[Coco] Will Dragon 32 Cassette software work on a coco?

[jeremy michea]

I have a friend in the UK with some older dragon 32 cassettes, mostly 
games I believe that he's willing to send me but I don't know if I 
should have him bother if they won't work on a coco. For example he has 
Katerpiller Attack which is I believe the Dragon 32 version of the Tom 
Mix Coco game. Any insights on compatibility in this case?
