Star Trek 25th MAP
Files possessing the suffix .map contain the walking maps for rooms. They have been saved with a granularity of 8x1.
MAP files do not contain any header information. Instead, they are a sequence of 8000 byte values that describe the walking map (i. e. the space in a room where a game character may walk). Each byte represents a 8x1 pixel large area of the screen, starting from the top left to the bottom right line-wise. If interpreted as greyscale values, the area where a game character may walk is painted black.
