What happened with its development?
After working with Miyamoto for 3 years to make Ocarina of Time they started work on Ura Zelda/Master Quest content for the 64DD.
Aonuma wanted to do a new game though and not just a remixed OoT so Miyamoto told him he could if he could finish it in only one year
so he did and we got Majora's Mask.
