Readme

Majora’s Mask Randomizer is a Windows application that randomizes item locations, music, and more for Majora’s Mask, presenting millions of combinations and new ways to replay the game.

A video tutorial of setting up MMR is found here: https://www.youtube.com/watch?v=4woEtyg7GyM

Currently the UI is only available on windows, it is broken in wine. The CLI version works if you install dotnet and run the CLI as “dotnet MMR.CLI.dll -input <MM.z64> [-seed seed]” but modifying the settings means modifying the settings.json by hand. A replacement webui is in development which will supply a UI on all platforms.

Additional information on every feature of MMR is available by reading the tooltip shown by hovering the mouse over the option, or reading the detailed manual by pressing F1, or visiting the help menu.

MMR has no unique emulator requirements, you can play a randomized rom with any method that allows you to play a MM rom. MMR roms work on N64 emulators, they can be played on N64 hardware with everdrive and similar flashcard technology, and they can be played on Wii Virtual Console, MMR will even convert the randomized rom to a wad for you.

Known Quirks of MMR

In vanilla MM, you use [Garo’s Mask] to convince the ghost to summon a tree and grant you Ikana Canyon access, but in vanilla MM, he will also accept you wearing a [Gibdo Mask] and grant you Ikana access. Most people don’t know this because you get the Gibdo mask after getting access to the soaring owl and you never need to travel east up that cliff again if you don’t want to, but MMR accepts both masks as giving you access.

There is a hidden (bomb-able) grotto on the way to the Goron Racetrack entrance, it is surrounded by 3 snowballs. If you do not have Goron you can still get up there: There is a Scarecrow near the boulder blocking the racetrack. Call it out using the Scarecrow song, then use the Hookshot.

The Clock Town Great Fairy gives you two items in vanilla (magic as Deku, GFMask as Link) and in Rando she still gives two items, you have to visit her twice; once as Link and once as any other race (Deku/Goron/Zora). You can visit her twice on the same 3 day cycle, just leave her cave and transform then immediately visit her again to get the second item.

Unlike OOT, you can NOT have bombchus without a bomb bag.

The Romani Ranch mini-game with Romani where you would normally get Epona's Song in vanilla does NOT require a bow. You are given a bow when you initiate the mini-game and once completing the mini-game, you will no longer have it. Logic can expect you to do this song/item check without the bow because of this behavior.

The cows in Romani Ranch cannot be milked during the day, you must milk them in the barn at night from 6 pm up until the Aliens event starts with Romani. If you save the ranch, then the cows can be milked night 2 as well as night 3. However, night 3 you have much more limited time as the barn will close at 8 pm.

It is a common misconception that you need the Romani's Mask to be able to go into the Milk Bar to give Madame Aroma the Letter to Mama while wearing Kafei's Mask. You do not. The Milk Bar is open at 6 pm until 9 pm, the randomizer will logically expect you to be able to go in there at 6 pm without the Romani's Mask to deliver the Letter to Mama to Madame Aroma with Kafei's Mask.

Due to the quirks of randomization and getting items out of order, the Kafei Questline is quite a mess. The requirements for each check is listed below:

-Midnight Meeting: While wearing the Kafei's Mask, speak with Anju anytime after 2:15 pm until 8:30 pm (without Room Key/Deku Mask) to set up this event. If you have Room Key/Deku Mask, you have a little bit more time to catch her before she goes into the Staff Room at 9 pm. Once you have set this event up, you can meet up with Anju at midnight and onward, all the way until it's about to turn to the next day. You do NOT need to be there RIGHT at midnight.

-Meeting with Kafei: It is a common misconception, due to the order of the events in the vanilla game, that you need to meet with Anju to be able to turn in the Letter to Kafei to then meet with Kafei and have all of those flags set. You do NOT need to meet with Anju to do the Meeting with Kafei checks. How does it work? Simply turn in the Letter to Kafei into a mailbox anytime between Day 1 and the morning of Day 2. If you are strapped on time, you realized too late that you missed the Letter to Kafei window do not fret. The window is pretty wide! As long as you turn in the Letter into the mailbox right in front of the Laundry Pool, you have about until 11:15 am on Day 2 to get the letter in. As long as you turn it into THAT specific mailbox, it will count as delivered, and you can talk to Kafei as early as 4 pm and as late as 9 pm. Just like Midnight Meeting, you can Song of Double Time to skip right to Day 2 6 pm and go into his Hideout to speak with him instead of using Granny in Stock Pot Inn.

