So long hesitation whether I referred this to amazon or not, but since the amazon stock are exhausted and that the price in the market other vendors are just mind-blowing (the same price as the gamecube controller even more expensive OO) I decided to keep it and go to the D system, therefore screwdriver and elbow grease, after a simple comparison with the L button I notice that the piece for attaching the R button is defective too wide (at least 3mm more ) so it creates a play on the position of the button that begins to float. One piece solution of cardboard and scotch + I filled the void after some trying to determine the correct thickness of cardboard and hop a part of Smash bros just Nickel !!!!!
Well my experience does not allow me to judge the median product quality because I'm falling on a product "defective" but looking more closely the bowels of the beast that seems in good order. I keep the joystick to the girlfriend or the son of the poet who has never tried (or for the poet not like that ^^) and I will invest in the adapter when I had my back with my GC joysticks parents.
voilou.
