Important
DELTAModKit is in active development. There are many known visual bugs present and I'm aware of certain things (such as the main characters' attack, defense and magic values not being accurate to the real game's chapters). If you find any issues, you can help out by creating an issue or opening a pull request.
The most robust, feature-complete DELTARUNE GameMaker Studio 2 decompilation / port, enhanced with a multitude of tweaks designed to make the game easier to mod.
Caution
This project does NOT allow for piracy of DELTARUNE Chapter 3 and 4. It is simply a base from which you can start building your own DELTARUNE chapter/fangame. Most assets which have been included in the project can be found in the free Steam demo for Chapter 1 and 2.
To start playing around with DELTAModKit, you have to download GameMaker Beta. The project uses the latest BETA version Beta v2024.1400.0.838. It will not work on non-Beta versions.

The hearts of my modular reimplementations of the character, item, spell and equipment systems all live in the folder Custom > Scripts > Configs. I tried naming everything in an easy-to-understand way, but feel free to reach out if you encounter any issues. Provided in the Custom > Objects folder is an example cutscene for working with the Cutscene System and some helper markers to assist with character placement in cutscenes
