A texture slot whose content the CPU writes now follows another image at its address only when that image differs in swizzle alone or holds GPU-written content; Ocarina reuses freed glyph atlas memory for captions of another width, and following the older image drew the Basic Controls screen's "Target" with the wrong row length. Mesh-shader pipelines are built on the workers and recorded in pipeline-keys.bin (version 4 with the task stage; version 3 files are converted) instead of stopping the frame for 0.26-0.51 s. The ASTC decoder reuses one scratch buffer per upload command buffer, and CPU-provided textures up to 32 MiB are sub-allocated unless the driver requires dedicated memory, which takes the scene-load frame from about 1.25 s to 0.7 s. The feedback scan looks only at bound texture slots instead of the bindless pool arrays, per-draw knob lookups are cached and the texture address buckets grow to 65536, so Kokiri Forest's replay falls from about 16 to 7-9 ms a frame and the forest holds 60 fps. A float clear of zero on an integer image now clears instead of being skipped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
NX2navi
NX2navi is a static recompilation of The Legend of Zelda: Ocarina of Time (Nintendo Switch, 2023) into a native x86-64 application for Windows and Linux (docs/architecture.md).
Important
No game files are included. You need your own legally obtained copy of Ocarina of Time, dumped from your own console: the base game and the 1.1.0, 1.2.1 or 1.4.3 update. 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. The game is playable on Windows and Linux; visual bugs and crashes are still expected.
Report problems as issues, following CONTRIBUTING.md.
Features
- Native code, not emulation
- Game updates 1.1.0, 1.2.1 and 1.4.3; 1.2.1 and 1.4.3 saves carry over between them
- Takes NSP and XCI game files, and compressed NSZ and XCZ as they are: the setup unpacks them itself
- 60 fps by default; up to 144 fps or the monitor's refresh rate (experimental)
- Custom resolutions (1080p, 2k...), supersampling and AMD FSR 1 upscaling
- NVIDIA DLSS / DLAA on RTX GPUs: the setup downloads
nvngx_dlss.dllfrom NVIDIA's DLSS SDK repository (github.com/NVIDIA/DLSS, NVIDIA RTX SDK license) when it finds an RTX GPU; untick it in the setup to skip it - HDR10 output with peak, game and HUD brightness settings
- 16:10 (Steam Deck, handhelds), 3:2 (Surface, Framework), 21:9 and 32:9 (ultrawide) game resolutions, with the camera and the interface in that shape
- Anisotropic texture filtering up to 16x, for sharp ground into the distance
- In-game settings menu (F1) and performance overlay (F10)
- Discord Rich Presence ("Playing NX2navi" with the play time), off by default, own application id supported
- Setup and in-game menu in English, Russian, Brazilian Portuguese and Simplified Chinese
- Keyboard, mouse and gamepad with remapping, rumble and gyro
- Stereo or 5.1 surround sound output
- Xbox button prompts: LB, RB, LT, RT, Menu and View, and A, B, X and Y as labelled on the button to press, with either button layout
- Shaders prepared at install instead of during play
- Mods made for emulators: unpack a mod into the
modsfolder next tonx2navi.exe; switch and order them in the menu. RomFS mods, a mod manager's merged output and ExeFS code patches (.ips,.pchtxt) work; the game rebuilds itself for code patches (docs/mods.md) - Atmosphère cheats: put a cheat file into a mod and switch its cheats in the menu (docs/cheats.md)
Planned
- VRR
Installing
Windows
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 and VK_EXT_external_memory_host, about 36 GiB free during setup (20 GiB after).
- Download
NX2navi-Setup-<version>-windows.zipfrom Releases and unpack it. - Start
NX2navi-Setup.exe. If SmartScreen warns about an unsigned app, choose More info, then Run anyway. - Pick your game files, the language and an install folder, and press Start. The setup builds the game once. With an NVIDIA RTX GPU it also downloads NVIDIA DLSS, unless you untick Download NVIDIA DLSS; turn DLSS on in the menu (F1).
- Play
nx2navi.exefrom the install folder.
Linux
Requirements: as on Windows, plus Linux 6.7 or later and glibc 2.34 or later (Ubuntu 22.04, Debian 12, Fedora 35, SteamOS 3).
- Download
NX2navi-Setup-x86_64.AppImagefrom Releases, or build it (docs/installer.md, "Linux release"). - Make it executable (
chmod +x NX2navi-Setup-x86_64.AppImage) and start it. On a Steam Deck, do this in Desktop Mode. - Pick your game files, the language and an install folder, and press Start.
- Play
nx2navifrom the install folder.
To update, run a newer setup on the same folder; saves and settings are kept. Settings are in the in-game menu and in nx2navi.ini (nx2navi.ini.example lists every key). Controls: docs/controls.md.

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. Testers: docs/tester-guide.md.
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.
