Transferring Saves to and from Android

I’ve been using Son of Hunky Punk on my Kindle Fire to play through some titles (specifically Bronze, in this case.) It works great, but when I tried to transfer my save to my PC (using Dropbox), the save isn’t readable by Frotz. Anyone know how to transfer saves from Android to PC?

Do you know whether SoHP saves in Quetzal format (or whichever format Frotz uses)? If it isn’t the same format, there’s nothing to be done, I’m afraid.

I’m not sure. I’ll have to do some source diving to find out.
