Here's a program I made to unpack the data file from Deep Voyage. To use it, just run it, making sure you have everything extracted from the Zip file. It is released under the GNU GPLv3, though I'm not quite sure on the terms of the support program it uses.

A bit of history on this: I originally started this about half a week after Deep Voyage was given away. However, because of a really annoying glitch in the programming language (AutoIt 3), about 50 files can't be extracted. So after that, I gave up on it. However, I've thought about trying to extract data from this again, so I restarted the programming and, instead of using the way I was using, I tried a slightly different method. A bit extra code, but it got the job done. I finally conquered the data pak.
