Chapter 1 & 2 Demo (2021)

This is a sub-page of Proto:Deltarune.

Notes

Differences from the Final Version#

To do: There's more stuff that should go in here

• The game_change() function that was added to GameMaker specifically for Deltarune is not used or indeed supported at all in this version.
  • Chapter 1 and 2 were seemingly still developed as separate projects internally, but were merged together before release, with leftover development text alluding to this.
  • The assets for the two chapters are still effectively separate (and in many cases duplicated) similar to the final game, but they are all located in a single data file, with Chapter 1 assets being suffixed with _ch1 to separate them.
• Swatch has a different overworld sprite, closer to his original concept art. This was changed in the 2024 LTS demo and final game to more closely match his shop appearance.

Early	Final

• Save files still store raw GameMaker room IDs, but because the chapters are merged, all of Chapter 1's rooms had their IDs shifted up to start at 281 (280 before version 1.08). Saves with the old IDs can be loaded and will automatically convert, but new Chapter 1 saves made in this demo will have the higher IDs, making them incompatible with the original 2018 demo.
  • This caused a problem when version 1.08 of the demo added an extra room, requiring hacks to be added to work around it, which was likely the reason for room IDs being explicitly defined in code in the final game.
  • Saves made in the full version are incompatible with both demos due to the absence of said room ID list.
• Dogcheck also still operates on room ID ranges:
  • For Chapter 1, only rooms from 282-411 (281-410 before 1.08) are considered valid, which is the same as the original Chapter 1 demo just with the higher IDs.
  • For Chapter 2, only rooms 12-232 and room 4 (11-231 and 3 before 1.08) are considered valid, compared to the final version where every room in the chapter is a valid save room.

Unused Graphics#

Susie's Room in Queen's Mansion#

A sprite version of Susie's room in Queen's mansion under the name spr_dw_mansion_room_susie_example that was removed in one of the updates. Completely identical to the used room aside from the faster-moving character mess.

Unused Audio#

audio_menu.ogg#

An unused song only included in the itch.io Mac 1.00 version, that uses "Faint Courage"'s leitmotif. According to the file name, this track seems to be used in the Chapter 2 menu screen at one point. The final game uses an entirely different song, "Faint Glow", as the menu theme (prior to completing Chapter 2, after which "Before the Story" plays).

The file name may be supposed to be fully in uppercase like other audio files with an AUDIO_ prefix, but Mac versions of the game have all files converted to lowercase, leaving it unclear.

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:

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:

Debug Mode#

To do: Add actual debug features. Note which of these still work after v1.08.

Similar to the Chapter 1 Demo, this demo features a debug mode that was stripped from the final release.

Print Messages#

Most of these were unfortunately stripped out starting from v1.08.

Ambyu-lance Battle#

Berdly Battle#

Tasque Manager Battle#

Spamton Battle#

Rouxls Kaard Battle#

Other#

Object Debug Menu#

Pressing down on the scroll wheel on your mouse will open up an object debug menu. Here you can move objects, see their info, and edit their properties.

Pressing the Page Down key will show general info about every object on screen, including their names, positions and hitboxes, as well as your cursors position. Pressing Page Up changes how the object positions are showed, either being their base position, position relative to the camera, or position relative to where they spawned.

You can select any object using left click, and then you can drag it wherever you want. When an object is selected, you can right click to open up an options menu where you can change its sprite, change a number or string variable, watch a variable, or delete the object. You can also use the arrow keys to move it precisely. Right clicking without an object select brings up a menu where you can set or watch a flag, set or check a global variable, select a specific object, or create an object.

This menu is a bit buggy when used in the Light World, as the mouse created when right clicking isn't accustomed to the Light World's lower internal resolution and can barely reach outside the upper left quarter of the screen. The menu created by right clicking also spawns in the wrong locations for the same reason.

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.

Chapter 1 Changes#

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Investigate the files suffixed with _ch1 (but not _ch2).

With the almost 3 year gap between Deltarune Chapter 1 (aka SURVEY_PROGRAM) and Deltarune Chapter 1&2, it's only natural that Chapter 1 would've seen a few minor tweaks and fixes along the way.

