[Coco] Drivewire help needed

Mon Oct 18 18:33:46 EDT 2010

Thanks for the help everyone. I tried Rescue on Fractalus using the link 
Aaron gave me and it works great. At least now I know WHY certain games 
aren't running under drivewire. Oh well I'll either have to find a real disk 
drive (yea right) or continue using VCC for those ones.

So if those lines of code in the drivewire log window aren't checksum error 
messages, what are they supposed to mean?

Thanks again for everyone's help to someone who loves the coco but who isn't 
very technically inclined with its deeper issues.

Jeremy
