How bad is the lag on bluetooth? I have the first 2.4 G 8bitdo SNES pad. It was fine for SNES mini and for usb to pc. But I needed a pad to connect to real SNES hardware. I was thinking of the new 2.4G pad above. But it was not available. So I bought the 8bitdo BT snes pad and the blue tooth retro receiver. Haven't had chance to test out the BT yet.
