"Sands of Egypt" is not a Coco3 game, so that is not the issue. I can confirm it 
will not run over DW3 but gives disk I/O errors if no floppy disk system is in 
use. If there is a floppy disk system present, then Sands will try to access the 
hardware floppy rather than use the DW3 system.
That must mean Sands contains its own disk software, not a surprise as the game 
contained special copyright protection.

Given the above as an example, there must be other games which contain their own 
disk routines and therefore will not work with DW3.

Since you are using DW3, why not run an emulator such as MESS or VCC? Then you 
will be able to play Sands and other games which contain their own I/O routines.
