  • Hey guys. I'm trying to mod the game for a video idea I had. I'm just wondering if any of you can confirm that this link is safe?
  • how do i disable dogcheck in undertale v1.11 pls help i want to acess soundtest room
  • Question
    ...hmm, looks like there only used to be. You could try building the tool yourself, I guess, or you could downgrade: https://github.com/krzys-h/UndertaleModTool/releases/tag/
  • i need help im new
  • Uh oh stink

    Not sure where you can get the sprite sheets straight up but there's a great tool for unpacking assets from Deltarune and other Game Maker games here: https://github.com/krzys-h/UndertaleModTool/releases
  • How do you mod deltarune on mac?
    Since most programs for modding Undertale/Deltarune like UndertaleModTool are Windows only, you will need a program like Wine to run it.
  • Sounds extraction?

    Was looking for the same thing. Found what i needed using this: https://github.com/krzys-h/UndertaleModTool/releases. It works with Deltarune. To export you need to select in upper menu: Scripts - Unpack assets - ExportAllSounds.csx. It asked something about groups, i selected yes. Queen's sounds were in "audiogroup_default" folder.
  • Sounds Extraction?
    The extracting process will vary by game/engine. Deltarune is popular enough to have a pretty strong modding scene: the UndertaleModTool can do what you need.
  • This game has incredible modding potential. Let me explain why

    Best chance is helping UndertaleModTool to update for GM 2.3
  • Alternative Ralsei's question? (Acid tunnel scene)
    Compiled UndertaleModTool myself from current GitHub code with Visual Studio 2019. Because "Release 1 of 0.4.0" is not decompiling all of Chapter 2 code (as you said).
  • Deltarune files on steam
  • Looking for spell healing/damage calculations and element information
    You can go here to download UMT's automated builds until they release a version with decomp for ch2: https://github.com/krzys-h/UndertaleModTool/actions/workflows/build.yml Click on the latest one and scroll down for the download.
  • How do I make a program stop forcing itself to run in 32 bit?
    You're talking about this tool: https://github.com/krzys-h/UndertaleModTool/releases .. ?
  • tried to enable debug mode by toggle in deltarune c2 with undertalemodtool and got this error
    That script doesn't work on Chapter 2. If you download the latest build (scroll down to artifacts), use Ch2 Debug.csx. Or do it manually I guess.
  • gone full circle...?

    Just because they haven't responded yet I think is This using the data.win
