Yume Nikki ("Dream Diary") is the story of a young girl named Madotsuki who has very strange dreams. The game is a wide-open world, with no main goal besides collecting all the effects.

To do: More unused graphics on this document.

Sub Pages

Unused CharSet Graphics Object and character tiles leftover from older versions, or completely unused.

Unused ChipSet Graphics Map tiles that are never utilized.

Default Assets

All the default graphics, sounds, and music assets from RPG Maker 2003 remain in the game's files, unused.

Unused Effect Sprites

There are some sprites for more effects in the game, as well as additional sprites for some existing effects.

Blindfold

This unused effect has Madotsuki wear a blindfold. The 8-bit wake-up pinch sprites are overwritten by the Triangle Kerchief effect when invisibility is active.

Chair

A mugshot exists for when Madotsuki is riding the desk chair, but even with the various chair-related glitches, it can never be seen. Perhaps at one point, being able to open the menu while seated in the chair was intentional, and not a bug.

Crick in the Neck

This isn't really an effect; it's a random condition that may happen when you get out of your bed. All you're able to do when you have it is sit down and go back to bed. If you go back to bed, when you wake up again you're back to normal. But...

There are 8-bit sprites for it! This indicates it may have been an effect at some point.

Greyscale

In the mini-Hell accessible from the Number World, there's a ghost of you that's always facing you. It looks the same as you, but grey and transparent. Just an NPC, right?

Nope, this mugshot indicates there was supposed to be a Greyscale effect at some point, or that you would become grey when in the White Desert. The fact there's no 8-bit version of this effect supports that theory. The walking sprites are also unused.

Stoplight

There are graphics for an unused state of the Stoplight effect with both lights off. FC World sprites also exist for this state.

Will-o'-the-Wisp

This unused effect met with the same fate as the Blindfold effect. The mugshot for it is found in version 0.10 and 0.06, but the actual sprites of it have only been found in version 0.04, although they are not used anywhere in the actual game. The triangle on it suggests it was what originally happened when using the Triangle Kerchief effect.

Witch

Duplicates of the Witch effect sprites without shadows exist, but are never used. They were probably intended for flying over an area with no visible ground, or for the Witch's Flight event, which ended up using pictures instead.

Unused Areas

FC World C

This unused right half of the map, dubbed FC World C by fans, is inaccessible by normal means. No events are scripted in the area.

FC World Peninsula

Map0153 is an unused FC World map with a hand motif on the ground and a few statues. No events are programmed in this map, so you cannot exit. It resembles the initial locations in FC World A and B that you are teleported to from the Teleport Maze and the Barracks Settlement, respectively.

Unused Panoramas

Neon World

The only unused background in the game, internally known as ネオン背景.xyz. Curiously, with the debug party member (see below) equipped, this background appears in Neon World, although it is not symmetrical and therefore does not look as intended.

Unused Pictures

3-Line Message Window

A message window that allows three lines of text. There is never an opportunity to use this window in 0.10, but it might have been used in version 0.05, the first version to add borders for messages.

Unused Audio

Plop

A plop sound can be found in the Sound folder under the name ピコッ.WAV. This is a leftover from version 0.04, where it was used when you received juice from the vending machines.

Unused Sound Triggers

This sound plays if you noclip to interact with the creature that rarely appears in the pond on the Witch's Island. It is used for when you stab the big Goblin,, and sped-up when interacting with an NPC in the Neon World, although it is missing from some English versions.

Debug Functions

Debug Room

Download Madotsuki's Room - Debug Room Warp File: Yume nikki debug room.rar (3 KB) (info)

The Debug Room is accessible through two methods: rename the file Map0001.lmu to the name of another map, such as Map0003.lmu (Madotsuki's room in the real world), or set an event that goes to the debug room in RPG Maker 2003.

The various objects in the room all do different things:

• The Mirror gives you the Fat effect. The mirror was used in older versions of Yume Nikki for obtaining this effect. Garbage text may display if playing the English version due to the string being untranslated. Under normal circumstances, it should show up as "★ふとる★".
• The Neon Creature plays a sound effect and stops the music, if any is playing. It acts like a typical NPC in game, reacting as you would expect from the Cat, Knife, and Stoplight effects.
• The FC World equivalent to Witch Madotsuki plays the 8-bit version of the effect sound.
• Nekoin (the cat coin) gives you all of the effects and warps you to White Desert B. If you already have the effects, you will get duplicates.
• Flying 8-bit Witch Madotsuki starts the Witch's Flight event, but you can't move.
• The chair in the top right corner lets you save, but you won't be able to get out of the chair. Sometimes, the Witch's Flight event plays at the same time.
• Going directly to the left of the traffic cone warps you to Mars-san, but you are put in a place where you cannot move. Waking up is possible if you were already in the dreamworld prior to entering the debug room.

Debug Party Member

Another party member can be added to your party, but this never happens in-game. It's nameless and there are no sprites associated with it, but having it in your party causes several scripts in the game to change:

• All sane and insane Toriningen disappear. The Toriningen Party and the nice lunatic in The Mall are not removed.
• The top-left cupboard in the Guillotine Room will disappear. If you stand on its former tile and press the action button, you'll end up in front of one of the eight cupboards in Number World. If you enter the world again, the cupboard will have returned to its rightful spot. This works in the bigger version of the Guillotine Room, too.
• If you wake up, you will be unable to move. You can still open your menu.
• In the Neon World, an unused background scrolls by (mentioned above).

