Expansion pak is required.

This is the description of the Youtube video of the download link:
Note: These are the original 64DD dungeons that Master Quest is based from. There are differences, between the layouts and puzzles. The team and I are very happy to present to you the Zelda Ocarina of Time Expansion mod. We have labored tirelessly over the gigaleak sifting through info and found the original DD layouts for the dungeons. We have ported that data and added some additions to help make the experience as complete as possible! These are some of the most challenging dungeons and we hope you enjoy them! As for the trailer, I have purposely avoided showing off most of the dungeon areas/puzzles so you can enjoy the surprise of going through them yourself. More info is in the readme included with these patches!
