The SECRET 4th And 0th Day - Zelda Majora's Mask 

Ah man. I can only imagine how ominous and scary the moon would've been had it initially started that far away. You wouldn't even know it had a face! I would love the 7 day cycle, but I'm sure the N64 couldn't support such a heavily scripted week and opted for the 3 day cycle.

Link on day 1 of the 7 day cycle: i don't know why you're so worried about the moon Link on day 4 of the 7 day cycle: *squints* oh shit

5:35 “This confuses the game...” Me: This confuses ME

Being a game developer, this is my take on the size of the moon. When you model assets, they are usually a standard size in the 3d modeling software. In the game, you can easily scale these assets. I think the 'distance' of the moon when it's VERY tiny isn't a matter of distance, but rather size. Each day in the game shows the moon being closer, but I believe that it's always in the same position in the game, just scaled to different sizes. So, when you see it VERY tiny on the 4th day, it's actually the game resetting it back to the original size it was when it was imported to the game. (Just a theory)

Majora's Mask days 1 2 3 are actually Majora's Mask days 5 6 7.... That's about as confusing as Star Wars episodes.

Actually the moon ISN'T far away, it's model was shrunk. Using a hover code you can float up and see the moon is only slightly bigger than link.

4:01 genuinely scared the shit out of me

I honestly doubt that the moon would be THAT small on the first of seven. That strikes me more as an error-handling placeholder so the devs would know if they did something wrong related to that routine.

The truth about the 4th day glitch is that you pretty much loaded the map state for the ending cutscene. That explains the far away moon, the missing NPCs, and other broken stuff.

The distance of the moon resetting so far away might be cause by a "moon distance" variable that overflows when going past the intended distance. The distance of the moon isn't determined by a specific distances for each day as , if you look closely, the moon is constantly getting closer. That's just my guess though and I could be way off.

aww you forgot that you can see the wedding scene right outside clock town.

When I understood that correctly, we go outside the 3-day cycle into the 4th day, which is now the first day of a week. Playing Song of Time at an owl statue returns to Day 0 - which should be the 3rd day of the normal cycle, but is Day 0 of the normal cycle. Defeating the aliens will return from Day 0 to Day 1 of the normal cycle, wtf. Now, how can we go day -1 ? When day 1-3 are Friday to Sunday, Day 4 is literally Monday and Day 0 is Thursday. So, the moon should correspond to the missing day by it's size.

The moon is more far away than our real moon😂

0:30 that arrow on his mouth 😉

Background music literally giving me a panic attack - reminding me of how terrified i was on those final in game hours...

Integer underflow is the reason why the moon seems far on invalid days, NOT the 7 day theory.. N64 uses 16 bit registers, allowing up to 65k to be assigned as a value. If you try exceeding 65k, it'll overflow resulting in thr value wrapping around to 0. If you go below 0, it'll underflow and reset to 65k. Seeing how the moon's distance decreases relative to time, going past the 3rd day triggers an underflow (since advancing a day results in decreasing moon's distance), making the moon as far away as the hardware will allow. Next time, please get a programmer to assist.

I couldn't place your accent for a solid two minutes until I realized... you're Dutch. I'm Dutch. I feel very silly now. Great video, by the way. This was stuff I never knew about!

It’s interesting, the seven day cycle would start the moon at the real world position of the moon (very far above in the sky). I wonder if it ever came to be how quickly the moon would move.

who got jumpscared at 4:02

No, the "Fourth Day" is not the first day, it's definitely the fourth. It's not that the game has no where to put the moon, and that isn't the moon's default state. If you beat the game the moon is in that position and the end of the game is set in that fourth day.

I've been playing this game when I was a kid and I didn't know what I was doing.

My theory is that in the source code for Majora's Mask there is a sort of "time state" which has 5 states, 3 of which are used for days 1 through 3. day "0" is used for the forest segment at the beginning of the game, and day 4 is used for the ending cutscenes after the final boss. The moon cutscene which is handled by the day 4 increment is cancelled by the observatory, which allows you to wander around in an unintended day 4 state when its only meant to be used by either the moon ending sequence or credits. Essentially, there's probably some code that goes like this: In the stuff that handles the transition to the next day, switch(getCurrentDay()) (...) case 4: if this was reached via credits then handle credits. else do moon crash sequence. default: break; However, the telescope programming probably skips various callbacks when advancing from and to it, enabling you to skip this next day check. If they wanted any extra days, it would have been implemented in said switch as long as they set the right event callbacks and such. Your days 5 6 and 7 are handled by a "default" in said switch, which is why it falls through to default moon positions and NPC states.

@5:50 ...unless rather than defining a set position for each day, the game just uses an equation to set the Z value (altitude) of the moon based on the current day.

I wish you guys would do a video with all the things you can do with this glitch. It's always interesting to see what beta content you can discover with things like this.

