O sorry I posted some pictures in my larger bst post toward the bottom
as for southpaw it makes it where the joysticks are swap from left to right function wise where the right analog stick works as if it where on the left side and vice versa I can also do the same with the triggersw and legacy is where instead of up is up it would be up is down and down is up etc.
Also here are a few pictures of my hackball mouse to trackball interface the buttons go on the quik connects and the other end has the 6 pin molex that plugs into the trackball's molex pictures are just the raw material I will hot glue all the wires and put it in a case when done so it looks like a box with wire coming out one with the connects and the other end has the wires with molex on the end and the ps2 or usb cord is included also but not pictured.


will get more pictures if needed or some other models done.
