Proto:Deltarune/Chapter 1 & 2 Demo (2021)

This is a sub-page of Proto:Deltarune.

To do: Add stuff in the talk page here. Patch differences. Regional differences. Also applies to subpages: Make some comparsions actually use {{compare}}. Use {{fn}} for filenames like object names; code tag for stuff like variable names.

Undertale 2 Part 2 The "Chapter 1&2" demo of Deltarune was released for Windows and Mac OS X on September 17, 2021, two days after Undertale's 6th anniversary - the date its release was announced to everyone's surprise. Being the work of a larger team compared to Chapter 1's, this demo has a wealth of unused content.

This changes Spamton's appearance depending on what action is taking place: when choosing your attack, his head grows before instantly shrinking, while making a deal with Spamton, he laughs, when choosing whether you're interested in the deal, his arms go up, and when choosing whether to give money or not, his arms go forward.

Leftover Debug Features

Credits Controls

Please elaborate. Having more detail is always a good thing. Specifically: Which patch?

During the credits at the end of Chapter 2, typing "r" on the keyboard restarts the credits. Typing "p" immediately ends the credits. This was removed by a subsequent patch.

Developer Oversights

Misplaced Spamton NEO VCR icons

Mock VCR HUD icons appear during Spamton NEO's ultimate attack on both the normal and Weird Routes. However, prior to the v1.08 update, they only appeared in the Weird Route and the battle test room without glitches; this is because the sprites are drawn relative to the room's coordinates, and the camera moves far away from the appropriate location in the normal route. This error is fixed in v1.08.

Development Text

To do: Add language file date property.

Switch Build Paths

Within the Nintendo Switch v1.03a version's options.ini are some leftover build paths.

[LLVM-Switch]
SDKDir=C:\Nintendo\sunkus-1-2-switch\NintendoSDK
UseNEX=False
nMeta=C:\Users\atrem\OneDrive\Documents\Games\Deltarune\Merged\sunkus-ch1-2-merged\DELTARUNE.yyp\options/switch/application.nmeta

Shortcut Metadata

To do: More data may exist.

In all Windows versions from itch.io, a shortcut to the executable is included, which has some leftover metadata:

Icon path	D:\builds\final_sept_16_2021\DELTARUNE Chapter 1&2 Data\DELTARUNE.exe
Machine ID	msi

The itch.io Mac 1.00 version has a GMLive executable presumably left over from development, along with a shortcut pointing to it, which also has metadata:

Local base path	C:\drune_work\sunkus-ch2-gms2.3-pc\DELTARUNE.yyp\datafiles\GMLive\gmlive-server.exe
Working directory	C:\drune_work\sunkus-ch2-gms2.3-pc\DELTARUNE.yyp\datafiles\GMLive
Icon path	C:\drune_work\icon.ico

Similar to Undertale and its demo, some audio files contain metadata. Most seem to come from FL Studio.

Unused Cutscenes

obj_example_cutscene_old

An old version of the previous unused object, which consists of Susie walking up to Kris and going back before a blank text box appears, softlocking the game.

(Source: Original TCRF research)

obj_example_cutscene_b

An alternate version of the previous unused objects that simply has the characters moving around. Unlike the previous objects, this one requires partners with you or else the game will crash.

(Source: Original TCRF research)

obj_ch2_scene26_powers_combined_old

An early version of the thrash transformation cutscene. The final object uses the Berdly statue as a placeholder sprite, while this uses the Berdly statue in a toilet sprite.

(Source: Original TCRF research)

obj_ch2_fountain_sideb

A very incomplete version of the Weird Route's Spamton NEO fight cutscene.

(Source: Original TCRF research)

Unused Objects

obj_berdlyb_tornado_old

An early version of the tornado used in the Berdly battle.

(Source: Original TCRF research)

obj_sneo_wireheart_old

An early version of Spamton NEO's heart.

(Source: Original TCRF research)

obj_sneo_wireheart_edit

Another early version of Spamton NEO's heart, which likely has its code edited from obj_sneo_wireheart_old.

(Source: Original TCRF research)

obj_sneo_heartattack_old

An even earlier version of Spamton NEO's heart, using the placeholder black and white sprites.

