Hi,
We found an answer to your question and included it below.
Question:
It would be amazing if you could publish how to write our own maplet files. Ideally, mapopolis could read .gpx files. However, that will require a bit of work. If you could just let us know how the maplet files are setup, I can write a doodad that will convert a .gpx file to your format.
Thanks in advance,
Ryan Blace

Answer:
Hi Ryan,
Check back in a month or so -- our programmers are working on something here (for Pocket PC, not Palm OS).
Please let us know if you need further assistance
Thanks,
Mapopolis Support
