I just checked the Logitech website. It says the Dual action has twelve buttons and the cordless rumblepad has ten. Did they really remove the L3/R3 buttons on the cordless one? I can't believe they would do such a stupid thing. Very strange.
I already have 2 of those from rockfire. I have one PS1 and one PS2 dualshock2 controller. Now I need a converter that will work with my "logitech cordless action controller" since the ones from rockfire doesn't work.
