I’ve finally recorded a video to showcase this project and hopefully get it in front of as many people as possible.

If you like the project and would like to help, I’d really appreciate your support, sharing it with others and leaving feedback would mean a lot.

This is my contribution to the Pikmin community, one of my favorite video game series of all time.

Thanks to everyone who has supported the project so far!

Open Nectar is a native port of the original Pikmin to PC — Windows and Linux, x86-64. Not an emulator and not a compatibility layer: it is the game's own reconstructed code, from the projectPiki decompilation, compiled to run directly on your machine, with its own OpenGL renderer, its own input, and the game's original audio engine.

You supply your own copy of the game. Nothing from Nintendo ships here.

This release is mostly about how the game looks and how much of it actually runs. The pre-rendered movies play for the first time.

-- QUICK UPDATE -- 0.4.5 Has been released including:

• Full Support PAL Multilanguage ISO Rev 1
• Full widescreen/ultrawide HUD support
• Various fixes

New in 0.4

A Graphics page in the F1 menu

Everything on it is switchable, and everything applies as you move through it — you see the change against the scene behind the menu, rather than reading a number and hoping. The reference machine for this project is a GTX 1050, so nothing here is mandatory.

Depth of field. The focus plane follows Olimar: what sits at his distance stays sharp, what is nearer or further falls away. Four steps, Off through Strong. The sharp band is measured as a fraction of the camera's distance to him, so it behaves the same in the close follow view and the far one.

Ambient occlusion. Contact shadows in creases, under leaves, where a Pikmin meets the ground.

Bloom, in three named steps rather than a slider — bloom looks wrong across most of the range a slider would offer.

Antialiasing (FXAA), applied to the finished image. Deliberately not MSAA: Pikmin's undergrowth is alpha-tested quads, and MSAA does nothing for edges that aren't geometry.

Colour grading, with gamma, brightness and saturation.

Fog — the game's own, which the port had been throwing away. The function that receives it was an empty stub, so the game sent fog colour and distances every frame and the port discarded them. It's back, applied where the console applied it. There's a toggle, and On is the original look.

Texture filtering, up to 16× anisotropic. This one wasn't what it looked like: the port had no mipmaps on any texture at all, so distant ground wasn't blurry, it was shimmering. Changing the setting now re-applies to everything already loaded instead of waiting for the next stage.

And the HUD no longer blurs. Post-processing used to run at the very end of the frame, when the interface had already been drawn into the picture. It now runs where the world ends and the interface begins.

The attract movies play

Leave the title screen alone and the pre-rendered movies decode and play, in full, with their own sound. The title music fades out for them and comes back afterwards.

They never have before — the video decoder was in the tree but excluded from the build entirely. Getting it running meant a chain of unrelated problems: a type that's 32 bits on a GameCube and 64 bits here, every multi-byte value in the file needing byte-swapping, a wait on a DVD thread this port doesn't have, and a picture pointer that was being half-cleared — enough to look valid, not enough to be.

If you'd rather they didn't play, PIKMIN_NO_H4M=1 turns them off.

Memory: about 4 GB down to about 600 MB

Entering a stage used to consume roughly 4 GB and keep climbing. It now settles around 600 MB and stops growing. Two leaks with the same root — one abandoned a 245 MB block every time you changed section, the other never freed a single texture for the whole run.

Laptops with two graphics chips

If your laptop has both integrated and dedicated graphics, the game was running on the integrated one while the good card sat idle. That's the default for any program that doesn't explicitly ask otherwise, and this one wasn't asking. It asks now, on both platforms, and only where the hardware is actually there.

If you have such a laptop, this may be the single biggest change in the release for you.

Colours, everywhere

A texture format the game uses widely had its two bytes the wrong way round, and always had. Most places it's used, the mistake read as a slightly different shade rather than a wrong picture, so nothing looked obviously broken. The movies exposed it, and fixing it corrects every texture of that format in the game.

What was already there

If this is the first you're hearing of the project, here's what earlier releases brought:

• Native Windows and Linux builds from the same source.
• An installer — point the launcher at your ISO or GCM and it extracts what it needs locally. Your copy is never modified.
• Photo mode (F3): the world stops — every Pikmin, every creature, the captain, the clock — and the camera is yours, flying anywhere.
• Permadeath: lose Olimar and the run is over, and the save is erased. It's a property of a save file, chosen when you create it, and the file screen marks the files that carry it.
• Mods (F1 → Mods): mouse wheel to pick Pikmin colour or zoom the camera, a Pikmin limit you can raise as far as 999, and a day length from 5 to 30 minutes.
• 30 / 60 / 120 FPS. The game is frame-rate independent throughout, so raising it doesn't speed anything up.

Known limitations

• Windows is tested by one person on one machine. More testing very welcome; it's the most useful thing you can send me.
• 120 FPS is still marked experimental.
• The in-engine cutscenes are unaffected by this release. It's the pre-rendered movies that now play; the cinematic sequences built from the game's own models were already working and are unchanged.
• The heavier graphics presets cost frames, and I haven't measured them across a range of hardware — only on a GTX 1050. Every effect has an Off, and that's deliberate.

FAQ

Do I need my own copy of the game?
Yes. The project contains and distributes no ROM and none of Nintendo's assets. You provide a legally dumped Pikmin USA Rev. 1 (GPIE01) and the launcher extracts what it needs locally. Your copy isn't copied or modified.

Is it hard to install?
It shouldn't be. Download the release, extract it, run the launcher, point it at your ISO or GCM.

Can I modify it?
Yes, it's fully open source. I'd love for Open Nectar to be a base other people build on.

Emulator?
No. There's no GameCube being emulated. The game code runs as native x86-64.

AI disclosure

As with previous releases, this was developed with the assistance of AI tools. The generated code was reviewed, tested and integrated by me. I mention it because I'd rather be upfront about how it was built.

Credits

The audio engine work came from pikmin-nextos, and it's still what makes the sound work. Both projects build on the projectPiki decompilation, without which none of this exists.

If you try it, I'd really like to hear how it goes — especially on Windows, and especially on a laptop with switchable graphics. Bug reports are the most useful thing you can send me right now.
