CityZen is a rather aged bit of software and doesn't run well on PalmOS devices manufactured in the 21st century.
Recompiling it for modern devices is not a trivial matter as it does all sorts of horrible non-standard things based on assumptions about the hardware inside old Palm machines. These assumptions are no longer true which is why it won't run on modern devices.
I am considering producing an updated version to take advantages of the increased power of todays handheld computers and/or phones. Possible features include using a proper spherical projection, drawing coloured maps and having the ability to add customised overlays of your own data.
A while ago, I built a prototype system to explore how much processing power would be required to handle drawing a true spherical projection akin to a real atlas. Assuming you have the appropriate Java technology in your web browser, you can play with it here.
In order to produce something like this for PalmOS systems, I would of course need a shiny new-fangled handheld machine. If you want to give one to me, let me know!
