If Deltarune is a GameMaker Studio 2 game, cant you just decompile it, open it in gms2, fix some issues in code, and then compile it for GX.GAMES?

This of course would only be possible if the game wasn't compiled with the YYC option (undertalemodtool would tell you if it was)

(also yes, you can decompile gamemaker 2 games, i maintain my own decompiler, and make my own web ports of Pizza Tower Mods, also in gamemaker 2)

This seems like a weird and honestly terrible and hard way of doing it

[burnedpopcorn]

btw, i dont own the game, so idk if its YYC compiled

Deltarune 1 and 2 are free on Steam.

[mafkee]

If I have time, I will try to see if they are yyc compiled

@burnedpopcorn YOOO I love your undertale port lol I'm surprised and not surprised that I found you here somehow

[SLG64]

@burnedpopcorn That might actually work. Do you have any suggestions as to where decompiling would be best?

[burnedpopcorn]

@SLG64

Decompiling it would allow you to get turn a data.win file (the main game file for GameMaker Games like DeltaRune) into a full GameMaker Project File

So basically you can retrieve the entire source code of the game using this method (without it having to be leaked) and compile it using the GameMaker IDE, the same way it would be compiled officially

You can then compile the game to ANY platform that GameMaker Studio 2 supports, such as Android, Linux, and The Browser using WebAssembly (WASM)

The WebAssembly Build can then be sent to GX.GAMES where it can be hosted for free (I would absolutely not recommend that, as they WILL take it down)

Or you can host the files on your own web server, like Github Pages

It might also be possible to compile to JavaScript, but JS is terrible for performance and compatibility, so I'd strongly recommend compiling to WASM

Also if you want to go down this route, I'd be willing to help for any issues you might come to

[SLG64]

Alright then, I will attempt to figure this out later before I continue the engine I am working on.

[burnedpopcorn]

Yeah

You'll need UndertaleModTool, and a Decompiling Script

UndertaleModTool doesn't have it bundled in already, because there's really only been three scripts ever made, and none have been donated

But you can find the UTMT build with the Script included in my repositories

So open Deltarune's data.win file, run the script, press OK (you don't need to change any Script settings), wait for it to finish, and run the output .yyp file in GameMaker

The code itself might still need some manual work to get working, but it shouldn't be too much of an issue to get it compiling and running

Another issue that could arise is asset indexes, where in code assets like sprites and rooms are referred to by their asset ID, instead of their asset name, so you'll have to fix all of those if you plan on having a moddable decomp, but if you're not changing anything major in code then it shouldn't matter

Compile and test the game to ensure compatibility and performance on the chosen platform(s).
Use WebAssembly if targeting the web, as suggested for better performance compared to JavaScript.

[SLG64]

I gave up on decompiling lol.

[BenSFGamer]

That's alright. You did all you could do within you skill set with this task. You can coumd also use github copilot for help and to delegate.

@SLG64
I probably will make a decomp of it sometime, but not right now

(Only Ch 1 and 2 tho)

[SLG64]

Okey
