ROM corruption of Super Mario Brothers Special (PC-8801)

Super Mario Brothers Special is a sequel to the original game, made by Hudson for the NEC PC-8801 and the Sharp X1 computers in 1986 and is actually licensed by Nintendo. I'm using the PC-8801 version. More informations: http://www.mariowiki.com/Super_Mario_... 23 iterations.
