# MinecraftLCE: an early-stage Minecraft: Nintendo Switch Edition decompilation > Decompiles Minecraft: Nintendo Switch Edition v1.0.17, a Legacy Console Edition release, into C++ that is compared function by function with the original executable using a patched Clang 4.0.1 and the open-ead Switch decompilation tools. The README explains the choice of the Switch build for its matchable Clang toolchain and type information, with names ported from the symbol-bearing Wii U Edition. At the reviewed commit the function list marks about 11% of functions decompiled, most of them matching; the result cannot run the game. - Type: Case study - Targets: Game - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-19 - Added to the catalog: 2026-10-28 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/minecraft-lce-switch-decomp-case/index.md) ## Requirements & limits - README describes a work-in-progress decompilation of Minecraft: Nintendo Switch Edition v1.0.17 that cannot be used to play the game. At the reviewed commit data/mcswitch_functions.csv lists 57,972 functions: 6,279 matching, 224 non-matching and 51,469 not yet decompiled, the 11.217% that a workflow writes into the GitHub description. Matched functions are checked individually; there is no whole-executable rebuild. - Supply the main NSO executable from your own Minecraft: Nintendo Switch Edition v1.0.17 update; the Wii U Edition’s Minecraft.Client.rpx (Patch 35, v560) is recommended only for porting symbols. README says these executables will never be provided in the repository and no game assets are included. - Documented for Linux or WSL (with macOS also intended): Python 3.6+, Ninja, CMake 3.13+, ccache, llvm-objdump, libncurses5, a Rust toolchain and the listed Python modules. tools/setup.py converts the executable, downloads Clang 4.0.1 from the LLVM releases and applies the committed libc++ patches; submodules supply open-ead’s nx-decomp-tools, nnheaders and musl and the stb image library, and lib/ vendors libpng and zlib. - tools/check compares compiled functions with the original and tools/common/progress.py summarises the function list. CI lints, compiles the project without the game and publishes progress counted from the committed function list, so matching status is project-reported. - No license file is present and GitHub detects none; Minecraft belongs to Microsoft and Mojang, and vendored libraries keep their own licenses. README says Microsoft-licensed Java Edition mappings cannot be used and notes that projects whose research was not clean-room have been taken down. ## Primary sources 1. 2. 3. 4. 5. 6. 7. 8. 9. ## More in Games - [Ocarina of Time: decompilation with MD5-checked ROM builds for 16 versions](https://awesomerea.org/resources/ocarina-of-time-decomp-case/index.md) · Case study - [Paper Mario: matching Nintendo 64 decompilation for four releases](https://awesomerea.org/resources/paper-mario-matching-decomp-case/index.md) · Case study - [Paper Mario: The Thousand-Year Door: an early matching GameCube decompilation](https://awesomerea.org/resources/paper-mario-ttyd-decomp-case/index.md) · Case study - [Perfect Dark: matching Nintendo 64 decompilation](https://awesomerea.org/resources/perfect-dark-matching-decomp-case/index.md) · Case study - [Petari: a matching Super Mario Galaxy decompilation](https://awesomerea.org/resources/petari-smg-decomp-case/index.md) · Case study - [Phantom Hourglass: an early-stage matching Nintendo DS decompilation](https://awesomerea.org/resources/phantom-hourglass-ds-decomp-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
