Super Double Dragon playthrough (2 players 1 controller glitch) Nintendo Snes Game Completed HD beat

The craziness starts at 34:15, and I finished the game! A super interesting playthrough of Super Double Dragon where I control two players at the same time with one controller. At the end of level 5, I use my first continue and my character returns to the fight. Surprisingly, Player 2 joins as well and is somehow linked to my controller as Player 1. I was able to control both of them with one controller and they mimic each other perfectly. The run continues in this way up to the very end of the game. I was surprised how well it works, controlling both players at the same time doing the exact same moves. They combine attacks very well and if one is knocked down l just start playing the other. They also can hit each other, kinda crazy.
