The Shadow Warrior (1993 Beta) Background Image Format is used to store an unused background image, presumably to be used as a parallaxed sky texture. It is not actually used in the game, although a variation of it can be found in the 1994-05-23 prototype build[1].


There is no signature, but there must be four files (one for each plane), each of 32,100 bytes in size.

File format

Each file is a raw 428x75 VGA image, 8bpp. The first file is DAT type 130 (so if using Camoto, it is extracted with a .130 filename extension) and this contains the data for plane 1. Type 131 is plane 2, 132 is plane 3 and 133 is plane 4. The pixels in the final image are arranged as follows, where each number represents the plane that pixel comes from:

1 2 3 4 1 2 3 4 ...
1 2 3 4 1 2 3 4 ...

The pixels are stored left to right, top to bottom, in each file.
