I have an original controller with the gold contacts and flex circuits. I never use it as I prefer the Wico. Unfortunately my 5200 is in the shop and I cannot test it at this moment.
I have those wico sticks, trust me there are much better options if you get the clone-{getting hard to locate them now} I even have the pro sticks, none of them ever really make play very great! I have been using the clone with a sega arcade stick, the only problem is the stick is a litte weak
