UndertaleModTool VS gdsdecomp

UndertaleModTool although made for modding Undertale and Deltarune, it works with most game maker games. Just open the data.win file with it and you now have access to most of the game's code, sounds and sprites. Look for spritemaps/texturemaps and edit those. Just use it for modding and having fun and don't do anything illegal with it.

The naming screen script does not decompile correctly in UndertaleModTool, so you'll need to replace with a fixed version and then be careful not to trust any re-decompiled output. The others... that's just automatic line break messing you up. You probably have to rearrange the text so it fits better, maybe even add extra textboxes if you can't fit the translation.

You don't need GameMaker. You need UndertaleModTool, which can edit most game assets (rooms, code, strings) in a self-contained manner and export the rest (sprites, sounds) for external editing. Download a GUI build (it doesn't really matter which) from here: https://github.com/krzys-h/UndertaleModTool/releases

Thanks! This works. I download from here (picked this version, "GUI-windows-latest-Release-isBundled-true-isSingleFile-true.zip",idk what's the difference between them)

Tool Link: https://github.com/krzys-h/UndertaleModTool Yep, its an undertale tool, no joke. But its advertised as for multi-GM titles. though think I'm the first known one to use it on KZ lol or maybe not who knows.

you can use the deltarune mod tool to export all sprites from the data.win file

Everything is in game.unx, which is the same as data.win for Windows. You can dump certain asset types using UndertaleModTool, which has a Windows version (which oughta work through Wine) and a cross-platform CLI version. Download

After you've made a couple small games on your own - without being dependent on tutorials that handhold you through the process, that is - you should be able to pretty easily read and modify the decompiled code generated by UndertaleModTool after opening Undertale's/Deltarune's data file in it: https://github.com/krzys-h/UndertaleModTool

if it's a newer one like Undertale or Deltarune use UndertaleModTool

Tools like https://github.com/bruvzg/gdsdecomp exist, which is good if you need to recover your project.

The main contributor/developer behind Godot also released a very handy little tool that is capable of fully decompiling anything made with Godot:

https://github.com/bruvzg/gdsdecomp

It seesm exported game written in GDscript (I havnt tested with c#) is easily reversed into original source code state using tools (e.g. Godot RE Tools from https://github.com/bruvzg/gdsdecomp) and any one can take your source code.

With https://github.com/bruvzg/gdsdecomp it might as well be open-source anyway lmao

GDRE Tools, if you still have an exported artifact

Sounds like a job for GDRE Tools :)

unforunately godot games are unprotected by default. vast majority of godot games can be decompiled (and recompiled!) by gdsdecomp.

Pyinstaller has a single-executable option though, right ? As for reverse engineering, not sure that a godot game would be that much harder to decompile compared to pyinstaller, see example.

You should all try this: https://github.com/bruvzg/gdsdecomp
