Chapter 1 was ported to consoles on February 28, 2019. Minor changes were made.[2]
- Added borders for console versions of Chapter 1, illustrated by Temmie Chang.[3]
- Changed "Kris got the Hot Chocolate." to "You got the Hot Chocolate.", matching other item acquisition text.
- Added a version number.
- Miscellaneous fixes and typo corrections.
Exclusively on Nintendo Switch:
Initial release on September 17, 2021.[6]
v1.002 added a question mark icon for unknown controller inputs.
v1.003 fixed several crashes relating to game controller configuration on September 18, 2021.[9]
v1.004 fixed several miscellaneous crashes and softlocks on September 19, 2021.[10]
v1.0.5 was released on September 21, 2021.[11]
- Added an option to give up during the GIGA Queen battle.
- Added several autosaves, providing more convenient respawns upon getting a Game Over in certain places:
- Before the Queen battle. This save also restores party HP.
- Before the teacup ride in the Mansion Basement.
- Moved the autosave before the Spamton NEO battle, now allowing Kris to not insert the Disk and simply leave.
- Fixed a bug where Noelle would retain her SnowGrave spell if Berdly was spared in his Cyber City battle. Defeating him with IceShock or melee attacks still allows her to retain the spell, however.
- Miscellaneous bugfixes.
v1.06 was released on September 23, 2021.[12]
- Allowed the Glass to properly appear in the inventory if Kris has a Shadow Crystal.
- Fixed a bug where Sweet Cap'n Cakes's attacks could be extremely long.
- Added an anger mechanic to the Spamton NEO battle. Firing many "big shots" by using the "[CONFIRM]" and "[Enter]" keys at the same time now causes Spamton to turn red, gain higher ATK, and cause some late fight attacks to occur earlier on.
- Fixed an issue with warping to a room's default point if a room transition was only touched momentarily. It can still be triggered by holding "[CANCEL]" and "[MENU]" button; this was likely intended for speedrunners, who always hold these keys to skip text and run.
- Miscellaneous bugfixes.
v1.07 (v1.03 on console) was released on September 30, 2021.[13]
- Added the functionality of holding "[CANCEL]" button during attacks to slow the SOUL, allowing for more precise movement in battle.
- Defeating Jevil now gives a Shadow Crystal immediately, like Spamton NEO. New flavor text was added for using the Shadow Crystal or Glass in Chapter 1.
- Added the ability to skip to the Cyber World using Kris's bed if Chapter 2 has already been completed, like Chapter 1.
- Added dialogue if enemies were defeated violently in Chapter 1.
- Slight changes to Spamton NEO's difficulty.
- Improved "FluffyGuard", Ralsei's R-Action against Spamton NEO, by allowing holding "[CANCEL]" button to stop the ball's rotation.
- Added the rare "Ms. Pipis" variant of the Pipis enemy.
v1.08 (v1.04 on console) was released on February 23, 2022,[14] and retracted several hours later due to a bug.[15]
- Added new dialogue after the Rouxls Kaard battle if Rouxls was defeated violently.
- Fixed a bug where Ralsei would not snap desperately against Spamton NEO.
- Changed the description of ACT in the Power menu in Chapter 2 from "Do all sorts of things. It isn't magic." to "You can do many things. Don't confuse it with magic."
- Fixed a bug with interacting with rolling pots in Queen's Mansion: they now fly away along with their Swatchling rather than disappear.
- Fixed a bug where orange or green Swatchlings would copy incorrect text in battle.
- Changed Alphys's classroom in Chapter 2 to match Chapter 1 in coloration.
- Fixed a bug where using Noelle's IceShock on one enemy and sparing the other would cause the encounter to respawn, allowing grinding for infinite AT/Magic.
- Fixed a bug where Spamton NEO's final attack would not correctly display "WRECK", "PAUSE", and "SPEW".
- Fixed a bug where the flag for giving a gift in Cyber City was always reset to 1 (given to Ralsei). Added a Susie plushie and dialogue if it is given to her.
- Added a smoke effect after Spamton NEO's final attack.
- Holding "[CANCEL]" button through the start of an attack no longer slows the SOUL, allowing it to be held constantly while remaining at full speed. Pressing "[MENU]" and "[CONFIRM]" button during an attack plays a sound and toggles SOUL-slowing.
- Corrupted save files by offsetting room IDs.
- Miscellaneous bugfixes.
v1.09 (v1.05 on console) was released on February 24, 2022.
- Restored all changes from v1.08 after its retraction.
- Attempted a fix of the save-corrupting room ID bug; caused several other glitches.
- Removed the SOUL-slowing toggle with "[MENU]" and "[CONFIRM]" button.
- Fix a bug where the Chapter 2 Bed Inspector title was unobtainable.

v1.12 was available as a Steam beta on April 10, 2022.[17] It contained several bugfixes for the save system and running on Windows 7.
- Fixed the game running on Windows 7.
- Further changed the room system to better distinguish between Chapters.
- Fixed a bug where the game would switch to fullscreen on the Chapter Select screen.
- The cheese maze no longer appears after aborting the Weird Route, including the single cheese before the maze, making it impossible to use SnowGrave on normal enemies.

- GIGA Queen can no longer reuse her fire breath attack in place of her final attack.

- The music now stops after Queen's dialogue if she was violently defeated.
v1.13 was available as a Steam beta on April 12, 2022.[18] It contained more minor bugfixes, especially for the new room ID system.

v1.15 is available as a Steam beta since June 6, 2022.[19] It contained several minor bugfixes.

