I have found a way of generating .osm.pbf files that span multiple countries by using the osmconvert64-0.8.8p.exe utility. https://wiki.openstreetmap.org/wiki/Osmconvert#Parallel_Processing

Here is a batch file that converts them to .o5m files, then joins them together in a single .osm.pbf file for use with LK8000 to generate the OFF-LINE topology file for use with LKmaps. Name the batch file to what ever you like and run it with no parameters to get the correct syntax.

It's crude but effective......

@echo off
IF "%1%"=="" goto Help

set File1=%1%.osm
set File2=%2%.osm

echo osmconvert64-0.8.8p.exe %File1%.pbf -o=%File1%.o5m
start /wait osmconvert64-0.8.8p.exe %File1%.pbf -o=%a%%File1%.o5m
echo osmconvert64-0.8.8p.exe %File2%.pbf -o=%File2%.o5m
start /wait osmconvert64-0.8.8p.exe %File2%.pbf -o=%File2%.o5m

IF NOT "%5%"=="" goto FourFiles
IF NOT "%4%"=="" goto ThreeFiles
goto TwoFiles

:TwoFiles
echo Converting 2 files
set FileOutput=%3%.osm
echo osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m -o=%FileOutput%.pbf
start /wait osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m -o=%FileOutput%.pbf
goto end

:ThreeFiles
echo Converting 3 files
set File3=%3%.osm
set FileOutput=%4%.osm
echo osmconvert64-0.8.8p.exe %File3%.pbf -o=%File3%%.o5m
start /wait osmconvert64-0.8.8p.exe %File3%.pbf -o=%File3%%.o5m
echo osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m %File3%.o5m -o=%FileOutput%.pbf
start /wait osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m %File3%.o5m -o=%FileOutput%.pbf
goto end

:FourFiles
echo Converting 4 files
set File3=%3%.osm
set File4=%4%.osm
set FileOutput=%5%.osm
echo osmconvert64-0.8.8p.exe %File3%.pbf -o=%File3%.o5m
start /wait osmconvert64-0.8.8p.exe %File3%.pbf -o=%File3%.o5m
echo osmconvert64-0.8.8p.exe %File4%.pbf -o=%File4%.o5m
start /wait osmconvert64-0.8.8p.exe %File4%.pbf -o=%File4%.o5m
echo osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m %File3%.o5m %File4%.o5m -o=%FileOutput%.pbf
start /wait osmconvert64-0.8.8p.exe %File1%.o5m %File2%.o5m %File3%.o5m %File4%.o5m -o=%FileOutput%.pbf
goto end

:Help

echo Usage:- GenerateLK8000File.bat FileNameOne FilenameTwo OutputFileName [DO NOT INCLUDE FILE EXTENSIONS]

goto end

:end

I'm learning a little more about osmconvert64-0.8.8p.exe....

It takes about 18-20 minutes, but may be quicker than waiting for LKMaps Desktop to do it internally. I used this command to extract a fairly large area of France and small sections of Switzerland and Italy using coordinates, then used it for Offline Topology:-

TO EXTRACT AREA FROM LARGE MAP:-
Syntax:- InputFileName.osm.pbf -b=Southwest-Long1,Southwest-Lat1,Northwest-Long2,Northwest-Lat2 -o=Outputfile.osm.pbf

osmconvert64-0.8.8p.exe europe-latest.osm.pbf -b=1.39233,42.99538,6.86295,47.18854 -o=France-Sudx.osm.pbf

It may be much easier to use LKMaps Desktop to generate a single area covered by your two .LKM files.
