A strange case of being two games at once for the second cardinal installment of the Mario platforming franchise, due to the American release of the 2 title putting out something different:
The Japanese version, referred to as Super Mario Bros. 2: The Lost Levels
The American version, a reskin of the NES game Yume Koujou: Doki Doki Panic. Referred to as Super Mario Bros. USA in Japan.
