Explanations for Graphic Formats:

  - "(Int.)" means that the corresponding type of memory is interlaced.
  - "(FLI)" means that the Graphics mode uses FLI. The number of Screen-RAMs
    determines how often FLI needs to be achieved.
     E.g., 8 Screen-RAMs = every raster-line
           4 Screen-RAMs = every second raster-line...
  - "Hires" or "Multicolor" pixels define the type like Bit 4 of $D016.
  - "X-Shifting" means toggling Bit 0 of $D016 between frames.
  - "Background-Color per scanline" means you have to set $D021
     every rasterline.
  - Detailed infos about Sprite Layers still need to be done.
