if Link has charged the spin attack, he can walk across water in 1266. He can only do this in the axis he's entered the water at, though. If he moves perpendicular to this, he'll drown or go into swimming mode as usual.
1266: Charged Link can walk across water
Additionally, this may be caused by more than just being charged. I've managed to walk straight across water without it. This may have something to do with 8-directional movement.
OK.... fixed.
