That sounds like you have no regions at all.  Which country is this?
In the UK there are only a few places that actually get a region name,
so restricting by region name is not very useful here either.

These options need to be given when you are creating the individual
img files, I've just tried it to make sure it is still working and it
does indeed give the specified name to all cities that don't already
have a region name.

They don't have any effect when creating the index, but I suppose the
region-name one could, although it would be better to provide it on
the individual tiles so that you get at least some division of the
country.

That seems a little strange. I am sure that region-name sets the
default region name and not the country name.  There is a country-name
option which you could try too.

Yes this is the basic problem.
The data we need isn't and will never be in the main OSM database.
You really need to pre-process the the data to add region information
to every POI and road using a set of polygons with the region
boundries.  There is probably something suitable out there to this.
We could do this step inside mkgmap too by adding an option to read a
file containing polyons for each region.

I will do, thanks.
