Yes thank you .. I was under the impression there were 2 different glitches...
One he somehow pushes left on the d-pad while going out the screen to the right, which I have seen used on other NES games. And he winds up on the screen to the left...
The other one there is a block above him and he thrusts down with the sword and pushes to the left near the end of the animation and link goes thru the block.
So niether of these can be done in ZC? Because I noticed there was a lot of nes fixes in the menu but didn't see those.
