This is really a direct question for Mastatabs, but I thought that I'd throw it out to the general public incase someone else knows.
How does the Picasso IV (or any other RTG card with integrated automon) determine when to switch between RTG and Amiga native?
Is it software, through a driver?
Or more likely hardware, perhaps simple chroma keying? i.e. Sample pixels of the native output over several frames and if they are not always colour X switch to native? (I guess if it were that simple the side effects would have been seen by now)
Just curious for a minimig related enhancement.
