Guys,

Keep in mind that Cave Walker and other level1 games at best use Level1V2.00. 
I've tested a stock L1V2 system disk with VCC (any version) and OS-9 will freeze 
when asking you to insert the date/time. The same disk will run with MESS and a 
real Coco3. It will even run with a Drivewire HDBDOS ROM on a Coco3 from a 
hardware floppy.

As an experiment, you can almost get Cave Walker to run on VCC if you delete or 
rename CMDS/setime, preventing setime from running. You will see a WHAT? as OS-9 
starts and then the program will start. Unfortunately, when you get to the main 
screen, you will see only the background and not your player.
In short, VCC with L1V2 seems to be unable to accept data from the keyboard.

It may be possible to change some modules in the L1V2 OS9Boot file so that it 
will work with VCC. Better would be to "correct" VCC.
