RAW File Format
The RAW screenshot files found in the PICS directory are simply the RGB components of each pixel in the 640x480 window (640x480x3 = 921,600 bytes). Each color component is a byte ranging from 0 to 255 (which is in essence a 24 bit file even though Battlespire is only a 15 bit game).
