W1 Prototype Super Mario Bros 2 USA Gameplay.

So this game is the prototype of super mario bros 2 usa it was a very rare rom and it was very hard to emulate using emulators. There were still elements from Dream World Doki Doki Panic. Like the door potion bottle, the green bonus screen, mario with 2 button eyes and the undeground/indoor music that sound similar to super mario bros 3. #supermariobros2 #prototype #supermario #nintendomario #helpmemakethismakesense
