Dynamic Effect Data (ded)

Using IDA, it is possible to change what file is loaded (filenames for loading are located around the 0x00B70xxxregion).

Specifies values for lighting color, fog and fog color in the scene. It is possible to change the color of the scene ambient lighting, the fog position (?) and the color of the fog itself by modifying values directly in memory. Note that this file type only defines the intensities of the colors, not the RGB values themselves.

This is only applicable for SILENT HILL 3, as there is different colours/types of fog. In SILENT HILL 2, there are only two types of areas; those that are in (grey) fog, and those that are not.
