Name?

There are two maps in the pack file. The first map is called minimap_naostage.jpg while the second map is called minimap_soulstream_region.jpg. Other than the file names, the maps are identical. I'm presuming that the former is the map used when meeting with Nao based on the file's name. The second map is the map used when you do anything else in the Soul Stream. Program-wise, they are two different areas. But story-wise, they are very likely the same place.
