The Legend of Zelda: Ocarina of Time 3D Recompilation

About

TriAevum is a native PC ahead-of-time recompilation of The Legend of Zelda: Ocarina of Time 3D, with a modern NRI/Vulkan renderer, a single-screen UI and customizable graphics. The author says most of the effort went into the renderer, aiming to push visuals further without losing the original look.

How it differs from the original

It adds cel/toon shading and outlines, ambient occlusion, optional reflections, shadows and anti-aliasing, real widescreen framing, configurable field of view and 60/90 FPS visual interpolation of the original 30 Hz game state.

Getting started

It requires Windows or Linux x64, a Vulkan-capable GPU and your own decrypted EUR or USA ROM in .cci or .3ds format. Download the release zip, run the Forge tool, select your ROM, then choose Launch game; no ROM or game assets are included.

Known issues & limitations

• The alpha.3 and alpha.3b builds are broken, withdrawn, and should not be used.
• This is an experimental alpha, not a fully tested port; gameplay testing covers only the early parts of the game.
• The USA adapter was checked through installation, the title intro, and file selection, but not a full playthrough.
• Steam Deck physical hardware and Gaming Mode have not yet been tested.
• Effects can be expensive, so adjust them to suit your GPU.
• Ray tracing is a wishlist item, not a feature of this release.
