I always wondered about this, should be pretty easy to knock up a quick 
command line utility to splint them into 2, how complex this needs to be 
depends on how exactly the dsd is encoded.

If it has all of side 0's sectors before all of side 1's (side 0 track 
0..40/80, side 1 track 0..40/80) then it should just be a case of 
splitting the file in half, should be pretty easy to achieve with 
unix/linux/Mac OS X's dd command (or similar, under windows you should 
be able to use for example the cygwin version).

If the tracks are interleaved within the file so : side 0 track 0, side 
1 track 0 etc then whilst it's still possible to use something like dd, 
knocking up a simple command line utility to do it would be easier.

Cheers.

Phill.
