Notes and Comments

  • The R/G/B values within the palette have been saved in a range of 0..63.
  • Each image has been divided into several blocks (probably to make scrolling easier). The block size in pixels can be read from the header. When reading the blocks from the data, place them from the top left to the bottom right, line-wise.