Test Play Mode

When running the game through RPG Maker 2003, various debugging tools are usable during gameplay. These can also be enabled by creating a shortcut to RPG_RT.exe in the game's folder, and appending TestPlay to the end of the command.

• Holding the CTRL key while moving will allow no-clipping.
• Pressing the F9 key will bring up a menu where you can toggle switches and modify variables.

Revisional Differences

Years after version 0.10's release, publishing rights to Yume Nikki were acquired by AGM PLAYISM, providing new distribution platforms for the game. The versions distributed by Playism have minor differences from the original 0.10.

Yumesyussei Patch

An optional patch on Kikiyama's site titled Yumesyuusei is available to update version 0.10 to fix some bugs present in the initial release.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Determine the locations of the bugs that haven't been added to the bugs page

The changelog, while speaking in mostly general terms, states that the following issues were fixed:

Japanese	Translated
特定のマップにてリンクミスがあり、場所移動しようとするとエラーが発生してしまいます。	There was a link mistake in a particular map, and an error occurred when moving to a location.
特定のマップにて本来通行できない部分を通行できてしまい、そのまま進めていると操作不能になることがあります。	It was possible to go through a part in a specific map that is not supposed to be normally passable, causing it to become inoperable if proceeding as is.
お金の「円」表記が「G」になってしまっています。	Currency was displayed as "G" instead of "円" (Yen).
扉部屋以外のところでテンキー５が効いてしまい、エラーが発生することがあります。	Number key 5 worked in places other than the Door Room, potentially causing errors.
椅子の上でテンキー１が効いてしまいます。	Number key 1 could be used in the chairs.
ミニゲームのボーナスが特定の条件で入らないことがあります。	The minigame bonus could not be entered under certain conditions.
特殊な起床の後、座り込み動作が挟まることで主人公が透明化したり、セーブ時に操作不能になることがあります。 ※こちらに関しては、操作不能状態になったセーブデータで開始しても正常に復帰するように修正を行いました。	After a special wake-up event, the protagonist may become transparent due to the sit-down action being caught, or become inoperable at the time of saving. For this, it was corrected so that operation will return to normal even if the loaded data had the issue.
新規マップにて画面半分が真っ黒になって表示されることがあります。	On the new map, half of the screen may appear black.
特定のマップにて箒で浮いても足音が鳴ってしまいます。	The footstep sound is heard even if you float with a broom on a certain map.
特定の場所でエフェクトを使用して扉の部屋に戻ると、スクロールが固定されたままになってしまいます。	When you return to the Door Room using an effect in a specific place, the scrolling will remain fixed.
特定のマップにてマップチップの表示優先順位がおかしくなっているところがあります。	In a certain map, there are places where the display priority of map chips is incorrect.
その他、若干の調整を行った部分があります。	Other adjustments have also been made.

Peruse the bugs page for explanations on these issues.

All future releases of Yume Nikki would be based on version 0.10 with this patch applied, including the fan translations and distributions from Playism. Kikiyama did build a version titled 0.10a that has the Yumesyuusei patch pre-applied, but the download link on their website was never replaced to host 0.10a, leaving its distribution to Playism.

Playism Release

Yume Nikki was added to the Playism distribution platform in Japan on February 12, 2012, followed by an official English localization releasing worldwide on July 13, 2012.

These versions are based on version 0.10a, which is 0.10 pre-applied with Kikiyama's Yumesyuusei patch available on their homepage. Manually applying this patch to the original 0.10 does not add 0.10a to the title screen, though the changelogs included with the Playism releases reveal that Kikiyama built a version that shows 0.10a on the title screen on October 6, 2007.

0.10	0.10a

Playism's English localization notably mistranslated some of the effect names, rendering the Severed Head effect as Talking Head, and the Demon / Oni effect as Devil.

Steam version

Yume Nikki debuted on Steam on January 10, 2018, in an effort to help promote the then-upcoming reboot, YUMENIKKI -DREAM DIARY-. It is offered in both Japanese and English, with the former being identical to the previous Playism release.

The initial English version featured on Steam contained the same localization as the Playism release, but suffered from numerous bugs that resulted from renaming the game's files to allow Yume Nikki to function properly without a Japanese system locale. These bugs primarily consisted of crashes from not being able to find a specific file, sounds not playing, sounds not playing at the correct tempo or volume, and tilesets appearing when viewing the menu in FC World with certain effects equipped.

Oddly, the initial release had a second copy of the game contained inside a folder titled DreamDialy. The only difference between this and the the main folder is that DreamDialy was built with an older version of RPG Maker 2003 that lacks the new features offered by the version on Steam, such as options for window scaling.

The RPG Maker 2003 splash screen upon starting up the game differs depending on the version being played. The original Enterbrain splash screen is shown in all versions (including DreamDialy) except the English Steam version, where the Kadokawa splash screen is shown instead.

Enterbrain	Kadokawa
