After having been decompiled back in July, the source code for Super Mario 64 has been completely reverse-engineered, and is now publicly available. Available on GitHub is a full decompilation of the beloved 3D platformer, Super Mario 64. The decompilation works for the NTSC-U and NTSC-J builds of the game, with (E) ROM support coming soon. To keep things legal, you will need to provide your own copy of the game, in order to compile the data, with the exact process being detailed, below. If you've ever wanted to see some of the magic that went into creating such an iconic game, you can now finally see into all of the finer details.

Linux

1. For each version (jp/us/eu) that you want to build a ROM for, put an existing ROM at ./baserom.<version>.z64 for asset extraction.
   
   
2. Install the following packages:
   

Debian / Ubuntu

• git
• binutils-mips-linux-gnu / mips64-elf (>= 2.27)
• python3 (>= 3.7)
• build-essential
• pkg-config
• zlib1g-dev
• libaudiofile-dev

Arch Linux

• base-devel
• python
• audiofile
• mips64-elf-binutils (AUR)
• qemu-irix-git (AUR)

1. Install qemu-irix

3.a Options: 1. Clone https://github.com/n64decomp/qemu-irix to somewhere and follow its install instructions in the README. 2. Optionally, grab the prebuilt qemu-irix from the Releases section. 3. (Arch) Use AUR package qemu-irix-git

3.b (For options 1 or 2), copy executable qemu-irix from irix-linux-user to somewhere convenient with a relatively short path.

mkdir -p /opt/qemu-irix/bin
cp irix-linux-user/qemu-irix /opt/qemu-irix/bin

3.c Define QEMU_IRIX environment variable in your ~/.bashrc to point to this qemu-irix executable.

export QEMU_IRIX=/opt/qemu-irix/bin/qemu-irix

1. Run make to build the ROM (defaults to us version). Make sure your path to the repo is not too long or else this process will error, as the emulated IDO compiler cannot handle paths longer than 255 characters. Build examples:

make VERSION=jp -j4 # build (J) version instead with 4 jobs
make VERSION=eu COMPARE=0 # non-matching EU version still WIP

Windows
For Windows, install WSL and a distro of your choice and follow the Linux guide.

I would prefered Zelda OoT(and MM) source code, imagine that on a DS or better... on a Switch xDD

 

[wolf-snake]

You mean modern modern? All right!, here we go!

God that actually looks like souless crap.

 

[_DrBecks_]

We need Mario Party decompiled, so we could merge the best minigames of Mario Party 2 and 3 into 1

 

[Essasetic]

I am actually quite excited to see how developers will use this.

Maybe if someone makes an RTX mod I'll probably get an RTX GPU :^)

 

[Voyambar]

The heck? This is shocking news

Suprised you haven't heard about it since its been on the front page for the bulk of the day :shrek:

The game was released incomplete and buggy as hell to compete with Crash Bandicot. The DS port is actually better and you can actually beat it without using the touchscreen on the levels.

In fact while is nicer to play the game on a big screen, I beat the DS game three times from zero, while the Nintendo 64 version was just played until I beat Bowser and I didn't even care to get all the Stars.

Your crazy, wall jumps and movrment in general is way more fullfilling in the original. DS was good for multiplayer, portability, and a few game modes and characters but the core gameplay just feels right on the n64

Incomplete and buggy?

I played this game nonstop as a kid on the N64 and never experienced any game breaking or even significant bugs

Honestly this game was way more polished than most modern games

catch was/islow down. But most n64 games suffered it

Ocarina of Time 3D and Majora's Mask 3D.

Tell that to TV Tropes then.

Simpleflips intensifies

Fixed that for you.

 

[MAXLEMPIRA]

Ocarina of Time 3D and Majora's Mask 3D.

I would like to play it on DS for some reason... and in Switch... it would be totally HD models, textures and visual effects

 

[TheZander]

What will people be able to DOOM this into and play?

 

[Sheimi]

Maybe we can finally understand how the upward glitch works in Tick Tock Clock

You can reference the decompiled code for Super Mario 64, plus the compiled version, and compare the functions to those in other first-party N64 games.

You can then use the same symbols from Super Mario 64 for functions that serve the same purpose.

Games I'm going to do this with:

Super Mario 64 (Disk Version)
Mario Kart 64 (this one most closely resembles Super Mario 64's code base I've found)
F-Zero X
Ocarina of Time (NOT the debug version that everyone uses. I don't want bug fixes or bloat from the debug functions.)
Majora's Mask (NOT the debug version that everyone uses. I don't want bug fixes or bloat from the debug functions.)

Since this has the Super Mario 64 engine also, it shouldn't be to hard now to get to work on Zelda Ocarina of Time, Banjo and Kazooie etc. Now those would be great additions/addons for this source as extra's.

 

[Captain_N]

so how is this not copyrighted code. not that i care but yall go crazy when one tool is posted with nintendos code in it. this is the entire game.....

That's just what I though... I mean. both games were coded for N64 and by Nintendo... so, the code must be similar. Some changes here and there

Guess what else you can use? Diaphora

I can already see Nintendo fuming their asses out for not being able to do jackshit about this with DMCA's

explain why they cant because Mario's IP is still copyrighted hell NES games are still copyrighted and are still protected by that shitty law (F.U. G.W.)