(Source: Original TCRF research)

obj_yheart_shot1

Old version of the projectile used for yellow heart mode. Using it will make the majority of hittable objects in Spamton NEO fight (bombs, faces, etc.) untouchable as the bullet simply pass through those.

(Source: Original TCRF research)

obj_sprite_hunter

Seems to be a cut debug tool used to find what objects use the specified sprite.

(Source: Original TCRF research)

obj_skewed_sprite_speciall

An example object used to show how sprite deformation works. Also exist another version of this that goes by the name of obj_skewed_sprite_example that doesn't deform.

(Source: Original TCRF research)

obj_queenshield_enemy_old

Two old versions of the Queen shields exists in the files. obj_queenshield_enemy_old shows shield durability with a transparent overlay in the size of the shield and breaks into pieces instead of poorly exploding.

obj_queenshield_enemy_old2 is, by default, broken, and show a single big line stretched across the screen, but with some code tinkering it's possible to get it to a more pleasing state.

Value		300	160	1000	4000
Notes		An early version of the used item Mannequin, set to be a regular item rather than a piece of armor.	Heals 100 HP when used on Kris or 90 HP when used on anyone else.	Seems to be a stronger version of the used items TensionBit and TensionGem.	Seems to be a stronger version of the used item ReviveDust, with similar character comments.

Weapons

ID		11	15
Name		TwistedSwd ツイストソード	CheerScarf チアーマフラー
Description		A strange blade おかしな剣。	A scarf with colorful you-can-do-it imagery. Gains more TP from criticals. ポジティブで前向きなイメージの カラフルなマフラ…ルダメージを受けたときに獲得するTPが増える。
Attack		+16	+1
Defense		0	0
Magic		0	+2
Ability		Trance トランス	Smiley スマイル
Value		1	250
Characters	Kris
	Susie	... uhh, looks bad. …なんだよこれ	Smiley faces? Ecch. スマイルマーク？　うぇ…
	Ralsei	It's like a spiral. ネジネジだね	You can do it! 大丈夫！　キミならできる！
	Noelle	It's... kind of scary... なんかちょっと…　怖い…	Now THIS is a tacky scarf! Faha! なにこのマフラー！　ダサーい！　ふはは！
Notes		Can be obtained by fusing a ThornRing and a PureCrystal, but the PureCrystal is unobtainable, rendering this item effectively unused as well. Uses the same ability name (Trance) as the ThornRing, but this version of Trance uses a different ability icon and doesn't appear to be functional.

Armor

ID		17	18	19
Name		DarkGoldBand ダークＧバンド	SkyMantle マウスコイン	SpikeShackle トゲの手かせ
Description		A black metal with a golden shine. 黄金色に輝く　黒い金属製。	A cape that shimmers fluorescently. Protects against Elec and Holy attacks. ぼんやり光る蛍光マント。 電属性と聖属性のこうげきを防ぐ。
Attack		0	0	+3
Defense		0	+1	+1
Magic		0	0	0
TP range		0	0	0
Ability			Elec/Holy 電/聖	Attack ATアップ
Value		200 during Chapter 1; increases in value by 420 for every subsequent Chapter	1	300
Characters	Kris
	Susie	Not even gonna ask.		Get a load of THIS! ヤベえ！　見ろよ　これ！
	Ralsei	Um, the d-dress is cute...		Looking SHARP! うーん　トガッてるー！
	Noelle	(Why did they spend $300 on this!?)		(It's tearing my sleeves...) (服のそでが破けちゃう…)
Notes		Its character comments are the same as those of the used item Mannequin, presumably as a placeholder. For some reason, they're left in English even in the Japanese strings, which do properly translate the corresponding comments for the Mannequin itself.	It's set to reduce damage from attacks with element 1 by 50%, presumably corresponding to the "Elec/Holy" elements mentioned in the description, but there are no attacks anywhere in the game that have that element set, rendering this ability useless.

Noelle's Item Dialogue

Most consumables and equipment have a set of character-specific dialogue lines for when they're used/equipped by each character. Since Noelle only joins the party for a limited time, her comments on items that can only be obtained after she leaves go unused, as do those for items that are entirely unobtainable.

