The two analog thumb joysticks work by using a "hall effect" magnetic sensing device. Basically its a potentimeter but the whiper isn't phsically touching anything (makes for a longer lasting potentimeter). A +5 current is attached to one input, ground to the other, and the wiper in the middle is used to output the 0V to +5 volts depending upon how far the stick is pushed along one axis. When the wiper is in the middle (netural position) 2.5V is produced. Far left is 0V, far right is +5V.

: Thanks Dave but still no luck on hacking analog joystick. By the way Dave whats "Hacking the 2 analog thumb joysticks would require you to have a hall-effect type analog arcade joystick."
