1. Dpad is very sensitive but size is small like nintendo 3DS XL's Dpad.
2.1 I tested 9023 to LENOVO THINKPAD TABLET2(10" win8 tablet but my tablet had been upgraded to win8.1).
I tested my 9023 with ePSXe 1.9.0(window version PS1 emulator), SNES9X(window version SFC emulator) and 9023's buttons worked great except analog stick inputting.
There is no response analog stick inputting on WINDOWS
2.2 sorry.. I don't know about x360ce
3. 9023 is huge compared to PS, XBOX gamepads but very light! and 9023 has some safety catchs to fasten a tablet, so tablet is VERY VERY secured when connected with 9023.
Sorry for my poor ENG.. I'm not good at ENG