Item	English	Japanese	Notes
GigaSalad	Something to graze on!	モグモグしたい！	Leftover unused item from Chapter 1. Has a healing value of 90 HP when used on Noelle, as opposed to its standard value of 4 HP.
FavSandwich	(Huh? I didn't know Kris liked this flavor.)	(クリスが　この味好きなんて…)	Leftover unused item from Chapter 1.
Ralsei Tea	There's nothing in here!	なにも入ってないよ！	Only obtainable after Noelle leaves the party. Has a healing value of 50 HP when used on her (the Tea items each have a unique healing value for all four characters).
Susie Tea	(Wonder if they sell this in gallons?)	(ボトルで売ってないのかな？)	Only obtainable after Noelle leaves the party. Has a healing value of 400 HP when used on her, the highest of all the Tea interactions.
ButJuice	B-Brainfreeze! ... kidding!	頭がキーンとする…！　…なーんてね	Only obtainable after Noelle leaves the party.
SpagettiCode	Reminds me of one of my sweaters.	わたしの持ってるセーターみたい	Only obtainable after Noelle leaves the party.
ReviveDust	What are you sprinkling?	なにを　ふりまいてるの…？	Only obtainable after Noelle leaves the party.
S.POISON	(I'll... just pretend to drink it...)	(とりあえず…　飲むフリだけ…)	Only obtainable after Noelle leaves the party. Since she doesn't actually drink it, it's coded to do nothing when used on her, as opposed to its standard effect of damaging the user for 20 HP.
EverybodyWeapon	Wh... what is this?	これって…　なに？	Leftover unused weapon from Chapter 1.
Trefoil	Okay! ...? What do you mean, unused!?	オッケー！　…え？　「ボツ」？　どういうイミ！？	Leftover unused weapon from Chapter 1. Interestingly, Noelle comments on how this item went unused.
BrokenSwd	(Wh... why give this to me?)	(え…　なんで　わたしに…？)	Only obtainable after Noelle leaves the party.
PuppetScarf	(Feels like guitar strings...)	(ギターの弦みたいな感触…)	Only obtainable after Noelle leaves the party.
MouseToken	... from the family entertainment center?	…ネズミの絵が描いてある	Leftover unused armor from Chapter 1.
TwinRibbon	... nostalgic, huh.	…なつかしいな	Only obtainable after Noelle leaves the party.

B.ShotBowtie	... do I put it in my hair?	…これは　髪につけるのかな？	Only obtainable after Noelle leaves the party.
SpikeBand	(Maybe Susie would like this look?)	(スージィに気に入ってもらえるかな？)	Only obtainable after Noelle leaves the party.
FrayedBowtie	(Reminds me of Asgore...)	(アズゴアおじさんっぽいな…)	Only obtainable after Noelle leaves the party.
Dealmaker	(Seems... familiar?)	(なんか…　見覚えが…？)	Only obtainable after Noelle leaves the party.

Key Items

ID	Name	Description	Notes
15	PureCrystal ピュアジェム	The shadow purified by the cat とあるネコの力で　闇の要素が浄化されている	Can be fused with a ThornRing to create a TwistedSwd. While the item description appears to allude to Seam's collection of the used ShadowCrystal key items, the relationship between them and the PureCrystal is not definitively known.

(Source: Zyxyz, TrainerX493, Boo (testing), Nosarms (ability icons))

Light World Equipment

As in Chapter 1, the Light World equipment can't be unequipped or examined, so the description strings for the new equipment items added in Chapter 2 cannot be seen. (Note that unlike the equipment from Chapter 1, these items don't have any use text defined.)

Item	English	Japanese
Eraser	* "Eraser" - Weapon 1 AT Pink, it bounces when thrown on the ground.	＊ 「けしごむ」 - ぶき AT1 ＊ ピンクいろ。ゆかにおちると 　 ビヨンと　はねる。
Mech. Pencil	* "Mechanical Pencil" - 1 AT * It's tempting to click it repeatedly.	＊ 「シャープペンシル」 - ぶき AT1 ＊ ついつい　なんども 　 カチカチしがち。
Wristwatch	* "Wristwatch" - Armor 1 DF * Maybe an expensive antique. * Stuck before half past noon.	＊ 「うでどけい」 - ぼうぐ DEF1 ＊ アンティークかも？　12じ30ぷんの 　 まえで　とまっている

Unused Chests

KEYGEN Chest

If a chest is placed into room_dw_mansion_east_1f_secret (the room where the KEYGEN is used to unlock the basement of Queen's mansion), it will contain a single Dark Candy. Not too useful at this stage of the game.

