If this has already been brought to attention, I would like to greately apologise for wasting your time.
If you're using the Wiimote Nunchuck when playing as snake with Shake Smash on, all you you have to do is smash foward and shake the stick down and up to peform a mortar slide.
Not sure if you knew this already, but I realised it the other days when I was forced by peers to use the Wiimote.
Snake is definately first pick for Wiimoting. Lol.
