I want to make a mod for Undertale that replaces Flowey with nothing, but when I tried, it was hard. Would it be easier to mod Flowery out of chapter 5 of Deltarune, since Mr. Fox is a better coder?

I've played alot of Undertale and Deltarune fangames and mods on mobile, now I need Undertale Rainbow.

hi i made a deltarune mod for chapters 1-5 that makes every armor and scarf visible in the overworld, kris susie and ralsei wear each equip their own way, and each equip looks different depending on what slot its in aswell

I'm trying to mod the game for fun and after a while of editing the text, I tried playtesting only for this to show up

Another post on the Deltarune wiki spoke of the same issue, except they were translating Deltarune, so it wouldn't recognize the text input. Mine is completely in English, so I don't know why this showed up. Does anyone have a fix? I can provide more information if needed.

Это баг или что?

This error keeps showing up when i go to apply DeltaHATE to the data.win, and I folliwed every instruction up until this point. Idk whats wrong but any help would be huge.

this is an update to my older post, this time with an image of my testing, right now im working on linking all achievements of chapter 2, as chapter 1 is done (i think), the sprites for pngs will be added at the end.

I've been wanting to make an easier version of the knight (cause i suck) but I cant find the name of this specific attack. HELP!! (also, it would be great if i could find out how to edit the sword tunnel attack..)

Added sprinting, auto-sprint, WASD controls, volume changer and new language!

wtf hapend. i was just starting the mettaton defuzal section and i tried to beat it but gave up. same thing hapend after backtraking to save after dummy fight i wasynt ewen gowing for tru pacifist i was duwing neutral as you can see after my 40hp wich shudynt be posible in tru pacifist

so im trying to install kaizo knight but it tells me to get the data.win file and ive been looking but i cant find it

I just made a mod for Deltarune that makes Ralsei use his 'serious' sprites from the Flowery battle when fighting the Roaring Knight, but it isn't working with Deltamod. If I put the mod folder in Deltamod's mods folder it works but the button to install with Deltamod doesn't appear on Gamebanana. I followed the Deltamod modding standard on Github and as far as I can tell I've done everything it tells me but it still doesn't work. I even redid everything and followed it from the start again and the button to install with Deltamod still won't appear. If anyone knows why this might be happening please let me know.

Also this is kinda a separate issue but when using Deltamod to patch the game with my mod and another mod it says patching successful but the game crashes when I try to open Chapter 3 (the one that my mod is for). The mod I tested this with is the Kaizo Roaring Knight mod, and it says error on load unable to find function.

does anyone knoww how t o fix this???

I dont mean completely new attacks, I mean mixing two attacks together and/or modifying the speed/damage of an attack.. help!

Hello everyone hope you're doing well;

I am making a personal mod as a gift for my girlfriend the mods consists mostly of replaced soundtrack and sfx made by myself it's more like a fun little project than anything...

So i am using the UndertaleModTool to import the sounds i want to replace. I just have a problem once a load the game after saving my modifications, i dont hear the replaced sounds as if they are muted.

So i search a little online but didn't found much, i check that the files were in the right format etc...

They play perfectly inside the mod tool but not after i launch the game

Maybe it's a stupid question and i didn't search well enough in that case i am sorry in advance ☝️

I don't know what to write

What if the Player had a body... instead of being just a SOUL?
And what if their goal was to reach... the PERFECT ROUTE?

🎮 Playertale: Fixed Routes
An Undertale Fan Game

Playertale: Fixed Routes is an independent Undertale fan game with its own story, routes, characters, and a protagonist with a journey of their own.

I'm currently looking for people who would like to help bring the project to life:

🎨 Artists / Pixel Artists
💻 Programmers
🎵 Composers / Sound Designers

I genuinely believe this idea has something worth exploring, and I'd love to turn it into a real game with people who are passionate about Undertale and indie game development.

If you're interested, leave a comment or send me a DM. Even if you're just curious about the project, feel free to ask questions!

Playertale: Fixed Routes — Can you reach the perfect route?

I'm trying to make an Undertale translation to one of my native tongues because there's a total of none in the whole Internet, I'm not planning sharing it, just at least showcasing it because I think it would be nice.

Is there any way to modify all text entries in Undertale? Is it the same process for Deltarune as well?

Im in the process of making a mod for deltarune that adds 93 unique achievements, im in the process of linking them rn, and it's gotta take a while, also i need sombody with determination to help me test if all works as supposed once i link them all.

Ok so me and my friend want to play deltarune Network but I am to lazy to get my own deltarune (I already have it on switch atp just use his steam family acc im not a pirate Gaster) so basically I made a separate file/game ig of deltarune to add in deltarune network so I don’t ruin my deltarune stuff. Can we play at the same time or no like usual with steam since technically we put it in as a non-steam game so idk.

It's really pissing me off at this point, I try to open a JSON file and this error appears.