Noelle#

Noelle's side profile was changed significantly with the release of Chapter 2, adding her tail, shortening the length of her teeth, and... well, unflattening her. 2 additional frames were also added to her walk cycle. Her talk sprites were also updated.

SURVEY_PROGRAM
Deltarune Chapter 1&2 Demo

Librarby#

Language	SURVEY_PROGRAM	Deltarune Chapter 1&2
English
Japanese

In the original Chapter 1 demo, the door to the computer room in the Librarby was a single door located slightly to the left. Since this is the entrance to the Cyber World in Chapter 2, the cutscene of Kris and Susie entering it would probably look a little awkward with the original design, so it was changed to a centered double door in the Chapter 1&2 demo, though the right side of the door mistakenly lacks hinges. The computer room sign had to be moved to the opposite side of the door and shrunk as a result of this. Of course, Chapter 1 in the Chapter 1&2 demo reflects this change as well.

SURVEY_PROGRAM	Deltarune Chapter 1&2

Additionally, the original version had some stray pixels on the second layer that were removed in the 2021 demo.

Wrist Protector#

SURVEY_PROGRAM	Deltarune Chapter 1&2

If a Chapter 1 save file is created with the 2021 version, the Wrist Protector from the original version (obtained by reaching the Dark World in under six minutes) can no longer be found and its functionality will be enabled by default, even before going to the Dark World.

Changed Text#

There's also a bunch of non-notable control character changes.

Revision Differences#

To do: Cover older versions. Here's a code comparison between versions for reference; HgPatcher can also help. See also Deltarune Wiki. Confirm the info for the following versions: 1.08, 1.09 and 1.10.

Version 1.000#

Launch version of the demo.

Version 1.002#

Added a question mark icon for unknown controller inputs.

Version 1.003#

Released on September 18, 2021. Mainly fixed crashes related to controller configuration.

Version 1.004#

Released on September 19, 2021.

• Fixes a softlock that occurs when standing in Noelle's way as she jumps back from the other side of the laser wall in the "DECEMBER" room.
• Fixes a softlock that occurs when sparing Poppups while other party members are performing an ACT.
• Fixes a crash that occurs after helping a Swatchling and breaking a vase in the Acid River.
• Fixes a crash that occurs when performing the "Block" ACT on Poppups with frame-perfect precision.
• Fixes a crash that occurs when pressing the spacebar in two rooms in Queen's mansion.
• Fixes a crash that occurs when pressing up while inserting the LoadedDisk into the NEO robot in the mansion basement.
• Fixes a crash that occurs when checking the Recruits menu at a save point at the end of the game when only some enemies have been recruited.

Version 1.0.5#

Released on September 21, 2021.

• The player is allowed to quit after losing to Giga Queen, instead of being forced to restart the fight.
• Losing to Queen and Berdly has the player respawn closer to her room with the party's HP restored.
• Losing to the teacup ride in the mansion basement respawns Kris in the same room instead of forcing them to restart from the beginning of the area.
• Losing to Spamton NEO respawns Kris just before inserting the LoadedDisk, so that the player can backtrack.
• Fixes an error in which the three damage numbers at the end of Spamton NEO's fight in the Weird Route improperly display as blue (Kris' color); they now properly display as yellow (Noelle's color).
• Unspecified additional bugfixes.

* (Dodge Queen's attacks with left, right, and down!)	* (Dodge Queen's attacks with ~1, ~2, and ~3!)

Version 1.06#

Released on September 23, 2021.

• Fixed an issue where Spamton NEO's ShadowCrystal didn't carry over to the player's Light World inventory as Glass.
• Fixed an issue where Sweet Cap'n Cakes' attacks, which are synced to their battle music, lasted an unusually long time.
• If the player fires six to ten charged shots during the Spamton NEO fight via a glitch that allows them to do so in quick succession (pressing Z while holding down Enter, or vice-versa), he will become visibly angry and his attacks will increase in strength. The latter effect amplifies with continued use of the glitch, though becomes more lenient if the player repeatedly loses the fight.
• Fixed the "Wrong Warping" bug. It now requires holding X and C to execute, so that the bug doesn't affect casual players while still being accessible to speedrunners.
• Unspecified additional bugfixes.
• The unused arcade machine placeholder sprite was updated to remove any Xbox branding.

