OpenGOAL's controller layer always answered "plugged in", with a comment saying so: pretend we always have a controller connected. In Jak X, choose two players with one pad and the game moved on to player two's car select, where it waited forever for a player who was not there. On the console, the game stops you first and asks for a second DUALSHOCK. Since October 4th, Phaethon does too.
