	Changes are committed to sourceforge. Checkout the Head (tip?) and compile. 
(Thanks Boisy!)

Syntax is:
decb dir imagefile.dsk,:1+0x52ddc
          imagename     :Drive+Offset(hex or decimal)
or
decb copy imagefile.dsk,filename:4+0x52ddc otherimage.dsk,newfile:250+339420

Use the HDBDOS offset that the image was created with. My copy of HDBDOS uses 
0x52ddc (or 339420 decimal).

Drive number is required before HDBDOS Offset. If an offset is given, every 
other 'physical sector' is skipped like HDBDOS does.

As always os9 dir -e imagefile.dsk will acces the OS9 partition at the 
beginning of the image.

Works for Me! (tm)
