This is a sub-page of Proto:Deltarune.

This cactus is UNDER CONSTRUCTION
This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.
Hmmm...
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.

Unused Objects

obj_example_cutscene

An object that is connected to a test cutscene involving the mention of a "peepee town" and an early version of the dialog that appears after exiting the computer lab.

(Source: Original TCRF research)

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_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_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)

Unused ACTs

Spamton NEO

The code is set to react to a fifth option in Kris's ACT menu and spawn obj_sneo_throwkris_vine_controller, which begins the usual Kris throwing sequence and should spawn six obj_sneo_throwtarget objects. Unfortunately, the code is very broken and doesn't properly progress through all of the states. If fixed, it's revealed that the throw targets use otherwise-unused graphics.

While the code to trigger this is not in the final game, much like Ralsei's FluffyGuard spawns an instance of obj_sneo_tiny_ralsei there likely also existed an ACT which spawned obj_sneo_tiny_susie. If the object is spawned manually, it forms an auto-firing arrow in front of Kris's soul. The projectiles it shoots, obj_sneo_tiny_susie_axe, home into and destroy most of Spamton's attacks (though not all of them). A few attacks are also programmed to damage the arrow, and after five such hits, the arrow disintegrates.

There also exists an earlier version of obj_sneo_tiny_ralsei named obj_fluffyguard. A bubble (using spr_queen_winebubble_edit2) appears around the soul and protects it from attacks. After 10 hits from projectiles, the bubble vanishes.

Queen

There exists a case in Queen's code that would allow Susie to throw both Kris and Ralsei; the latter is thrown only if Kris hasn't already hit all of the targets. The graphics associated with this scenario are only seen here, and consequently go unused in normal gameplay.

(Source: Skawo)

Dojo Challenges

When attempting Graze Challenge 1 at the Party Dojo, it's normally impossible to ACT since the start of the player's turn is delayed by 999,999 frames (equivalent to about 9 hours and 15 minutes at 30FPS), but the enemy object used for this battle (obj_dojograzeenemy) has some basic ACT scripts with associated dialogue set up in its code anyway:

Action Text
Check
 * GRAZECHALLENGE - Graze the bullets!
S-Action
 * Susie acted!
R-Action
 * Ralsei acted!

Oddly enough, Jigsaw Joe's enemy object for his dojo challenge also has code referencing the latter two strings, despite not having S-Action or R-Action enabled as valid ACTs to use against him in his scr_monstersetup entry (meaning that they also go unused there).

(Source: Original TCRF research)

Mauswheel

Mauswheel's code contains a copy of Maus's generic N-Action script that's missing the check for whether Noelle has overcome her fear of mice and its associated dialogue for if she has. This goes unseen not only because Noelle is never available when fighting Mauswheels in the final game, but also because Mauswheel doesn't have N-Action enabled as a valid ACT to use against it in its scr_monstersetup entry.

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.

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.

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.

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.

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.

(Source: Original TCRF research)

Alternative Cutscenes

Cards

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

Sprites of Asgore watering the flowers are referred to as spr_asgoreu_notpiss_ch1_0 and spr_asgoreu_notpiss_ch1_1, 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.

(Source: Original TCRF research)

Leftover Debug Features

Hmmm...
To do:
Add actual debug features.

Credits Controls

Acactussayswhat?
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.

(Source: blaize.mayes)

Development Text

Hmmm...
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.

Shortcut Metadata

Hmmm...
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

Music/Sound Metadata

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