Here’s a snippet to extract all the ZR zips. Copy all the zips onto your desktop and run this in a console window

for a in .zip do unzip -o $a -d <a class="zem_slink" title="Basename" href="http://en.wikipedia.org/wiki/Basename" target="_blank" rel="wikipedia">basename</a> $a .zip rm $a rm basename $a .zip/.json done

Now, each ZR zip contains the audio (as mp3s), plus a json file detailing what item ranges can be picked up during each block and with what probability. We don’t need this for what we are doing.

There’s also no telling whether or not Six to Start will start including other files within their zips, so rather than extract just the mp3s, I extract everything, then take out what I know I don’t need.
