What about an expanded Balaton map, covering the capital, Budapest too?

Fairly easy to do step by step.

Step 1

Take all the *.tga files and enlarge the image to north and east by multiple of 8 pixels for map_T, multiple of 32 pixels for map_c --- Don't expand the map west and south. Keep the Southwest corner fixed.

Step 2

Extract the existing actors with mapsize.txt set to old map y value

Step 3

Recompile actors with mapsize.txt set to new map y value
There is no need to "shift" the actors because the map origin has not moved.

Thats it -- You should now have a new Balaton map with a bigger landscape area which will now appear in FMB Map Editor ----- so now extend all the rivers in map_c and start building Budapest.
The new area will all be flat, but map_h stuff can be added later.
