chrg6 8daedbd806 Redraw the in-game menu with the game's own interface textures, and bring in the launcher's save import and faster builds.

In-game menu: the settings window, its tabs, rows, buttons and cursor, the performance overlay and the Preparing
shaders box are drawn with the game's interface textures where the RomFS holds them (runtime/ui/menu_skin.cpp,
perf_panel.cpp; plain shapes until they are decoded). Restart joins Continue and Quit, each behind a confirmation;
VSync is an on/off switch; DLSS is listed only on NVIDIA GPUs; the menu sounds are quieter; Picture shape is gone and
the setting descriptions are shorter; edge cases of input, layout and fonts are fixed. tools/menu_preview.py draws the
menu without the game.

Launcher: Import Saves takes a save from the game folder's saves/ folder or one the player picks; downloads fall back
to Windows' own certificate check when Python's refuses a server; updates are faster; the title bar is drawn in the
window and Navi is every icon. tools/make_game.py builds with CLANG64's clang where the launcher installed it, packs
the RomFS beside the lift and the compile, takes a prebuilt runtime, and compiles the game's resources without cmd.exe,
so a user folder with a space in its name builds.

NX2navi build kit

This kit builds The Legend of Zelda: Ocarina of Time (Nintendo Switch 2, game version 1.1.1) as a native Windows program on your PC, from your own copy of the game. The kit contains no game code or data. Everything the build writes (ocarina.exe, the RomFS image, the shader cache, your saves) comes from your game: keep it to yourself.

The NX2navi launcher (NX2navi-Setup.exe, launcher.md) does everything below for you, the downloads included, and keeps the game up to date. This page is the same build by hand.

What you need

64-bit Windows 10 or 11, 16 GB of RAM, a Vulkan 1.3 graphics card with mesh shaders and a current driver (tested on NVIDIA).
Your own dump of the game as a .nup file (or its exefs and romfs folders), with the 1.1.1 update: program 0400486024DEC000, main build e0f3ccfa. Other versions are refused.
About 30 GB free on the disk you build to, besides the dump.

One-time setup (about 15 minutes)

Python 3.12 or later from python.org. Tick "Add python.exe to PATH" in the installer. Then, in a Command Prompt:
```
py -m pip install numpy lz4 zstandard zbic
```
zbic unpacks the game's compressed program files. It is a separate GPL-2.0 package you install yourself; the kit only calls it.

MSYS2 from msys2.org, installed to the default C:\msys64. Open MSYS2 UCRT64 from the Start menu and paste:

pacman -S --needed mingw-w64-ucrt-x86_64-clang mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-sdl3 mingw-w64-ucrt-x86_64-opus mingw-w64-ucrt-x86_64-libvpx mingw-w64-ucrt-x86_64-dav1d mingw-w64-ucrt-x86_64-zstd mingw-w64-ucrt-x86_64-vulkan-headers mingw-w64-ucrt-x86_64-vulkan-loader mingw-w64-ucrt-x86_64-vulkan-memory-allocator

Answer Y when it asks. If MSYS2 is somewhere other than C:\msys64, add --msys <folder>\ucrt64 to the build command.

Build (about 10 to 15 minutes, once)

Unpack this kit anywhere, open a Command Prompt in its folder and run:

py -I tools\make_game.py --nup "C:\path\to\your game.nup" --out "C:\Games\Ocarina"

With extracted folders instead, use --exefs "C:\path\exefs" --romfs "C:\path\romfs" in place of --nup. To only check that your dump is the right version, add --check (it builds nothing).

The build checks the version, unpacks the program files, packs the 26 GB RomFS image (every file is checked against the dump's own checksums) while it turns the game's code into C and compiles it (about 6 minutes on a 16-thread Ryzen 7; longer on fewer cores), then prepares every one of the game's shaders for your graphics card (about 5 more minutes), so the game does not stop to compile shaders while you play. The game it builds is for this PC's processor. You can use your PC meanwhile. If it stops, run the same command again: finished steps are skipped.

When it says finished, start C:\Games\Ocarina\ocarina.exe. You can delete C:\Games\Ocarina\build-cache (about 5 GB) afterwards.

Playing

F1 opens the settings menu. Settings are saved in nx2navi.ini beside the game; saves go to profile\.
Every shader was prepared during the build. After an update of your graphics driver, the next start shows "Preparing shaders" once while the driver rebuilds them. With a driver that has Vulkan's graphics pipeline library it lasts at most about 20 seconds once the shaders are translated, and the remaining pipelines are built in the background while you play.
Screen in the menu has Upscaling (DLSS on NVIDIA RTX cards, FSR 3.1 on any card), Frame generation (FSR 3.1; it needs DLSS or FSR 3.1 upscaling on), HDR (Native is the game's own HDR; turn HDR on in Windows first) and the resolution. Those marked "after restart" take effect when the game starts again.
DLSS needs nvngx_dlss.dll from NVIDIA beside ocarina.exe (the kit does not include it); FSR 3.1's amd_fidelityfx_vk.dll is copied there by the build.
Logs are in logs\. When reporting a problem, say where you were in the game and which graphics card you have, and attach logs\nx2navi.log. Never send game files.

If something goes wrong

Message	What to do
`not game version 1.1.1`	Install the 1.1.1 update and dump the game again
`the Python package ... is missing`	Run the `pip install` line above
`...\clang.exe is missing`	Run the `pacman` line above in MSYS2 UCRT64
`needs ... GB free`	Free space on the `--out` disk, or build to another one
The game opens and closes	Update your graphics driver, then send `logs\nx2navi.log`