(Source: localwhovian, Original TCRF research)

Duplicate Revive Dust Chest

In room_dw_mansion_bridges (the first puzzle room in the Acid Tunnel of Love), the chest that's guarded by the Werewire is first set to contain a Revive Dust, before being set to instead contain... a Revive Dust.

Alternative Cutscenes

Cards

This page or section has one or more broken YouTube links. Please find an archived version of the video(s) or a suitable replacement.

In the cutscene where Lancer and Rouxls become Key Items, there is code for them to turn into cards, which is never used.

(Source: Original TCRF research)

Asset Naming Oddities

Loox Wazowski

The Loox NPC that appears in Hometown near Flower King, just like in Undertale, is referred to by the name "Mike Wazowski" internally, probably because their design bears a strong resemblance to the aforementioned Monsters Inc. character.

(Source: Original TCRF research)

Early Ambyu-Lance Name

All of the enemies that you can fight in Chapter 2 have their English name used as their internal name, except for Ambyu-Lance, who is instead referred to as "omawaroid" internally, suggesting that their name was originally "Omawaroid".

(Source: Original TCRF research)

Rurus Kaado

Similar to Ambyu-Lance, internally, Rouxls Kaard is frequently referred to as his Japanese name, "Rurus Kaado", despite the fact that the file names are in English.

(Source: Original TCRF research)

Bulking Up for Winter

Charles, the hat-wearing mouse found in QC's Diner, is internally referred to as spr_npc_most_improved_1997. In Chapter 2, he receives a new sprite, spr_npc_most_improved_1997_ch2. The only difference between the two is that the Chapter 2 sprite is one (1) pixel taller, possibly referencing his dialogue in which he says he is bulking up for winter.

(Source: u/Sympathetic_Stranger on r/Deltarune)

Not Piss

The sprite of Asgore watering the flowers is referred to as spr_asgoreu_notpiss_ch1, referencing a joke theory among fans of Undertale: that Asgore was pissing on the flowers in the garden right before he talks to you (based on the absence of a water can and the suspicious shaking he does). As stated by these filenames, he does not, in fact, use piss to water his flowers.

(Source: Original TCRF research)

DEVICE_FRIEND

The ominously grinning face with pink and yellow eyes that can be seen for a split-second in the Mansion Basement has its object name as DEVICE_FRIEND and its sprite name as IMAGE_FRIEND, which is rather concerningly suspicious given that ALL-CAPS internal names are for the most part, only used for things that take place outside the context of the game's world.

Music

BIG SHOT

BIG SHOT, the song that plays when fighting Spamton NEO, is internally referred to as spamton_neo_mix_ex_wip.ogg.

(Source: Original TCRF research)

Susie Neo

Susie's theme for the cutscene in school where Susie pushes Kris against the lockers is referred to as s_neo.ogg, while the creepy sound effect that plays as she threatens to bite Kris' face off is called s_neo_clip.ogg.

(Source: Original TCRF research)

Normal Noelle

Lost Girl, Noelle's somber theme in her room in Queen's mansion, is referred to as noelle_normal.ogg, whereas Girl Next Door, which is more commonly used as Noelle's theme, is called noelle_school.ogg, which may imply that Lost Girl was or is meant to be Noelle's 'main' theme.

(Source: Original TCRF research)

Weird Route Music Names

Unlike most Chapter 2 tracks, the music from the Alternate/Weird/Snowgrave route is not found in the official Deltarune Chapter 2 soundtrack. Internally, they're called cybercity_alt.ogg (a longer, alternate version of "WELCOME TO THE CITY" that plays in the Cyber City when you're far enough into the route), d.ogg (plays when Noelle momentarily snaps out of it and realizes she's fighting Berdly), berdly_battle_heartbeat_true.ogg (second Berdly fight theme), and flashback_excerpt.ogg (plays during the cutscene with Noelle after she leaves Rudy's hospital room).

(Source: Original TCRF research)

Muscle Sans

Just like in Undertale, Sans' theme, sans., is referred to as muscle.ogg in the game files.
