v4 supports reading a whole SSD or DSD image using the "G" command. It 
doesn't support sending an SSD or DSD image to the beeb.

SSD/DSD is just a sector dump of a DNFS format whole disc. I wrote a simple 
program to add a single file to an SSD/DSD image before I knew about BBC 
Explorer, it's at ftp.knackered.org/pub/angus/BBC/addfile.zip, with source 
code. It should build for Linux and Windows, you can rip out the catalogue 
extraction code and turn it into a file extractor easily. I might be able to 
give a hand if you're stuck.
