Cutscene Codenames#

While cutscene objects are simply named after what happens in the scene in Chapter 1 and then "scene" in order of when the scene happens in Chapter 2, Chapters 3 onward use specific codenames to refer to what point in the story the scenes take place.

Full rhythm game track list#

ID	Alt. ID (Ch4+)	OST Name	In-Game Name (if different)	First Appears	Used in Final	Charted?	Notes
0	3	Raise Up Your Bat	Lightners Live (Chapter 3) Raise Up Your Bat (Chapter 4)	Chapter 3	Used	Charted	This is the chart used for the Round 2 minigame, inside the A-Rank room, and playable in Castle Town in Chapter 4 and 5.
1	N/A	Sound Check	Soundcheck	Chapter 3	Used	Charted	Used as the rhythm game practice song in Chapter 3. Can also be played in Chapter 4 through freeplay mode. Unused in Chapter 5.
2	4	It's TV Time!	Tenna boss	Chapter 3	Used	Charted	This is the chart used during the boss fight with Tenna and playable in Castle Town in Chapter 4 and 5. Can only be played in short bursts in Chapter 3, but the whole song is charted and technically playable.
3	N/A	MIKE, The BOARD, please!	How To Play	Chapter 3	Used	Charted	Has a custom guitar track on top of the song. Normally used as part of the tutorial and can't be played as a song. It can be played properly in Chapter 4 through freeplay mode, although this has a tendency to crash the game. Unused in Chapter 5.
4	N/A	N/A	Board 4	Chapter 3	Used	Charted	Used for the rhythm game gag during Tenna's freakout in Chapter 3. Has a single note and plays a sped-up version of NOW'S YOUR CHANCE TO BE A. Can also be played in Chapter 4 through freeplay mode. Unused in Chapter 5.
5	N/A	Ruder Buster	Rude Buster (Boss)	Chapter 3	Unused	Partially Charted	This song has about 5 seconds of charting for guitar. If in Chapter 3 specifically you continue to wait around after it ends, the chart will switch to Raise Up Your Bat and its solo switching logic will activate, causing the song to erratically jump around. Charting was removed in Chapter 5.
6	N/A	Vapor Buster	Rude Buster (Vapor)	Chapter 3	Unused	Partially Charted	Song instantly ends when played in the normal minigame, but there's about 30 seconds of charting when viewed in the editor. Charting was removed in Chapter 5.
7	N/A	N/A	tenna_battle_old	Chapter 3	Unused	Uncharted	Despite the song file being left over, it is byte-for-byte identical to the final tenna_battle. The song has code to end earlier.
8	0	Rude Buster		Chapter 4	Unused	Uncharted	There's additional code and audio to support this song in Castle Town.
9	1	Field of Hopes and Dreams		Chapter 4	Unused	Uncharted	There's additional code and audio to support this song in Castle Town.
10	2	Knock You Down (Rhythm Ver.)	Knock You Down!!	Chapter 4	Used	Charted	Available in Castle Town.
11	5	The Third Sanctuary	Third Sanctuary	Chapter 5	Unused	Charted	This got a unique remix not featured on the OST. It's significantly shorter and adds a guitar to go with the main rhythm.
12	6	Flower Man		Chapter 5	Unused	Uncharted	This is the only song to be added to the rhythm game code that's from the same chapter. It's not set up to have the lyrics from Flowery's boss fight display, unfortunately.
13	7	A DARK ZONE		Chapter 5	Unused	Uncharted	This uniquely adds the dancing pumpkins from the Jackenstein fight on the bottom of the screen and shifts the UI up, which visually breaks menus.
14	8	N/A	reserved	Chapter 5	Unused	Uncharted	No actual definition exists, so attempting to play the song leads to inconsistent behavior. These IDs are skipped over and labeled as "reserved" in English, but the Japanese text indicates that Cutie Mew Mew Magic was originally placed here and a variable name in A DARK ZONE's code indicates that it likely included special visuals.
15	9	4rd Sanctuary		Chapter 5	Used	Charted	Available in Castle Town. This is the only additional used song added to the minigame in Chapter 5.

Useful tools#

Due to Deltarune's debug mode being mostly stripped out, navigating the game in order to access unused content in its full context can be a bit of a pain. There are some community tools that have been made to make this process easier, either by supplementing debug mode or directly reimplementing its features:

UndertaleModTool's built-in Fancy Room Select script adds a menu that can be used to warp directly to any room in the game and has a search bar.
Deltarune Debug Plus reimplements most known debug features (from Chapter 3 and 4 and the demos) across all chapters, including the 8-4 menu, which has a room select of its own (though with no search bar).

Manually enabling debug mode#

You shouldn't need to manually enable debug mode in most cases, but if UndertaleModTool's debug enabler script and/or the tools listed above aren't working for one reason or another, here's how to do it.

All chapters

Edit obj_initializer2's Create event to set global.debug to true instead of false.

Chapter 1

To disable Dogcheck in debug mode, edit scr_dogcheck to add the following code at the top of the function:

    if (scr_debug())
        return 0;

Note that very few debug features remain in this chapter, so it might not obviously appear to be enabled.

Chapter 2

Edit scr_debug to actually return global.debug; instead of always returning zero.
Note that very few debug features remain in this chapter, so it might not obviously appear to be enabled.

Chapter 3

Below the line you changed in obj_initializer2's Create event, add a new line with global.chemg_show_room = 1;. This fixes a crash when loading boards. (The 1 can optionally be changed to a 0 to disable the room name display.)

Chapter 4

In scr_flag_get inside the function scr_flag_name_get(), replace the first line of the function with the following. This fixes a crash when story flags are set.

    var v = !variable_global_exists("flagname") ? "" : global.flagname[arg0];

Chapter 5

Edit scr_get_room_by_id to remove new scr_room(rm_blank, 50094), from the room list, as this room doesn't exist and will cause a crash when loading.
Edit scr_save to remove the block of code at the top that runs if debug mode is enabled, as it references the same nonexistent room and will cause a crash when saving.
Note that less debug features remain in this chapter than 3 and 4, but there is still more than 1 and 2.