Additionally, there are two more checks you can get from turning in Letter to Kafei. Once you've spoken with Kafei, exit out of the hideout and then simply Song of Double Time to Day 3, 6 pm. Turn back around, go back inside the hideout and speak to the man that's standing there where Kafei was the day before. You will receive two more items. These are the Keaton Mask and Letter to Mama checks specifically. Please note; these checks can only be acquired as long as you have not rescued the Bomb Grandma from Sakon in North Clock Town on Night 1.

-Couple's Mask: Finally, due to the out of order sequence of items of this questline obtaining the final item can be confusing. More or less, you follow the same steps as above BUT once you've turned in the Letter to Kafei it is 100% valid to go and show Anju the Pendant of Memories BEFORE you talk to Kafei. The order here doesn't matter as the vanilla game doesn't check for if you've talked to Kafei to turn in the Pendant and this behavior has not changed in the randomizer. Therefore, you can show Anju the Pendant on Day 2 and she will respond to it; if you want to play it extra safe you can meet with Kafei first at 4 pm and then rush over to Stock Pot Inn and show Anju the Pendant. She WILL be standing at the desk at that time. Part of the issue is where she is on Day 3 and Night 3 if you wait that long.

Once you've turned in the Pendant to Anju and have talked to Kafei (whatever order you chose to do that in), you can safely go to Ikana Canyon. Provided you have Ikana access, which again requires Hookshot, Garo OR Gibdo Mask. Upon arriving at Ikana Canyon, proceed down to the ravine and follow it up towards the Ikana Canyon Scrub. Get behind the small set of rocks and play Song of Double Time to Night 3 6 pm. If you have Stone Mask, feel free to put it on if you want to feel safer but otherwise the rocks will cover you up while Sakon shows up at about 6:30 pm to open the hideout. Now once you're inside Sakon's Hideout, simply perform the sequence to save the Sun Mask and then go meet with Anju back at Stock Pot Inn to receive your Couple's Mask item/check.

There are other sequences like this that are done out of order but this is the biggest questline that causes confusion so it needed to be clarified and mentioned here.

For other known quirks caused more by the items being shuffled about randomly, feel free to ask further questions in our Discord or search through it as the answer is very likely to be found in there.

Warnings

Majora's Mask Randomizer has various features that are unique to itself that other randomizers might not include. These specific settings being referred to here are called "Gimmicks", in the MMR generator. These "Gimmicks" are not all treated equally, some of them can lead to softlocks and other various known issues. These issues have gone unfixed because they are largely avoidable as long as you know about them. In addition, these "Gimmicks" were essentially designed with the idea in mind that they are mostly glorified cheat codes without having to use cheat codes but built-in to the randomizer and even some of them come with logic attached.

The "Gimmicks" to be aware of that are likely to result in softlocks are Fierce Deity's Mask Anywhere and Giant's Mask Anywhere. Though, the randomizer development team has strived to fix as many of the softlocks these 2 settings cause, there's just too many specifically with Giant's Mask Anywhere that it's unreasonable to fix. Just know that when playing with Giant's Mask Anywhere, if Giant Link is going to touch the ceiling you're likely to have issues. For the most part, Fierce Deity's Mask Anywhere is fine in the current randomizer but there are still some small issues you can run into. One such example is, if you pick up a sword upgrade while in FD form you will infinitely slash the sword. To get out of this state, simply detransform.

Aside from that, MMR features an Enemizer setting. This setting is largely playable but there are some possible issues you can run into. Please refer the #known-issues channel in the MMR Discord for more information on all of this before you boot up a randomizer seed.
