I was just wondering what the average time it takes to the fill the screen? My implementation writes one register at a time with the value of -1. At the rate it's going, it would take 5-10 minutes to fill the screen.
Ah! This had me scratching me head for a while. I could not figure out how I could expect to black out the screen in response to a user pressing a key, when it was taking soooo long to paint. Forums have had all the answers I need so far :-) Haven't had this much fun since college!
