I would just put the same disk image on 0 and 160, so "DRIVE 0" would always get me back. I liked the overlap because then I could copy things back and forth using the drives that appeared in both.

I'm really interested in this!  I am now starting to experiment with 
RGB-DOS (with Becker support) for the MAME emulator on the Raspberry Pi 
3.  It's working well with the VCCEmuDisk.img that's so popular. Being 
able to use multiple hard drives of 255 virtual floppy disks is 
something I'd like to try.  MAME allows you to define up to 2 hard 
drives at the same time so wondering how that might need to be configured.

I'll see if I can dig up those articles you mention.

Thanks!
