- Profile 0100B04011742000 (update 16.0.2, RE Engine): KPKA PAK shaders (shader_split.py kpka_jobs), XCI base game in nx_extract and the NSP script, BIG_TEXT patch area in patch_nso.py. - Sparse virtual pool: a 4 KB page table (vpt_*) that the replay reads textures through, dirty tracking per mapped page, texture views from the first mapped level. - MultiDraw*IndirectCount with a CPU wait for the count; pending GPU writes indexed by page; bindless handles read from queued inline updates. - sbuf_ubo binding kind, integer vertex formats into float inputs, clears on textures that are not render targets. - Inline keyboard text, state and finished callback; ngc::ProfanityFilter host vtable. - Ryujinx BindlessElimination follows phi webs (218 MHR pixel shaders); dmsh_xlate_bin and dmsh_chain.lock updated; dmsh_chain.h and c1_full.tsv rebuilt for every Maxwell profile. - README: Monster Hunter Rise under being ported, gallery image, XCI base games, Ryujinx local fixes.
nxnative
Play your own Nintendo Switch games natively on iPhone and iPad. Bring your game (its NSP files) and your prod.keys; one script turns them into an IPA that you sideload.
It is not an emulator: the game's own code runs directly on the Apple chip, with Switch graphics rebuilt on Metal. Nothing from any game is in this repository, and the project is not affiliated with Nintendo or any game publisher.
Acknowledgements
This project is built on other people's work:
- d2r-mobile (MIT) developed this native-execution approach, for Diablo II: Resurrected. nxnative (first called smbw-mobile) started as a copy of its generic parts: the NSO rewriter, the host that stands in for Horizon, the NVN-on-Metal layer and the iOS app shell. Fixes go both ways.
- Ryujinx (MIT): its shader translator (
Ryujinx.Graphics.Shader,Ryujinx.CommonandSpv.Generator1.3.2, indm/third_party/ryujinxwith a few fixes listed in its README) turns the games' Maxwell shaders into SPIR-V. Its emulation of the kernel and system services is also a reference when the host's behaviour is in doubt. - Atmosphère: its kernel, mesosphère, is the reference for Horizon's synchronization semantics (address arbiter, condition variables).
- yuzu: Maxwell instruction encodings for the shader reference tool, and a cross-check for kernel behaviour.
- LibHac: reads NSPs and layers updates over the base game in
dm/tools/nx_extract. hactool did the first extractions. - SPIRV-Cross: SPIR-V to Metal Shading Language.
- deko3d (zlib): its texture layout size algorithm is ported in
dm/gfx/nvn/nvn_tex.c. - libvpx (VP9 movies), stb_vorbis (movie sound), libdeflate, the Vulkan headers and NVIDIA FLIP ship in
dm/third_partywith their licenses (list). - Capstone, lz4, fontTools and XcodeGen are used by the build.
Games
All of these are tested on an iPhone and playable:
| Game | IPA | Notes |
|---|---|---|
| Super Mario Bros. Wonder | ~4 GB | |
| Fire Emblem Engage | ~15 GB | Upgraded to 60 fps (30 fps on Switch) |
| Metroid Dread | ~5 GB | |
| 13 Sentinels: Aegis Rim | ~5 GB | |
| Super Mario 3D World + Bowser's Fury | ~3 GB | |
| The Legend of Zelda: Breath of the Wild | ~16 GB | Upgraded to 60 fps (30 fps on Switch) |
| The Legend of Zelda: Link's Awakening | ~6 GB | |
| Super Mario Odyssey | ~6 GB | |
| Hades | ~4 GB | |
| Hyrule Warriors: Age of Calamity | ~15 GB | |
| Fire Emblem: Three Houses | ~13 GB | Upgraded to 60 fps (30 fps on Switch) |
| Super Mario Galaxy | ~3 GB |
Being ported:
- The Legend of Zelda: Tears of the Kingdom (base game + update 1.4.3): runs on an iPhone into the opening cave; the frame rate is still being worked on.
- Monster Hunter Rise (base game + update 16.0.2): plays on the Mac from character creation into the opening in Kamura village; not yet tested on an iPhone.

Needs iOS / iPadOS 26 or later on an iPhone 15 Pro or newer (A17 Pro chip or later) or an iPad with an M1 chip or later: the games' textures are BC-compressed, and older iPhones can't read that format. Other games aren't supported yet. For them the script writes a survey and still tries its best to pack an IPA, guessing the game's settings; such an IPA may not start.
Pack an IPA
1. Get nxnative and its tools (once, on a Mac with Xcode and Homebrew):
git clone https://github.com/seedds/nxnative.git && cd nxnative
brew install xcodegen zstd spirv-cross
brew install --cask dotnet-sdk
python3 -m pip install lz4 capstone fonttools
2. Put one game's NSPs in a folder, base game (an NSP, or an XCI cartridge dump) and update (and any DLC):
~/Games/MarioWonder/
Super Mario Bros. Wonder [010015100B514000][v0].nsp
Super Mario Bros. Wonder [010015100B514800][v327680].nsp
3. Run the script:
python3 scripts/build_ipa_from_nsp.py ~/Games/MarioWonder -k ~/keys/prod.keys
The IPA appears in the same folder (here ~/Games/MarioWonder/SMBWMobile.ipa). The first build takes 30–60 minutes, later ones about 10. You need free disk space of about twice the NSPs' size plus 10 GB. Options such as -o (output path) and --app-name are listed by -h.
4. Install the IPA with your sideloading tool (AltStore, Sideloadly, LiveContainer, …). The app gets the game's name, icon and version (the update's version, for example 1.2.1 for Mario Wonder; the base game's when there is no update).
Play
Touch controls. Tap 2D / 3D at the top to switch layouts; the app remembers your choice. Wonder, Engage, Dread, 13 Sentinels and Link's Awakening start in 2D, the other games in 3D. In Super Mario Galaxy, touches outside the controls move the pointer. A connected game controller hides the touch controls and keeps every button.
- Game language is English by default. For Chinese, add the line
DM_LANG=zh-HanstoDocuments/env.txt. - Saves and logs are in the Files app, under the app's name:
save/andlog.txt. When something goes wrong, sendlog.txt(the previous run islog.prev.txt). - Short stutters the first time a new scene appears are normal: the app compiles graphics for it once and remembers them for the next launch.
- Reinstalling: some sideloading tools give a reinstalled app a new data folder. Copy
save/andpso_user.tsvover from the old one to keep your progress. - Settings without rebuilding: put lines like
DM_OPMODE=0(handheld mode: lower resolution, higher frame rate) inDocuments/env.txt.
Known issues
- No amiibo and no online features.
- Fire Emblem Engage: after switching away from the app and back, some sounds may stay silent until you restart it.
- Fire Emblem: Three Houses: small square patches on the ground where decals land.
- Super Mario Galaxy: effects drawn as points or lines come out one pixel wide.
