MM Debug: Memory Viewer

Like in Ocarina of Time, certain button combinations on the second controller allow you to edit the game's memory. Some settings are the same from OoT, just with a different variable name. Others are unique to Majora's Mask, like the cel-shading rendering mode. Note that the order of the buttons is actually significant in Majora's Mask.
