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.
