3-Way Joystick Switch
The three-way switch gives added functionality for navigating in-game menus and playing games from other genres, including downloadable titles on the PlayStation Network. Easily switch between functionality for the left analog stick, right analog stick, or the default D-Pad setting.
suis je une quiche en anglais qui a mal interprété : "playing games from other genres" et pourquoi 3 way et pas 4 ? voilà ceux qui ont un de ces deux sticks pourrons surement me répondre
