[mkgmap-dev] MapSource crash with DEM: Maybe tdb file needs changes?

Hi Gerd,

For gmaptool I have assumed following meaning of these data:
byte 0 - always 1
byte 1 - region (always 1)
byte 2 - subregion (always 0)
bytes 3-6 - always 0 1 0 0

Region and subregion are extension to family ID and product ID and are 
used for coding unlock keys.

I have replaced original TDB by a TDB created by gmaptool and map still 
crashes, so I assume these values aren't important.

Gerd, don't you have access to tdb from Adria Topo? There is Hungary 
TopoGuide available too:
