Sunday evening arrived. Leo was determined to beat Super Mario Bros: The Lost Levels (a hack on the cart that was impossibly hard). He had finally reached the end of a particularly brutal water level.

Why does it hold such a special place in gamers' hearts? And, most importantly, how do you legally and safely experience this monster of compilation today?
