Since C++ code makes heavy use of inline functions and zero-cost abstractions that disappear in compiled code, contributors have a lot more leeway when it comes to organizing files and adding abstractions.

The result is that the codebase looks a lot more like a regular software project than a decompilation codebase. Libraries are not treated as being part of the game code, but as external dependencies. Instead of trying to match the entire executable, each function is matched individually and source code is organized in whichever way makes the most sense. Given the impossibility of automatically splitting the assembly and generating a matching binary (as is done in many other decomp projects), the sheer size of the main executable and the usage of many software libraries, this project takes a somewhat experimental approach to matching decompilation.īecause meaningfully splitting the code is not feasible, the built executable currently only contains functions that have been decompiled and no effort is being made to put functions and data at the correct addresses. Thanks to Clang, this is easier than one would expect. This process makes functional correctness extremely easy to verify since the assembly can simply be compared against the original executable.
Matching decompilation goes one step further and produces original source code that compiles to the exact same assembly. Frequently Asked Questions What is (matching) decompilation?ĭecompiling is the process of turning the game's compiled code back into equivalent, readable C++ source code. Any other statically linked library, except:Įxcluded libraries will not be fully decompiled but may be partly re-implemented or decompiled, and (reverse-engineered) headers will still be provided so that the rest of the codebase can still use those libraries.Framework/engine code ( KingSystem / ksys:: namespace).Actual game code ( Game / uking:: namespace).The RomFS and the SDK libraries are out of the scope of this project. This project only concerns the main executable which contains all the game code and statically linked libraries. It will help with understanding and reverse engineering the game even in its incomplete state, but it will not help with playing BotW or porting the game to other platforms, which is explicitly a non-goal. The goal of this project is to better understand game internals, aid with glitch hunting and document existing knowledge in a permanent, unambiguous form which helps further reverse engineer the game.Ĭonsidering the large size of the executable (~40MB), it is not expected to reach 100% progress within a reasonable timeframe.Īs a result, the project is unlikely to produce a working executable in the near future. This repository does not contain game assets or RomFS content and cannot be used to play Breath of the Wild.
The defense here is fair use and that you are not doing any financial harm to the publisher, but you are still taking a risk playing any game with an emulator.This is an experimental, WIP decompilation of The Legend of Zelda: Breath of the Wild v1.5.0 (Switch). Such emulators have the potential to significantly damage a worldwide entertainment software industry which generates over $15 billion annually and tens of thousands of jobs.”Īnd it is certainly illegal for you to obtain a copy of The Legend of Zelda: Breath of the Wild for CEMU over the internet without owning a copy already for Wii U. But, as always, the answer about whether it is legal for you to take your legitimately purchased copy of Zelda and rip it to a computer to play on an emulator is in gray area. “As is the case with any business or industry, when its products become available for free, the revenue stream supporting that industry is threatened. “The introduction of emulators created to play illegally copied Nintendo software represents the greatest threat to date to the intellectual property rights of video game developers,” the company explained. Publisher Nintendo is not OK with emulation, and it has a standing comment on the matter on its corporate website.
