Debug Mode

Edit the following bytes in data.win.

• 3E8144 and 3E8138: Set to 01. Enables debug mode.
• 3E8568: Set to 00. Disables the 'dogcheck', allowing you to enter rooms above 130 via save file editing.

Enabling debug mode will show a few additional things during the game:

• The frames per second will be printed in the top left, in red.
• Areas with enemies will have a red and cyan box to the upper-left and lower-right of your character.
• Possibly others.

Additional hotkeys are available as well, some of which are reused from the previous game.

• O: Sets the FPS cap to 3.
• P: Sets the FPS cap to 60.
• Z and other "action" buttons: Displays a small rectangle in front of you for one frame, indicating the 'interaction' hitbox.
• R: Restarts the game. No need to press it 7 times.
• S: Opens the save dialog anywhere. Using it will usually unlock your movement, if it was locked by a script.
• L: Immediately reloads your save.
• D: When held down, pushing 3 through 9 will teleport you to various rooms starting at the dark world to the middle of the game. The plot and party variables are updated to bring the story to the correct position.
• W: When held down, pushing 1 through 6 will teleport you to various rooms near the end of the game. The plot and party variables are updated to bring the story to the correct position.
• C: When held down, text will automatically advance as if you were using the Wrist Protector item.
• Ins: Moves you to the previous room by internal order.
• Del: Moves you to the next room.
• F10: Takes a screenshot and saves it within the DELTARUNE folder.

Additionally, there are various context-specific debug commands.

When fighting King Boss:

• Space: Increases the attack number by 1.
• Backspace: Reduces the attack number by 1.

"Unused" Music

Dogcheck's back, baby, and with an all new song. Setting your savefile to start you in a room over 130 will play this chill tune while a sleeping dog replaces whatever you were trying to sneak into.

Unused Text

Within the lang files (lang/lang_en.json, lang/lang_ja.json) are some conspicuously unused messages:

  "UNUSED_slash_UNUSED_gml_1_0": "Where...",
  "UNUSED_slash_UNUSED_gml_2_0": "Where am I?",
  "UNUSED_slash_UNUSED_gml_3_0": "Hello...? Anyone...?",
  "UNUSED_slash_UNUSED_gml_4_0": "Is... is anybody out there...?",
  "UNUSED_slash_UNUSED_gml_5_0": "Someone!? Anyone!? Can anyone hear me!?",
  "UNUSED_slash_UNUSED_gml_6_0": "...",
  "UNUSED_slash_UNUSED_gml_7_0": "It's dark.",
  "UNUSED_slash_UNUSED_gml_8_0": "It's so dark here.",
  "UNUSED_slash_UNUSED_gml_9_0": "Someone, anyone, if you can hear me...",
  "UNUSED_slash_UNUSED_gml_10_0": "Say something... please...",

Unused Graphics

Beach Area

An early sketch of the beach area room_beach exists, in the same style as the Lab and Undyne's Room sketches from the previous game.

Early Ending Sequence

Early	Final

Early	Final

Early versions of the sprites in the ending cutscene still exist, under spr_dkris_grabheart_old and spr_dkris_pullheart_old. In general, the old versions lack shading that the final ones do. Kris has less bedhead in his early sprites, and they all lack the stripe on his shirt.

Unused Rooms

• Room 3, room_torroom, is an empty (all-black) room. Assumedly it would be Toriel's room in her house, but the door is locked.
• Room 7, room_town_northwest, is an empty black room as well. It was presumably the area behind the closed off gates within the town.
• Room 11, room_town_apartments, is an empty black room as well, though larger than room_torroom. It may have been for the apartments in the town, which cannot be entered.