5:35 "This confuses the game" This confuses me. :p

this is just an opinion of mine but I don't believe the day state changes you refer to in the video are correct. Majoras mask runs similarly to ocarina of time when it comes to loading maps except for one thing. To downsize the game I believe they used a system that renders the map for the specific day so the game can figure out what NPCs and assets to load for that particular number day. the system is very similar to ocarina of time since their are day and night cycles but state changes are triggered by reloading map data. (hence why there's loading zone triggers whenever you go into a new area/new day) I could be wrong but it's just a thought.

One glitch I miss in the 3DS version is the Fierce Deity Link one. I appreciate being able to play as FD Link in the fishing hole, but that is just to fulfil a side quest.

sorry but there's a lot of plain wrong info in this video... it seemed like you guys were just kinda guessing how it worked, but presented it as fact

Wow I've never heard of the 0th day glitch. Thanks ^_^

Me in 1999: I have all 3 major strategy guides, I know EVERYTHING about this game. RU-vid >2010's: Really now... ::discreetly kicks stack of guides under my bed::

I think the moon just starts moving on day 0. Programmers start counting from zero. As for the moon being where it is on day four it could be that since there is no programmed position after day three the moon just spawns at the games 0,0,0 coordinate (or whatever coordinate Nintendo's tools put objects that don't have a properly defined position).

wouldn't the 0th day be when nothing even existed? *T H E O R Y*

A Majoras Mask remake with 7 days would be amazing!

I remember doing the 4th day glitch many years ago using cheat codes. Using L to levitate, I flew up to the moon and saw that it was really really tiny, so I assumed it was a glitched state, but after seeing this, the idea of it being the REAL first day makes more sense and sounds AWESOME! I kinda wish they could have made it 7 days just to see that, but I also love 3 days.

Fantastic video. I knew about the 4th day (not the 0th) glitch but had no idea it actually implies leftover coding from an original 7-day model.

I would have loved to see a full 7 days, but i can understand why it was cut given the really short development time.

I knew there is a 4th day (New Day) glitch, which I never could pull off, but I didn't know it was meant for the original week-long time limit that was cut.

This is too much for my brain :(

i rented one majoras when this game was "new", and one profile had 4 days naturally, i never found anything about this, but now you explained how to create this, but is not the same, that profile had 4 days as the normal of the game, what the fuck that guy made, i not know, it still a mistery for me

when that voice showed up in the video I knew who it was

I knew about the 4th day but not the 0th day, and I think you might be onto something with the 7 day theory and here's why. If you look at the moom on the first and second days, you'll notice (obviously) that it gets much bigger, but that literally happens in an instant. Go to the telescope room and use it to watch the moon, this way you can skip the cutscene for Day 2. The moon will instantly get oh I don't know like 40% bigger or something just instantaneously. This however does NOT happen on the transition to Day 3, it's obvious that the moon is falling but it doesn't just jump to a new size. So perhaps maybe there was a day removed between Days 1 and 2?

This video fundamentally doesn't understand how programming works. The moon's distance will just be some vector that's a function of the ingame time. That's like one line of easy code, that doesn't mean these other days were designed to have certain size moons.

too bad you didn't get to explore ruins and destroy buildings on 4th day.

2:09 - ohmigosh i want a remake with seven days pleassseeee

What if Termina exists in a plane beyond our comprehension where the entire universe exists in only three days and keeps repeating after different cataclysms?

I wana see a 3rd game. Majoras mask was soooo good aunt Diane. What a journey.

I love how Link is like "SAY WHAT?!" in the thumbnail.

Why are your file names.... Hubris? 3:26

Well I'll be damned Looks like my Saturday just got filled up After all.

the position of the moon could be based directly on the day rather than set individually for each day.

2:14 *lips smack * “while this may make sense”

1:58 Well technically, nah.

I think 7 days would have been much easier, obviously. But would it be as much fun with that much time? I think only if they had more tasks added.

If u use a hover code to get to the moon you see that the model is shrinked

Could one of these be the state the game is in during the prologue (before leaving the Clock Tower for the first time)?

Maybe the vertical position of the moon is mathematical.

what i think is that you beat the game but it regesters as the 0th day but that means the moon grows back.

So has anyone had the patience to see if the moon slowly gets closer each day to prove the existence of the 7 day cycle? I'm guessing the programming was probably not there anymore, but would be interesting to see the results.

This is not glitch. This is in game mode, you can also find it on hidden message on masked statue.

I love how the sun peeked out to see if it's ok to come out

That's creepy af, how the Happy Mask Salesman just says "only"

What if the reason the platform isnt there is because the game uses the 1-3 day cycle to know which one to put up?

The person Atreus is holding in the mural isn't Kratos.. but Odin. Black spot on Eye area and green tunic suggest that.

