OziExplorer ozf2 Composite Map with Mapsforge Base Map and Online Maps

[lonepine]

Hi

How do you create a Composite Map using either Mapsforge or Online Maps as the base map and then use a OziExplorer ozf2 Map as a top layer

using the same projection...but OziExplorer ozf2 map(s) does not come up in the Composite Map "Select a Layer to Add to Map" list

Is there another way to overlay a georeferenced (projection) image "map" (ozf2) onto Offline/Online maps
