The second film in the Back to the Future trilogy was turned into a side-scrolling platform adventure for the Super Famicom, released in 1993 under the title Super Back to the Future Part II, but it never got released outside of Japan.
However, it would seem that originally it was supposed to be a very different game. Video game preservation outlet Gaming Alexandria found out from old Famitsu magazines that the game had a RPG style before turning into a 2D, hoverboard-focused platformer.
