Creating a multi-line Voyager in fact would require writing new firmware; the existing DM-1x machines run the original ROMs in emulated hardware. Being able to display additional lines would require lots of changes and the source code is not available, so it's virtually impossible to do. A nice idea though.

The whole point is that it wouldn't need any firmware change. The contents of the X,Y and Z registers will be visible to the emulator, all you need to do is display them.
