@Nguyenthaonhi I use wireless Xbox 360 controllers. They are really cheap to pick up used and I use them with a USB wireless adapter. Very easy to configure. The stock dpad is crap but I did a very simple mod that essentially adds a thin plastic spacer to the back side of the dpad and it makes the dpad much tighter and more responsive.

Never mind, worked it out! I had put the clock and latch the wrong way round! Swapped them over and it all started to work (except the start putton for some reason?!)

@thrillho87 I had no issues passing wire through the pins.

@NintendoFan64 buy a usb wifi adapter
