Nintendo 64 non oem, Legend of Zelda Majora's Mask video game cartridge.

The Legend of Zelda: Majora's Mask is a direct sequel to Ocarina of Time. 

• Three-Day Cycle: Players have 72 in-game hours (about 54 real-time minutes) to prevent the Moon from crashing. Link must repeatedly reset this cycle using the "Song of Time".
• Mask System: There are 24 collectible masks, including three core Transformation Masks (Deku, Goron, and Zora) that physically change Link's form and abilities.
• Atmosphere: It is widely cited as the darkest entry in the franchise, dealing with heavy themes of grief, loss, and existential dread.
• Hardware: It was one of only two N64 games to require the Expansion Pak accessory for its enhanced graphics and complex NPC schedules.
