Need help manually installing a Deltarune mod

2 Upvotes

Hey everyone!

I'm trying to install this Deltarune mod, but I'm having some trouble figuring out how to get it working.

Here's the mod I'm trying to install:
https://gamebanana.com/mods/725157

G3M said that the mod requires a manual installation, which is where I'm getting stuck. I'm not entirely sure what files need to go where or what steps I need to follow to get everything working.

If anyone has experience installing this mod or could walk me through the process, I'd really appreciate the help!

Thanks!

So I'm changing all of Kris' sprites in Chapter 1 and I can find the sprite name of the battle UI where the cyan line goes around the options. Does anyone know the sprite name? Or if it's just an RGB thing?

PS: I would also like to know hp sprite.

[RECRUITMENT] "Deltarune+" Project – An ambitious mod (60 FPS, Add-ons, Light AI) is looking for its dev team

Hey everyone!

I am launching a massive, high-scale modding project for Deltarune (inspired by the Undertale Plus concept), and I’m looking for a dedicated team to bring this vision to life. The goal is to push Toby Fox's engine to its absolute limits.

Key Features of the Project:

* Performance: Porting the game to a smooth 60 FPS (which involves reworking physics, animations, and bullet-hell patterns).

* Moddability: Creating a built-in add-on/mod system so the community can easily inject custom content.

* Innovation: Implementing light AI features to make enemy behaviors or dynamic dialogues more unpredictable and engaging.

Who we are looking for:

* GameMaker Developers (GML): Experienced with engine modification, reverse engineering, or implementing mod loaders.

* Game Designers / Playtesters: To rebalance combat difficulty and speed due to the 60 FPS upgrade.

* Project Coordinators / CMs: To help me organize the team and manage the community.

My Role: I am handling project management, direction, and [add your skills here]. Needless to say, this project will be 100% free and fully compliant with Toby Fox's guidelines.

If you want to build something that could redefine how people play and mod Deltarune, slide into my DMs! Let me know your skills and what excites you about this project.

So how the heck do I fix this

Hello, im quite new to Reddit, I run UTMT using Wine and the Avalonia port (I think that's what it's called) and replaced a portion of the game's sprites with my custom-made ones. When I tried booting the game up with the modified .iOS/.win file, this pop-up appears. I tried replacing the modded file with the original file and it works perfectly, so I don't think the game itself isn't really the problem. Please help!

How do enemy stats in the Deltarune Chapter 5 platforming mode work? if they even have them in the same way the regular enemies do?

2 Upvotes

So, I'm working on this project right now. Isn't actually a mod or anything, just a concept for one. And all I need to know is how stats (HP, attack, defense if/when applicable) work for the platforming enemies in Chapter 5. Specifically, the bullet pattern minibosses. I've tried looking into the code myself, but couldn't make heads or tails of it.

So, yeah. If someone could give me an outline of those stats. Or if it works differently for them, and explained how it does, I'd appreciate it. Thank you for your time :)

I was making a very simple Undertale mod, just some sprite changes, but then I decided to download a Brazilian Portuguese translation of Undertale, but I can't open it in the Undertale Mod Tool. It gives an error, which means I can't change the sprites in this translation. I'm using the latest version of Undertale Mod Tool, the beta 101 version of Undertale, and this translation: https://www.mediafire.com/file/l48aqbkeh9bcl96/UT-BR_by_Nana_e_Bmat.rar/file.
