Out of the blue, and without any kind of mention, a mostly complete decompilation project coded in C/C++ from the SNES classic, The Legend of Zelda: A Link to the Past, has emerged on GitHub under the MIT license.

The project was released around 9 days ago, on August 14th, and seems to be playable from start to end.
Right now the decompilation is compatible with Windows (compilable with Visual Studio) and Linux (using SDL2 and Python).
At the moment, only keyboard is supported for controls, but those interested in contributing can do so through GitHub.

As with other decompilation projects, the repository doesn't include any of the original game's assets.
The project requires you to previously own and provide your own A Link to the Past ROM to extract all of the game's assets and begin the compilation afterwards.

Oh heck this is actually awesome!
I wonder what kind of stuff could be made out of it now
Mainly interested by the maps creation, the music engine, and actors/sprites management

Now this is cool. I stream this game a *lot*, so excited to see what fun will come from this.

I'm really interested in the map stuff more than anything.
I am currently making a disassembly to make A Link to the Past Redux open source, and the only problem I had is the map stuff doesn't seem to be keen on working with FastROM. That's where I hit a wall.

All in all, it's nice to see all these great games becoming open source and available in multiple platforms.

Wow that's not a decompilation, it's a reimplementation, like OpenMW is for Morrowind. Also:

Additionally, it can be configured to also run the original machine code side by side. Then the RAM state is compared after each frame, to verify that the C++ implementation is correct.

That's cool as hell! If it works, this can be verified to basically be a 1:1 recreation of the original.

You know nitnendo are absolutely seething.m about the source code to all their games being decompiled.

Oh I'm sure they're fuming out of their asses.
And the best part about all this is that they can't do jackshit about it, because they gamble losing on court due to precedented cases that Sony and other companies lost already lol

 

[Obveron]

Incredible! I can already taste the fan-made dungeons.

 

[Lostbhoy]

This is cool!! I'm interested in some sort hd retexture or something to make it look a bit modern.

There's already a Pull Request for adding basic Gamepad Support

 

[Robika]

Vita version pls!

 

[JeffRuLz]

It would be cool to see it running in widescreen on hacked consoles. Bsnes-hd is too demanding for older systems.

Vita version pls!

This should be really straightforward since it's just using SDL. Although, it would be a pain in the ass to install/distribute legally since it requires a ROM to build. People would need to compile it themselves, which doesn't seem worth the effort because if you have the ROM you can just run that through retroarch lol.

Maybe if it's refactored in a way to load the ROM at runtime it would make sense. That way people can just install the VPK and will have to put their legally obtained ROM onto their memory card. No need to build it manually.

Neat. I gave this a quick build and quickly did the out of bounds to the Triforce room for a quick laugh.

 

[TraderPatTX]

ALTTP is easily one of my favorite Zelda games. I'm pretty sure I got it for Christmas back in '92. Looking forward to see what comes of this project.

Should be easy enough to make a tool that can compile the code and all the user has to do is put in their own ROM.
That's how the other decomp projects do it for installers and such, Ship of Harkinian handles it this way.

Awesome, can't wait to see native ports on other platforms and easier mod support.

 

[SuperDan]

Super Widescreen Bsnes Please

 

[Lazyt]

never played this game so maybe its already time?

 

[linuxares]

So many decompilation. I wonder how many of them are just Ghidra dumps...