Version 1.07#

Released on September 30, 2021. Also known as version 1.03 on PS4 and version 1.03b on Switch.

• The X key can now be held down to reduce the SOUL's movement speed on the Bullet Board by 50%, making it easier to navigate tight spaces between certain projectiles.
• Defeating Jevil in Chapter 1 now adds a ShadowCrystal to the Key Items section of the inventory, which can be imported to Chapter 2.
• Checking Kris' bed after completing Chapter 2 once now allows them to instantly skip to the Cyber World, similarly to in Chapter 1.
• Lancer has new dialogue during the Chapter 2 prologue when importing data from a Chapter 1 file that saw enemies defeated with violence. Lancer now clarifies that he used his new powers as king to grant the party amnesty, allowing Castle Town's residents to forgive them.
• Spamton NEO becomes "subtly more difficult" when angered by the consecutive charged shot glitch: some of his later attacks like the second phone wave attack will come much earlier in the fight, and the heart attacks' bullets will be more randomized to make it trickier to dodge.
• Ralsei's FluffyGuard R-Action in the Spamton NEO fight is altered to allow the player to pause the shield's rotation with the X key.
• The Pipis enemies you fight in the Weird Route now have a 1% chance of becoming Ms. Pipis, which functions identically to a regular Pipis apart from having a pink bow added to its sprite. (Presumably, this is what the stretched "Pipis Fanservice" line in the official changelog is referring to.)

Version 1.08#

Released on February 22, 2022. Also known as version 1.04 on PS4 and Switch.

• The game is now built with GameMaker Studio 2 2022.1.
• Sprites of the two chapters are now put into their own texture group. Only when the player chooses to play one of the chapters, the game will load the texture group for it.
  • As a part of this system, a new room has been added for reloading the game, causing room IDs to shift by one, which wound up causing a critical save file bug.
• A loading screen was added for consoles.
• Most debug messages were removed.
• The copyright dates in the title screens were changed to 2018-2022.
• During a battle, if the cancel button was already held when the attack starts, movement speed won't be slowed.
• Made it so that if you freeze some but not all enemies in a battle, the encounter is always determined to be ended by violence, fixing an exploit that could be utilized for stat farming.
• Rouxls has unique lines when defeated violently.

Character	Text
Rouxls	* So thou hath beateneth The Crappeth out of Me.
Rouxls	* I supposest that means thou thinkest thoust hath Won?
Ralsei	* Umm... morally, no. * Physically... yes.
Rouxls	* Well shivereth my timbereth, you little Bimbo!
Rouxls	* For in a battle of TRUE Powere, Rouxls... shall RULE!

• A glitch in which the player is able to clip through the rolling pottery/Pipis obstacles in Queen's mansion is incorporated as a proper gameplay feature. Doing so now causes them to break apart and fly offscreen, enabling the use of this technique in glitchless speedruns.
• Swatchlings now display the correct dialog in battle.
• The flag tracking who you gave the gift to in Cyber City is no longer forcibly set to "given to Ralsei" in the boat ride cutscene's code, so Susie's present correctly appears in her room if you gave her the gift. However, the dialogue that is supposed to appear if you didn't give the present to Ralsei has also been made deliberately unreachable - the developers' intent likely was to simply make the dialogue unreachable. Save files made with older versions that are past the boat ride are not affected by this fix.
• The classroom's appearance has been changed.
• Fixed more places where the music would sometimes overlap on console.
• Changed the way files are saved on console. This fixes a bug in the PS4 version where save files could become corrupt under certain circumstances. Also, the game now checks for save validity, and notifies you if a save is corrupt.
• The VCR icons in the Spamton NEO fight now properly displays during the final attack in all circumstances, rather than just in the Weird Route.
• The Spamton NEO fight now has a new smoke effect after the final attack.
• Ralsei now will snap Spamton NEO's wires desperately as intended.
• The doll of Yoki (one of Temmie's characters) in Seam's shop was updated in Chapter 2 to match her redesign in Temmie's game Dweller's Empty Path. The old design was mistakenly still used during Chapter 1, which this update fixes.

