Mega Man 1 Block Trick

This is on real hardware/ av out on the first model of the nes. Was just messing around with the game when I noticed this. You can get the block to wrap around to the bottom of the screen at certain parts of the game! Never tried or knew about this before.
And yes I'm fully aware of twitch speedrunners. And that they probably found this trick already. But just thought I would post for fun. The video isn't meant to be super high quality or anything either.
