Does there exist any program that can read PocketStreets files and display the static, non-GPS maps just like Microsoft PocketStreets for the PocketPC?

I've read at other parts of the forum this is somehow possible using ZRoadmap, but there were no specific details. Google likewise showed only discussion, not an actual how-to.

Microsoft MapPoint, Autoroute, and Streets & Trips 2002 and 2004 export the same format of file. This is what I'm looking for specifically: a program that'll let me use the maps I exported and display them. PocketStreets is quite good at doing this, and these maps are quite detailed.
