I was trying to make my own PS2 controller to atari joystick adapter using Arduino and while the directionals worked perfectly I couldn't get the fire button to work. Looking into it with my trusted volltometer I noticed that the Mega outputs a 0.3V current at pin 6 every few milliseconds which means that there is always some voltage. Anyone else noticed that? Does it only happen on the Mega STE (only on mine)?
