Programming the Nintendo Entertainment System was a 20 minute Lightning Talk that I gave at CodeStock 2014 at the UT Conference Center in Knoxville, Tennessee. If you missed the live presentation, you can see the run-through presentation that I recorded and posted to YouTube. I go into the details of 6502 assembly and how to create your own game for the classic 8-bit system. Learn how to create sprites and how to move them around on the screen. I/O is explained to obtain input from the controller.
