Good find dark_lord_zagato!
When mapping Battletoads (NES), I remember finding the map data for stage 13 (final boss) under the starting screen of stage 11, which is why that map has a dark square to obscure the area.
The Immortal (Apple IIGS) also has multiple stages sharing maps. When inside a room, you see the shapes of the rooms around it and when assembling all of these outlines together, I noticed that for example, stages 1 and 2 share a map, and so do 3 and 4, as well as 5, 6 and 7.
As always, it's something I never made much progress with so I never posted anything.
