- In my last post I spoke of FLI (Flexible Line Interlace). This is
- a method to display more colors on the screen. We all know that in an
- 8x8 squaure we are limited to 3 colors.(well 4 kinda, with the
- background color) Two of the colors are the secondary colors, and one
- is the primary color located in color ram. With this method it is
- possible to get "3" colors ber 1x4 "square" instead of 8x4. Allowing
- a total off 16 different colors to exist in the 8x4 sqaure.
- Basically this method is done by switching the seconday color ram
- every raster line. For each 8x4 sqaure, the color ram(up at $d800) is
- the same, but for each line there is a seperate seconday color.
- This method allows for some great and colorful pictures, But it takes
- alot of (computer) time and memory to display them.
