This is a sub-page of Proto:Yume Nikki/Version 0.04.

Unused Graphics

These graphics are exclusive to v0.04, or were first found in this version.


Found in the CharSet folder are the two bed sprites. In v0.04, the bed sprites that are used are only in ChipSet images. It's worth noting that this image matches up perfectly with the beds on the ChipSet for Madotsuki's room, 部屋チップ1.png.

Yn004 CharSetBeds.png


Some stone blocks can be found in Puddle World's ChipSet, but they are not used anywhere.

Yn004-06 PuddleWorldBlocks.png


Found in the ChipSet folder is a loose image of the tiles used for the dirt in the Barracks Settlement. It's most likely a leftover from before Kikiyama pasted the tiles into the respective ChipSet.

A similar image for The Wilderness tiles can be found in the Thumbs.db images with the same 64x32 dimensions under the name 砂浜64 32.png.

Yn004 Dirt.png


The elevator graphics used for the Mall in v0.10 exist in v0.04, but are never utilized. They are colored differently from its v0.10 counterpart.

v0.04/v0.06 v0.07 onward

Forest World Ghost

The face of one of the ghosts found in Forest World, specifically the one with the pink mouth. The center of its mouth is darker, making it look like it has lips. This tile was removed by v0.06.

Unused Used

Hat and Scarf Effect

An alternate version of the Hat and Scarf effect where Madotsuki's braids are hidden. It was overwritten by Mafurako's visible form in v0.08.

Unused Used
Yn004-UnusedHatScarfEffect.png Yn-MadotsukiHatScarfEffect.png


A light graphic broken up into three rays. The shape suggests that it could have been used to show the shine on windows.

Yn004 UnusedLight.png

Sordid ChipSet

An image named どろどろ.png ("Sordid" or "Muddy") can be found in the ChipSet folder. It is not assigned to any tileset in RPG Maker 2003, and was deleted by v0.06.

It contains some reddish terrain, several poles, and the blood splatter that's found in other maps. The two typical gates are also present, showing that the map that would have used this ChipSet would have had connections to other worlds.

A mock-up map of how this ChipSet could have been used has been provided.

Yn004_MuddyChipSet.png A mock-up of how this ChipSet could be used.

If this ChipSet is added into RPG Maker 2003, the red terrain is revealed to be an animated water tile.

Yn004 MuddyWaterTile.gif

Submarine Fish

Both the used and unused variants of the Submarine Fish from v0.10 have sprites in v0.04, but neither of them are used. Both of them lack shadows in v0.04, having a "chopped-off" appearance.

v0.04 - v0.07 v0.08 onward
Yn006 SubmarineFish.png Yn010 SubmarineFish.png


What appears to be an earlier version of the TV can be found on the same CharSet image as the TV that is used, along with an unfinished outline of the TV.

Vending Machine

Just an ordinary vending machine, except in the CharSet folder. The vending machine sprite that is used is on ChipSets instead, however, none of them have the teal background found in this image.



The Will-o'-the-Wisp effect only has a mugshot in each of the other versions that have been found, but v0.04 finally allows us to see the sprites that would have been used with this effect. It appears that it would have been able to change colors.


Thumbs.db Images

Version 0.04 has a lot of hidden images within its Thumbs.db files, offering a look at in-development graphics and ideas Kikiyama had for the game. Sadly, the quality of these images are very poor due to the nature of compression in Thumbs.db files.

Some of the timestamps on these images are from before v0.00 was released, with a few dating back all the way to early 2003.

Thumbs.db Image Used Image (If available) Japanese Filename Translated Filename Folder Location Date Modified Notes

Yn004-DarkSeamountThumb.png N/A 海山暗.png Dark Seamount Panorama 6/14/2004 (09:44:52 UTC) The name implies that it should be dark, but it appears very bright instead, like it was altered with an emboss effect.

  • While intended for a world with a black background, it's unclear which one it would specifically belong to.
Yn004-BackgroundCharacter6Thumb.png N/A 背景キャラ6.png Background Character6 Panorama 6/2/2004 (06:29:52 UTC) The other 背景キャラ image that is skipped over.

  • The title of the game within the image translates to Severed Head PK.
Yn004-SeveredHeadSCMainThumb.png N/A 生首SCメイン.png Severed Head SC Main Picture 9/7/2004 (14:32:32 UTC) The playfield for the scrapped minigame.

