Ocarina's NVN2 compute programs reach more than 16 buffers through their pushed pointers and pointer tables; past the 16th the translator found no slot, dropped the store, and its loop then read the next node of a node it had just removed, so every later global access in the block stayed global and the whole program failed with "Invalid storage kind GlobalMemory". Ten compute programs of Kokiri Forest were skipped on every dispatch and retried on every one, which also cost 10-25 ms frames. Now one program still fails (an Ampere MATCH instruction the lowering does not handle). NX2NAVI_XLATE_KEEP=2 keeps every translated job with its code for running the translator by hand.

Ocarina Recomp
Ocarina Recomp is a static recompilation of The Legend of Zelda: Ocarina of Time for Nintendo Switch 2 (game version 1.1.1) into a native x86-64 application for Windows, with a Vulkan renderer (docs/architecture.md).
Important
No game files are included. You need your own legally obtained copy of the game, dumped from your own console. Instructions for obtaining those files will not be provided.
The game is built from your files on your machine, so the result contains the game. It is for your own use. Do not share it.
Status
Early development. Kokiri Forest and the areas around it play at 60 fps and above; visual bugs and crashes are still expected.
Screenshots
Report problems as issues, following CONTRIBUTING.md.
Features
- Native code, not emulation
- 60 fps by default, or a limit of 30 to 240 fps, the display's refresh rate or unlimited
- Native widescreen and ultrawide (the window's shape, 21:9 or 32:9) with the HUD, menus and movies kept 16:9
- AMD FSR 1 or bilinear scaling to the window, with a sharpness setting; black bars or stretch
- In-game settings menu (F1, or Minus and Plus together on a gamepad) and performance overlay (F10)
- Keyboard, mouse and gamepads with remapping, Nintendo or Xbox button layout, rumble and gyro; the game follows whichever connected gamepad you press
- Stereo or 5.1 surround sound output
- Docked or handheld console mode
- Graphics cards with less than 20 GiB of video memory keep the game's textures compressed (BC3), about half the video memory at the same speed
Installing
The setup program for this game is not ready yet. docs/building.md describes building from
source. Settings are in the in-game menu and in nx2navi.ini (nx2navi.ini.example lists every
key). Controls: docs/controls.md.
Requirements: Windows 10 or later, an x86-64 CPU with SSE4.2 (AVX2/FMA machines get a faster build), a GPU with Vulkan
1.3, VK_EXT_external_memory_host and VK_EXT_mesh_shader.
License
The project's own code is under the MIT License; third-party code keeps its own license (THIRD_PARTY_NOTICES.md). The license grants nothing for Nintendo's game.

Building from source
docs/building.md lists the toolchain and the steps. Everything the build writes stays under
build\ and generated\, which git ignores; run tools/check_content.py before a commit.
Most of the code and documentation is written by AI coding agents (Claude Code) under the maintainer's direction; the maintainer plays every build and decides what is merged. AGENTS.md holds the rules they work under.
