[Coco] Drivewire help needed

[Little John]

Not all games that use the DOS command are OS-9. The DOS command just reads 
track 34 into memory starting at $2600 if the first 2 chars are OS and then 
executes the code. Many non-os9 games and utilities made use of the DOS 
command to load them, but most of them could also be loaded via RUN"*" or 
some such as well. If the games are in fact OS-9 then you could dsave them 
off to a drivewire capable OS-9 boot disk and get them going.

Zenix and Crystal City would probably be difficult to get going under 
drivewire - Jeremy used his own disk access routines I think to load the 
second side of the disk.
