After 1,471 Days, I beat the Oldest Unbeaten Mario Level

I beat a level that no one had ever been able to finish for over 4 years. It was insanely difficult.
Also on another note, since me beating this level, the next oldest unbeaten levels turned 4 years old, but when I beat this level over a week before uploading this video, this was indeed the only unbeaten level older than 4 years. Also the thumbnail shows a final jump that is exactly the same difficulty and set-up as the actual final jump, without distracting decorations for simplicity.
