Added Bio Challenge by Delphine Software as another example for a game that uses the copper to add multiple color palettes to a single image resulting in very nice hue shifts throughout the image.

It's also the first time I used my WinUAE save state reader, which can read uncompressed .uss files and display the currently active screen contents by parsing all the copper lists, registers and memory. It's still pretty primitive but it can already cope with color changes via the copper list.


Bio Challenge uses the copper quite extensively to add subtle color shifts to nearly all images. The color palette is changed every 20 lines creating an image with nearly 70 colors from a bitmap with only 16 colors.