So if we are thinking about the 7-day cycle originally planned, then Day 1, Day 2, and Day 3 are Day "5", Day "6" and Day "7", the 4th Day Glitch allows access to Day "1", and the 0th Day Glitch allows access to Day "4"? That sure got confusing ('though intriguing) in a hurry.

Hey is this dr wily?

Real ones know this game is haunted

damn i was hoping you'd cover goron missle

You also forgot to add on the 4th day glitch if you go back to where the happy mask salesman as if you go all the way down the stairs that green door is open you could actually walk through the door that's inside the clock tower and u can walk through that spiral corridor

Actually the game was programmed with seven days. But that idea was scraped because of time restrains and the lead developer didn't want the player to be overloaded with side quest. The code is still there though so you can use an emulator or game shark to explore all 7 days if you change the value marker on the code. xxxxxxxx ???? ^these first 8 are the memory address. Change that and you won't have the code your looking for. The last two of the last four are what you need to change. They change what that code does so 00 is off, 01=day 1, 02= day 2, and so on. Once you get past 7 things get weird and you run the risk of crashing the game. Have fun.

I would be careful doing the 4th day glitch as there is a small chance it could permanently corrupt your save and force you to start completely over. That's what happened to me.

They should make a new version of the game with the 7 day cycle included.

What if someone made a Majora's Mask hack where it brought back the 7 day cycle? I'd love that.

I played the HELL out of this game and never new about these glitches! That is freakin cool!

So if I do the 4ht day glitch, I have 7 days left before the moon crashes again?

I am pretty sure the tint Moon is just an overflow and has nothing to do with pre planned days that didn't made it into the game

Actually, the end of the 4th day = the begin of the 7th day (in game time) and the days we played 1,2,3 actually are the last days from moon life cycle which are days 5,6,7..just think about it.

The 7 day cycle fits the Christ theme in this game even better. In the Bible, God made the world in 7 days and so we had a 7 day repeating cycle with the last day being Saturday, the day God rested (the Sabbath day). Then Christ comes and the story of creation continues. Jesus is resurrected the morning after Saturday, on "a new day" that was called "the 8th day" by early Christians, transcending the 7 day week. This is why Christians have church and their day of rest on Sunday instead of Saturday. Sunday is both the first day and the eighth day.

I have a theory what if it is pugatotry. Think about it when the moon crashes every one died if you ignore the guards and children and your the only one there to relive the moon crashing

I GOT JUMP SCARED WHEN THE MOON APPEARED AT AROUND 4:00, as in fourth day, as in the unused day..........DONT PLAY THIS GAME AROUND 10:00 - 5:00, the moon will give u nightmares, because its a moon............. Ill leave now.

7 days? Only helps the theory that Majora is a she.

Ah, watching gameplay of old Zelda games is so nostalgic.

Must've done a lot of research- I like all these old games with their glitches and loopholes.

Imagine how cool the game would be with 7 days because at that they could add way longeer and better dungeons along with more dungeons and the game could have longer side quest and more things packed into it if this was the case and i kina wish it was.

1:11 imagine that crashing into the town

I really wish I knew about this back when I played Majoras Mask.

whenever i try this glitch it just takes me right to the moon rashing,when i tried the 4th day glitch

there actually was supposed to be 7 days back when Majora's Mask was being developed for the 64 expansion

Very interesting I was curious too

I had founded a cheat for Majora's Mask 3D. The 4th day. The most NPCs are gone and I only founded the monsters and Bosses. The moon is completely gone or invincible. It was fun but, you have nothing to do.

This guy sounds an awful lot like Dr. Wily...

Ima use this glitch in real life for any occasions of some random thing coming down to hit

Since, from Bakugo's logic, a deku is someone who could never be a hero, I would like Katsuki to play majoras mask, or watch kirishima play it, almost entirely as deku link.

You sound exactly like Dr Wily 🤔

they should of made a master quest where Nintendo actually make a 7 day majora mask game work (so we can experience the updated majora mask experience with better graphics and a whole new experience)

O n l y . . . [Game crash] That's some creepy pasta shit!

I accidentally did a glitch once and haven't been able to replicate it in Majora's Mask. As a kid, I had the Legend of Zelda: Collector's Edition and loved MM. I was in the Snowdin Mountain and was terrible at using the Goron mask, ran into a corner, and fell through the corner. I could walk around and look up at the room, but it was all red. I could hear the lava sound so I just turned into a deku to restart the room.

Damn Majora's mask should have a remake where there's seven days and a bigger adventure and in 3D lol

So the moon moves 6 or 7 times getting closer and closer? When it's way out there that's it's first position and on the 7th day it's closer

lol this whole video can be explained by the fact that when you exceed a parameter in games lets say 99/99 if you get 100/99 the computer doesn't read it as extra it reads that extra decimal as a negative sign so the moon is really far away because it is set to negative 99 same for the building and why the mask salesman tells you the time in letters

The guy talking at first sounds like a nerdy norwegian student trying to speak english and overcompensating like hell