Prior to Version 1.08	Version 1.08 onwards

• The description for Kris' ACT "spell" is changed.

To do: Compare the old and new ACT descriptions.

• Changed the TP cost of X-Slash and TurboDodge from 62.5 to 62, presumably to prevent TP rounding errors.
• Properly refers to the objects created with the FluffyGuard ACT in Spamton NEO as "fluff balls" instead of "tiny Ralsei". The latter seems to be a leftover from early development, in which the sprites for FluffyGuard were indeed miniature Ralsei heads.

v1.00	v1.08
* You have too many tiny Ralsei!	* Too many fluff balls! * Can't make any more!

• The ending of the Spamton NEO fight now sets the HP of any party members to 1 if their HP is below 1.
• The amount of healed HP in Spamton fights when you press F1 is now rounded.
• Fixed a typo in the following dialogue.

• The "[NO TEXT]" placeholder strings are now only shown if debug mode is enabled.
• Added unreachable code to spawn the unused birthday dog "attack" in the Queen fight, supposedly for Taxiderby's presentation of the "attack".
• Sweet Cap'n Cakes will now only target Kris on the first, third, and fifth turns, aiding a speedrun strategy in which the first phase of the fight is ended prematurely by downing Kris as soon as possible (enabling Susie and Ralsei to learn S-Action and R-Action without requiring Kris to use the "Dance" ACT on Sweet, Cap'n, and K_K at least once each).
  • For some reason, if Sweet is the only one that's dancing, Sweet Cap'n Cakes will target everyone no matter the turn.
• Many other miscellaneous bugfixes.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Maybe check the JSON language files, as well as sprites.

The changelog claims that the update "fixed an error where Alphys had the wrong face during a certain dialogue", but in fact, nothing related to that was changed.

This version was quickly reverted for PCs, after a bug with loading save files (due to the change in room order, loading saves puts you in the wrong place) was discovered.

Version 1.09#

Released on February 24th, 2022. Also known as 1.05 on PS4 and Switch. No changelogs were published for this version.

• Changes were (explicitly or inexplicitly) made in response to the v1.08 save file bug.
  • When a save file is loaded, the game now checks if the destination room of the save file is in a "valid rooms" list; if it isn't, it adds 1 to the destination room ID - likely to compensate for the extra room added by v1.08 - and does the check again just to be sure. However, if the second check fails, the original ID is not restored, causing unintended results.
  • Added a workaround for loading saves unexpectedly putting you into the empty version of Castle Town.
  • The game version is now saved to save files.
• Additional features were added to Chapter 1's Debug Mode, likely to assist with creating the valid room list.
  • The plot value is now shown on screen.
  • You can now change the game speed by pressing ~ or Ctrl+~ on the keyboard. ~ changes the speed to 150 FPS, while Ctrl+~ changes the speed to 10 FPS. Pressing the shortcut again changes the game speed back to 30 FPS.
• More efforts were made to cripple the debug mode.
  • The debug mode switch is now properly set to disabled in the chapter select screen.
  • Removed all code in obj_debugProfiler and obj_jean_debug, presumably as a workaround for a bug where you can get some Chapter 2 debug features in Chapter 1, by loading Chapter 2 and then quickly exiting to the Chapter Select screen and entering Chapter 1. This introduces a crash when cutscenes are played in Chapter 2 with the Debug Mode enabled.
• Fixed a bug with the slow soul mode, where holding C during a battle and pressing Z toggles it off.
• Made it so that interacting with the bed in the Castle Dojo registers the interaction to flag 412, allowing the originally unreachable "You retained the title of Bed Inspector." dialogue when you interact with Noelle's bed to appear as intended. Previously, this was only done by the bed in the unused room_cc_clover room.
• Added back the code that shows Undertale‍ '​s Switch eShop page in the console-only splash screen, which was accidentally removed in v1.08.

Version 1.10#

Released on February 25th, 2022. Also known as 1.06 on PS4 and Switch.

