The player can skip right into the Part III section of the game by holding down B, A, and Select and then pressing start. This will lead to a screen with scrambled letters. Once the player unscrambles the message, pressing start will lead to a modified start sequence leading into Part III.
When 2015 arrived in real life, many predictions about 2015 as portrayed in the 1990 Back to the Future 2 & 3 NES game, didn't arrive, the drive in theaters were in decline and so were malls, there are no flying cars at the Drive in Theater or at the Texaco Gas Station, although there were still flying cars in the form of experimental foldable airplanes, or ducted fan flying cars, otherwise wheel cars still dominated the roads. Also, the marketable hoverboards as seen in Back to the Future 2 & 3 NES game as Marty or Biff's guards rode a hoverboard or even get a puzzle Hoverboard item which never came out. Although there are 2 wheeled self balancing hoverboards or the experimental Maglev hoverboards like the Hendo Hoverboard, or ducted fan hoverboards otherwise, there are no hoverboards as portrayed in Back to the Future II & III NES game. Also there are no futuristic buildings unless you live in the cities of Asia. However, there are camera drones, some robots models, and vintage Cafe 80s which did show up in the real world of 2015.
