How do you make a ps2 controller connect to the PC without an adaptor?
You will need to cut the end off the controller wire, then cut
the male end of a usb wire and connect the red,yellow,black and
white wires together from both usb and controller. Then heat srink
the cut wires so nothing can touch. Then do a google search for the
needed drivers. The drivers are the most important part as without
them the controller will not work at all.
