASOUT)$@ $<

Now if the only difference between covdg.io and covdg_small.io is the 
presence of Coco1 or 2 specific code, of course it won't work with a Coco3.

Let's have some programmers look closely at the NitrOS-9 Level2 
covdg.asm source code.