• Changes to the room validation system were made.
  • The original destination room ID is now restored if the second check fails.
  • It is now skipped if a temporary save file is being loaded.
  • The Maze of Death room in Chapter 1 was added to the "valid rooms" list.
  • It now prints additional debugging messages.
  • When saving in debug mode, the game now calls scr_add_valid_room with the current chapter, the current room, and the current plot value. What this does is currently unknown, as the function appears to be dummied out in the release version.

Version 1.12#

Released on April 11, 2022, under the chapter1.2.112.windows7fix beta branch on Steam. Possibly claims to be 1.07 when run on PS4 and Switch.

• Updated GameMaker version to 2022.2, which includes a fix to the game crashing on Windows 7. This meant YoYo Games' new Steamworks extension has to be used in Steam builds, causing the game to carry leftovers from it.

• Chapter Select screen no longer erroneously forces fullscreen.
• A weird change has been introduced to Chapter 1's initialization code, setting global.chapter to 1, and setting global.plot & global.filechoice to 0. (TODO)
• Changes were made to the save system; a notable change is the use of custom room IDs. (TODO)

• Standardized audio volume between Chapter 1 and Chapter 2. Game volume is now consistently initialized as 60%, rather than 100% only in Chapter 1.
• Berdly's "spear blast bullet" objects as well as some Giga Queen attacks now set the volume of snd_rocket when that sound gets played.
• Added a variant of the snd_rocket sound for the Queen paintings in the Mansion, as well as another one for Spamton NEO in the "WHAT!? IT'S FOR ME!?" "attack".

• Adjusted the size of the cutscene trigger in room_dw_cyber_rollercoaster.
• Possible visual adjustments to the cityscape background.

• Fixed a softlock when Ralsei tries to ACT on a Maus as it is Upgraded.
• The cheese maze no longer appears after aborting the Weird Route, making it impossible to use SnowGrave on normal enemies.

• The music now stops after Queen's dialogue if she is violently defeated.
• Fixed a visual bug with GIGA Queen's speech before her battle.
• Giga Queen's fire breath attack can no longer happen instead of the final attack.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Queen's wine bubbles now change depth at 1 pixel lower? - They seem to have fixed input bugs in the chapter 1 menu. Not entirely sure to what extent, but there's code to prevent inputs now - what, the main menu or like battle menu? cos i kinda think If it’s battle it could be to patch that thing in the susie lancer fight - like the save menu. the uhhh.... main chapter save menu when you first load in Shayy's bug report to DR devs

To do: Changes

Oddly, the build timestamp of the Windows build of this version is Mon Mar 28 2022 03:06:25 GMT+0000, but the build timestamp for the Mac OS X build (which uses a newer GameMaker version) is Wed Apr 06 2022 02:07:22 GMT+0000.

Version 1.13#

Released on April 12, 2022, under the chapter1.2.112.windows7fix beta branch on Steam. Still claims to be 1.07 when run on PS4 and Switch.

To do: Changes

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Anyway, as for 1.13 code changes - they just fixed scr_dogcheck and the file load process Although, someone might want to check to see that chapter 1 saves work properly

Version 1.14#

Released on April 14, 2022, under the chapter1.2.112.windows7fix beta branch on Steam. Still claims to be 1.07 when run on PS4 and Switch.

To do: Changes

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Dogcheck is gone (1.14 patch) Also they changed chapter 1 loading Now it properly has the code that adds 10000 and that's it

Version 1.15#

Released on June 6, 2022, under the chapter1.2.112.windows7fix beta branch on Steam. Still claims to be 1.07 when run on PS4 and Switch.

• The Steamworks extension is now initialized properly.
• The logic to destroy the Cheese Maze after failing the Weird Route now also checks the internal route progression. Fixes a bug where the cheese maze would immediately disappear if the Weird Route was started and ignored, but only aborted during the maze.
• Berdly's halberd has been redrawn to be more consistent.
• Position checks were altered for the bullets in the Queen fight.
• Chapter 1 now ensures the invincibility timer is set to 1 after starting/loading a game and after beating the King fight. This fixes a bug where heightened invincibility frames could be retained from the King battle.
• Fixed visual issues with the speedlines effect of the GIGA Queen fight.
• Fixed a rendering bug with a tile in room_dw_city_big_3.
