I did further testing for my Ps3 / PC Controller. Yes, Dual Mod integration works fine. Just connect a padhacked xbox360 cg pad similar to the UPCB and connect a switch for the usb datalines.
now you can switch with the black switcher between xbox360 and ps3.
Size comparsion to the Chutulu. My realization is a little bit smaller and has better dual mod support. Sure, no complaints against Chutulu. It's a fine piece of hw.
