Super Mario Bros. Special

Super Mario Bros. Special is the true "lost" game of the series. It was made by Hudson Soft for the PC88 series of Japanese PCs and was officially licensed by Nintendo. SMB Special was the very first licensed sequel to Super Mario Bros. to appear, having been released a few months before The Lost Levels in 1986. While superficially very similar to the original Super Mario Bros., the game features completely original levels and lacks a screen-scrolling mechanism. Jumping and running physics also differ from the original, providing a more challenging experience than Super Mario Bros. Due to the PC88's technology being slightly inferior to that of the NES/Famicom, the graphics and audio differ slightly from the original NES game as well, although they are closely emulated.
