There's not too much to it. The blue lines are the inputs - each one is labelled. The green line is the 'conveyor belt' connector, bridging the serial output of the bottom IC into the input of the top one. The red line is the 'Load' line. The always-pulsing clock line is green. There are four extra buttons not used on the 2nd chip, you can see they're not attached. Each line is held "high" by the +5v power and the 10k ohm resistor (see the [[http://www.gamesx.com/misctech/controltech.htm|Controller Primer]]) until a switch is pressed, grounding the pin. To make a NES connector, simply ignore the second IC. Please note that button 'Y' above is button 'A' on a NES. | There's not too much to it. The blue lines are the inputs - each one is labelled.
