Short answer
Yes, the 3DS Ocarina of Time 3D now runs natively on PC, unofficially, through TriAevum: Echoes of Time by coccofresco, an ahead-of-time recompilation. It runs on Windows and Linux with a Vulkan renderer, a single-screen interface and 60/90 fps interpolation. Every build so far is a pre-release: the latest is v0.8.0-beta.1.2 (22 October 2026). You need your own decrypted ROM. It is not the N64 port Ship of Harkinian.
The Legend of Zelda: Ocarina of Time 3D is Grezzo’s 2011 Nintendo 3DS remake of the 1998 Nintendo 64 game, and it has only ever been sold for 3DS. coccofresco created the TriAevum repository on 7 September 2026 and published the first Windows build, v0.6.0-alpha.1, the same day. “Echoes of Time” is the name of its Ocarina of Time 3D project; the program files still say TriAevum. The repository had about 530 GitHub stars on 21 October 2026. We couldn’t find any press coverage of it yet.

What it is
- An AOT recompilation of the 3DS game: the game’s code is translated ahead of time into a native program, in the spirit of the Xbox 360 recompilation projects, per the README. A setup tool called Forge prepares everything from your ROM on first run.
- A new renderer: graphics run on NVIDIA’s NRI library over Vulkan, with optional cel shading and outlines, ambient occlusion, reflections, shadows, anti-aliasing, real widescreen, an adjustable field of view and a lot of procedural grass.
- One screen instead of two: the 3DS’s second screen is gone. The HUD and menus reimplement the fan mod TopScreen, now called SingleScreen, by rlgcarrot (M-1), which the README thanks first.
- Made with AI: the README says the TriAevum-specific work is entirely AI-assisted under human direction, and jokingly calls it “concentrated AI slop”. It also credits Azahar, Ship of Harkinian and libultraship as donor projects.
How it differs from Ship of Harkinian
| TriAevum: Echoes of Time | Ship of Harkinian | |
|---|---|---|
| Game | Ocarina of Time 3D (3DS, 2011) | Ocarina of Time (N64, 1998; GameCube versions too) |
| Method | Ahead-of-time recompilation of 3DS code | Fan decompilation compiled for PC |
| Platforms | Windows, Linux | Windows, macOS, Linux / Steam Deck |
| Stage | Beta pre-release since October 2026 | Stable releases since March 2022 |
| Your files | Decrypted 3DS ROM (.3ds or .cci) | N64 or GameCube ROM |
If you want the 3DS remake’s updated models and layout, this is the project. If you want the original game with years of polish, a randomizer and mods, Ship of Harkinian is the mature choice.
Current status
| State | Beta pre-release; “still untested in the wild”, per the latest release notes |
| Latest build | v0.8.0-beta.1.2, 22 October 2026 |
| First build | v0.6.0-alpha.1, 7 September 2026 (Windows only) |
| Withdrawn | v0.6.0-alpha.3 and alpha.3b (18 September 2026), marked broken; downloads removed |
| Open issues | 87 on 21 October 2026 |
| Licence | GPL-3.0-or-later for TriAevum’s own code; third-party parts keep their own licences |
What the README and the beta notes list:
- 60/90 fps visual interpolation of the original 30 Hz game; gameplay speed is unchanged;
- custom textures compatible with Azahar texture packs, and texture dumping;
- a free gameplay camera, keyboard, mouse and controller input;
- settings profiles, save states, and F1 for settings or F2 to toggle the added effects.
Known problems: the README says gameplay testing covers only the early parts of the game, and the USA version was checked only through installation, the intro and file select. Beta 1.1 targets crashes on AMD Radeon cards during setup, but the developer says it is unverified on AMD hardware, and noise on Intel Arc under Linux is not confirmed fixed. Steam Deck has not been tested on real hardware. We didn’t play the game through ourselves.
What you need
- Your own decrypted Ocarina of Time 3D ROM, a European or US version, in
.3dsor.cciformat. Forge checks the contents, not the file name. We don’t explain how to obtain or decrypt game data. - Windows or Linux on a 64-bit x86 PC.
- A Vulkan-capable graphics card with current drivers. The added effects can be heavy; the README suggests turning them down to suit your GPU.
- No compiler or SDK.
How to install
From the official README, at a high level: download the Windows-x64 ZIP (not GitHub’s source-code archive) or the Linux AppImage from the project’s Releases page and extract or open it in a writable place. Run TriAevum Forge, select your ROM, wait for preparation, then choose Launch game. After that, start TriAevum.exe (or the AppImage) directly. On Steam Deck, the README says to prepare in Desktop Mode and add the AppImage as a non-Steam game.
Since beta 1.1, the two files from the SingleScreen 3.0 mod that TriAevum needs ship inside the package, with the mod author’s permission, so Forge no longer downloads them. An optional official SingleScreen 3.0 or 3.1 archive adds the HD interface. The README still describes the older download step. Back up your saves: they live in data/ next to the Windows program.
Other Ocarina of Time projects
- Ship of Harkinian: the established native PC port of the Nintendo 64 original, by Harbour Masters.
- SingleScreen / TopScreen: the 3DS mod by rlgcarrot whose one-screen layout TriAevum reimplements. On its own it is a mod for the 3DS game, not a PC port.
Is it legal and safe?
- TriAevum is an unofficial fan project, independent and not affiliated with or endorsed by Nintendo, per the README. It says no ROM or original game assets are included. Recent builds do include two files from the SingleScreen fan mod, used with permission; the rights to them stay with that mod’s author.
- Use only a game you own.
- Get it only from the official GitHub repository. Each release lists SHA-256 checksums for its downloads. Avoid the withdrawn alpha.3 builds.

FAQ
Is there an Ocarina of Time 3D PC port?
Not an official one. Since September 2026 there is an unofficial native version of the 3DS game for Windows and Linux, TriAevum (its Ocarina of Time 3D project is called Echoes of Time) by coccofresco. It is still a beta pre-release; the latest build is v0.8.0-beta.1.2 from 22 October 2026. You need your own copy of the game.
Is TriAevum the same as Ship of Harkinian?
No. Ship of Harkinian runs the original 1998 Nintendo 64 Ocarina of Time and is built from the fan decompilation. TriAevum runs Grezzo's 2011 Nintendo 3DS remake, Ocarina of Time 3D, and is an ahead-of-time recompilation of the 3DS game code. They need different game files and look different.
Is TriAevum an emulator?
No. It is an AOT (ahead-of-time) recompilation, so the 3DS game's code runs as a native PC program with a new Vulkan renderer. It does reuse parts of the Azahar 3DS emulator and Ship of Harkinian projects, which the README credits.
What do I need to run TriAevum?
Windows or Linux on a 64-bit x86 PC with a Vulkan-capable graphics card and current drivers, plus your own decrypted EUR or USA ROM of Ocarina of Time 3D in .3ds or .cci format. We don't explain how to get one.
Does TriAevum run at 60 fps?
It shows 60 or 90 frames per second through visual interpolation. The game itself still runs at its original 30 Hz, so gameplay speed and physics are unchanged.
Was TriAevum made with AI?
Yes. The README says development of the project's own code is entirely AI-assisted under human direction. The mature projects it builds on, such as Azahar, Ship of Harkinian and NVIDIA NRI, are not covered by that statement.
