One of Super Mario 64's few remaining mysteries has been solved, thanks to a player who figured out how to open a previously "unopenable" door from the 1996 Nintendo 64 classic. We can thank a nearly four-hour YouTube video that exhaustively describes how invisible walls work in Super Mario 64, and the game's endurance for the new discovery.