- Fixed a rendering bug against GIGA Queen.
- Fixed a rendering bug with a tile in Cyber City.
v1.16 was available as a Steam beta, separate from 1.15, as well as on itch.io on November 25, 2024.[20] It updated the GameMaker version to use a new method of delineating Chapters within the game data.[21]
- Fixed Swatch using a beta overworld sprite in the Castle Town Cafe.
- Removed a stray green pixel from Susie's hurt sprite.
- Removed the drone sound from the Chapter Select screen.
- Added hours to the save file display.
- Introduced several bugs, mostly relating to GameMaker's updates. Most of these were fixed by v1.17.
- Entering "GASTER" during the introduction sequence redirects the player to the start of the currently selected Chapter, instead of to the Chapter Select screen.
v1.17 was available as a Steam beta and on itch.io, replacing v1.16, on November 26, 2024.[22] It fixes bugs introduced by GameMaker's changes since v1.15.

Toby Fox has noted there will likely not be another update to Deltarune unless GameMaker updates game_change.

Deltarune Chapter 2 was released as a free update to Chapter 1 on PlayStation 4[24] and Nintendo Switch[25] on September 23, 2021 under the title Deltarune Chapter 1&2. While its v1.00 release predates the PC v1.00 due to testing requirements, later versions were synchronized with different version numbers.
There are two distinct versions of the Nintendo Switch demo: The version released in 2021 as its own title, and the version released in 2025 as the demo for the full game. The 2025 version has "Demo" in its title and icon, and Save Data is structured differently in the two demos, but otherwise they are identical.[26] The 2021 demo was delisted from the Nintendo Switch eShop on May 20, 2025, before the 2025 demo became available. The latest versions of both demos are labelled v1.06.
The following changes apply in the console versions:
- At the start of Chapter 2, the LightCandy can be obtained as long as a Chapter 1 Completion FILE exists, regardless of whether the Chapter 2 SAVE file was continued from Chapter 1 (and regardless of Kris's actions in Chapter 1).
Versions as of Deltarune's official purchasable release, starting from June 4, 2025.[27]
Added as of v1.02 patch on July 7, 2025.[28]
Added as of v1.03 patch on July 22, 2025.[29]
Added as of v1.04 patch on August 4, 2025.[30]
- Fixed a bug where enemies were not properly tracked if they were defeated by Susie before she officially joins the party. It has been a bug since the 2018 Chapter 1 Demo, where it was possible to get the pacifist ending even if Susie defeated enemies with violence.
Added as of v1.03 patch on July 22, 2025.[29] It consists of patches primarily for console versions.
Added as of v1.04 patch on August 4, 2025.[30]
Added as of Steam Beta Branch v1.05 on August 25, 2025.[31]
- The behavior of collecting Jevil's Shadow Crystal and equipment from the Castle Town cliffs from a SAVE file where he was not defeated was changed. In the full release, the items are available if the current save slot matches one in which the Chapter 1 Shadow Crystal is recorded (which matches the behaviour of Chapter 4 with the other Shadow Crystal boss equipment); whereas in the demo version 1.19, they are available if the Chapter 1 Shadow Crystal was recorded on any save slot. The Devilsknife would take priority over the Jevilstail if both were collected on separate save slots; even if the Jevilstail was collected in the current save slot.
Added as of v1.03 patch on July 22, 2025.[29] It consists of patches primarily for console versions.
Added as of v1.04 patch on August 4, 2025.[30]

- On the Sword Route, if there is not enough room in the inventory for the Shadow Mantle, a chest containing it will appear in the Green Room instead.
Another hotfix patch, v1.01C, was added June 9, 2025. This update informs that patching hotfixes 1A and 1B will be ported to console versions.[34]

A bugfix patch added for all platforms for v1.02, added on July 7, 2025.[28]

- GameMaker was updated to fix a PlayStation-specific bug, which properly sets the game to run at 30 FPS instead of 31-32 FPS.

- Fix a combination of inputs that would crash the game in several shops.
- A couple other minor fixes.
The following changes apply in the console versions:

- A continuity error was fixed where Spamton could appear as the PuppetScarf in Chapter 3's Bonus Zone event while on the Weird Route. This glitch did not exist in any release of the PC version.
On the Nintendo Switch 2 version only, Mike's room, Mike, and Mike minigames are all different than other versions to make use of the Switch 2's unique control scheme.
In the Dark Sanctuary, a Cuptain can be found on a switch. Interacting with them mentions that this is "switch-exclusive content".
An update was released on June 23, 2025, in order to bring the contents of hotfixes v1.01A and v1.01B to the console versions. It is paired with Chapter 3.[35]

The game has achievements added to the game to comply with PlayStation requirements. There is also unique dialogue for earning no trophies.
On the PlayStation 5 version only, the game runs at 31 frames per second instead of the usual 30.
- In Chapter 1, this causes The Legend to play desynchronized with the game during that scene. This is not a problem for music-synced events in other Chapters because those ones actually wait for the music rather than being manually timed to be synchronized.
The following changes apply in the console versions:
- At the start of Chapter 2, the LightCandy can be obtained as long as a Chapter 1 Completion FILE exists, regardless of whether the Chapter 2 SAVE file was continued from Chapter 1 (and regardless of Kris's actions in Chapter 1).
