I have the tendency to play with my controller plugged into the fourth controller. I selected "FIGHT!" to select my character, and both P4 and P1 were available, despite me only having one controller plugged in and my Wiimote having long since turned off. Furthermore, I had control of both hands, which made starting a match pretty much impossible until I unplugged my controller and reconnected it to the P1 slot.
It's nothing game breaking; it's just quite the inconvenience.