Yn004-SeveredHeadSCHeadSelectThumb.png N/A 生首SC首セレクト.png Severed Head SC Head Select Picture 9/7/2004 (14:30:08 UTC) Apparently the scrapped minigame would have had a player select screen.
  • The text below probably says ナマクビ ("Severed Head" in Katakana).
Yn004-BrightLampThumb.png N/A 電燈明.png Bright Lamp Picture 7/27/2004 (04:20:12 UTC) A tiny image of a lamp turned on.
Yn004-DarkLampThumb.png N/A 電燈暗.png Dark Lamp Picture 7/27/2004 (04:21:08 UTC) A tiny image of a lamp turned off.
Yn004-MySystem2Thumb.png Yn004-MySystemASystem.png マイシステム2.png MySystem2 System 1/30/2003 (08:58:34 UTC) Looks like an alternate version of a menu scheme you can receive from the Toriningen in the Mall.
Yn004-MySytemTransparentThumb.png N/A マイシステム透明.png MySytemTransparent System 6/2/2004 (05:39:24 UTC) A transparent menu scheme.

Shared with v0.10

These graphics are also still unused in v0.10, showing that Kikiyama was holding onto some assets from 2004 for possible future use.



The same sprites for the unused Blindfold effect are still here. The only differences are that the mugshot has a bluish background, and there are no wake-up sprites.

Yn004 Blindfold.png

Chair-Riding Madotsuki

A mugshot for when Madotsuki is riding the desk chair exists, but can never be seen in-game. The scooting animation for sitting still in the chair is also unused in this version.

Yn004 Chair-RidingMadotsuki.png Yn-UnusedChairAnimation.gif

FC World Crick in the Neck

FC World sprites for when Madotsuki has this condition exist, like in v0.10, but are never used.


Greyscale Madotsuki

While some sprites of Greyscale Madotsuki are used in Mini Hell, the walking sprites and mugshot are never seen in-game, just like v0.10. Like all mugshots in v0.04, it has a bluish background instead of a black one.

Yn004 GreyscaleMugshot.png Yn GreyscaleMadotsuki.png

Will-o'-the-Wisp Mugshot

The only remnant of the Will-o'-the-Wisp effect in later versions. Like all mugshots in v0.04, the background is blue instead of black.

Yn004 WillOWispMugshot.png

CharSet Graphics

FC World Square

A 16x16 square found in an FC World CharSet. It was probably used to measure FC World sprites.



The same unused colorations of Kinoko-san are also found in v0.04.

Yn unusedKinoko.png

Madotsuki's Room & Effect Objects

The same unused objects and tiles for Madotsuki's room are also present in v0.04. Some of them are alternate designs for objects that you collect effects from.

Yn-madotsukisroom.PNG Yn-trash.png Yn MadotsukiRoomObjects.png Yn-unusedthing.png

The Mall

The friendly toriningen in the Mall has sprites for facing other directions, but it only ever faces forward.


Eye Palm

The Eye Palm has graphics for facing left like the other arms, but this is never seen in-game. These frames remain in v0.10, but are still unused.


ChipSet Graphics

Barracks Settlement

Yn-BarracksSettlementJellyStalk.png Yn-BarracksSettlementSmallJellyStalk.png

Two types of jelly stalks are never used.


Some confetti can be found in Forest World's and Shield-Folk World's ChipSets. It still isn't used in later versions.


Dotted Tiles


These tiles have a similar pattern to the floor tiles used in Hell, possibly making them in-progress versions of the tiles.

FC World

Yn-FCGoblinTile1.png Yn-FCGoblinTile2.png

There are some additional tiles for the FC Goblin room, suggesting that the room could have had a different layout at some point.

Madotsuki's Room

YumeNikki-cracked-window.png Yn windowReflection.png Yn MadotsukiRoomAutoTile.png Yn-MadotsukiRoomUnusedFloorTiles.png Yn-MadotsukiRoomUnusedWallTiles.png



Some kind of hole that is never used in the Mall.


This autotile is a recolor of what's used in Madotsuki's room, but is never seen in the Mall.

Puddle World

Yn-PuddleWorldTiles1.png Yn-PuddleWorldTiles2.png Yn-PuddleWorldTiles3.png Yn-PuddleWorldTiles4.png

These tiles are likely placeholders. The circular tiles can be used to (kind of) make your own custom puddles.

Sewers Graffiti

The unused sewers graffiti is also in v0.04.

Yn SewersGraffiti.png

Windmill World


Some tiles that resemble tatami, a type of Japanese flooring.
