I buy this controller to use with a sne emulator on a Mac . after a quick and easy set up the controller work really well . it be not as well construct as the original because it kind of feel cheap but it work well and be a good enough value to merit 4 star . btw - it work for classic ne emulation as well but I find the postion on the a and b button to be just different enough for I to splurge for a classic ne controller .
