There are a variety of glitches in Yume Nikki. All glitches are caused by an oversight of allowing the player to use the menu (and therefore equip effects) while seated in the chair of Madotsuki's dream room.
Speed Glitches
A useful set of glitches that increase Madotsuki's walking speed. Although Madotsuki will usually remain in her normal sprite (with some exceptions, such as when visiting FC Worlds), the glitch will be active. The bicycle is the most commonly used effect for this, as it allows for up to eight times speed.
The speed glitch will be removed if you equip any other effects. Madotsuki will sit if 1 is pressed, but the effect action will happen as well (e.g. with the bicycle, the bell noise will play). Interactions such as being unable to sleep in beds with the bicycle equipped also still occur.
Simple Speed Glitch
Instructions
- Sit in the chair in Madotsuki's dream room
- Open the menu
- Equip any effect
- Face down and press Z to exit the chair.
Speed will quadruple if the chosen effect is the bicycle, and will only double otherwise. Choosing the Severed Head effect will cause you to move at half speed (instead of the normal quarter speed).
Hyperspeed Glitch
A related glitch that is slightly more complicated, but allows the speed increase to stack, allowing for movement up to eight times faster than the walking speed. This is equal to that of Candle World's Toriningen. There are two ways of performing this glitch.
Instructions
First Way:
- Sit in the chair in Madotsuki's dream room
- Open the menu
- Equip the Bicycle effect
- Face up and press Z to start riding the chair
- Ride the chair into the Nexus
- Press 5 to drop the Bicycle effect, then pick it back up
- Open the menu (you should hear the 'unable' sound effect), and equip any effect
- Return to the dream room. There will be no chair at the desk.
- Go to the desk and sit down on the now invisible chair, then face down and press Z to get up.
Second Way:
- Sit in the chair in Madotsuki's dream room
- Open the menu
- Equip the Yuki-onna effect
- Equip the Hat and Scarf effect
- Face up and press Z to start riding the chair
- Press 1 to turn into a snowman, then press 1 again
- Open the menu (you should hear the 'unable' sound effect), and equip any effect
- Go to the desk and sit down on the now invisible chair, then face down and press Z to get up.
Speed will octuple (x8) if the chosen effect is the bicycle, and will only quadruple otherwise. Choosing the Severed Head effect will cause you to move at normal speed. Note that you can also skip choosing an effect, and apply quadruple speed to Madotsuki's normal state.
Noclip Glitch
Disables most collision, allowing Madotsuki to walk through objects and walls.
Instructions
- Sit in the chair in Madotsuki's dream room
- Equip any of the following effects: Umbrella, Knife, Nopperabou, Towel, or Cat
- Press down, then Z to get off the chair
- Quickly (while Madotsuki is still moving) press 1.
This will allow Madotsuki to walk through anything with any effect equipped. Most loading zones don't trigger, limiting the amount of areas that can be explored. Toriningen can help with accessing other areas, as they can trap you in different worlds, and their traps are easily escaped with the glitch active. Note that Toriningen can only catch you if you are on a normally solid tile, or when sharing a tile with an NPC. Otherwise, they walk through you.
Hell is useful for getting to locations with this glitch, through the use of the three Toriningen and four Nenrikido that substitute normal loading zones. The Henkei Shita located there is also the only way to get to Footprint Path A.
Getting into any of the beds in the dream world deactivates the glitch, returning Madotsuki to normal. Thus, the glitch cannot be utilized in The Staircase of Hands or its connections.
Broken Instructions
A somewhat convoluted glitch that allows you to move and enter a new area while the instructions are open, which leads to a variety of related glitches.
Instructions
- Use the simple speed glitch with the Frog effect
- Go to the area you want to do this. It has to be somewhere with a normal loading zone, where you can just walk into the new area.
- Press 1 and you should see Madotsuki sit down, then jump back up.
- Equip the Cat effect.
- Wait for a little while and the game will force you to sit down.
- Press X exactly once, a few seconds after being forced to sit down.
- Press 1, and the menu should open after the animation for the Cat effect is finished.
- Open the instructions (don't close them).
- Wait a few more seconds and then press 1.
- You should hear the sound of the Cat effect, and will be able to move freely.
- Walk into the area mentioned before.
You will now be in a glitched state where the instructions are still stored. Pressing Z when in the game world will reopen the instructions. Note that pressing Z while in the menu will not reopen it.
Sub Glitches
Invisible Madotsuki: This glitch is a side effect of broken instructions, and requires no extra setup beyond what's listed above.
BGM storage: Another side effect of broken instructions. Opening the instructions stops the music, which is set to play again after you close it. If you close the instructions in a different area, the stored music still plays instead of the area's normal track.
Glitched movement: Glitched movement is a glitch that occurs when you close the instructions while sitting down. You will be able to move and your movement will be cycling between 4 of the sitting animation sprites. Facing left will show the first sprite, and it continues in a clockwise fashion. The direction of these sprites is based on the way you face when sitting.
There is also a different type of glitched movement. Do steps 1-5 of the glitch, then press 1 to meow and stand back up. Go into any new area and you will be in the sleeping animation sprite, yet able to move freely.
Glitched movement can also be done in the real world. Wake up with the instructions stored, press 1 so you are sitting, then finally press Z to reopen the instructions. Closing it will give you glitched movement. If you save with glitched movement your save will be unplayable.
Broken witch event: If you close the stored instructions during the Witch's Flight event, the game will put you in the center of the screen and allow you to walk around and use the menu. This occurs because the game stores Madotsuki's state when you open the instructions. When the instructions are closed during the witch event, the game will put you in the same state you were in when you opened the instructions, which was the normal walking state. This glitch causes there to be two Madotsukis you control at the same time: the normal flying picture and the glitched walking player.
