Cemu

Cemu is currently only available for 64-bit Windows, Linux & macOS devices. You can download the latest Cemu releases for Windows, Linux and Mac from the GitHub Releases. For Linux you can also find Cemu on flathub. The native macOS build is currently purely experimental and should not be considered stable or ready for issue-free gameplay. There are also known issues with degraded performance due to the use of MoltenVK and Rosetta for ARM Macs. We appreciate your patience while we improve Cemu for macOS. Issues with the emulator should be filed using GitHub Issues. The old bug tracker can be found at bugs.cemu.info and still contains relevant issues and feature suggestions. Pull requests are very welcome. For easier coordination you can visit the developer discussion channel on Discord or alternatively the Matrix Server. Before submitting a pull request, please read and follow our code style guidelines listed in CODING STYLE.md. If coding isn't your thing, testing games and making detailed bug reports or updating the (usually outdated) compatibility wiki is also appreciated! Questions about Cemu's software architecture can also be answered on Discord (or through the Matrix bridge). We ask that all code submitted is written and understood by a human. You can use AI for planning, designing, reviewing and for asking questions about the codebase, but the code itself needs to be written by you. As a small exception you can use intellisense-style AI code autocompletion for pure boilerplate code as long as it's only a small part of your submission. To further clarify, when we ask for "human written" that excludes letting an AI write the code and then paraphrasing it. In other words, we are asking for human effort. We have relatively low reviewing capacity and requiring human-written code increases the quality and trustworthyness of submitted pull requests. There are also general concerns with AI usage in emulation: LLMs tend to make up solutions that work on the surface but are generally not accurate in the emulation sense There is evidence that LLMs have been trained on leaked proprietary SDKs and we cannot verify the origin of the knowledge. This is especially a problem for core emulation logic Please keep these points in mind when contributing to Cemu. Contributions that do not follow this policy may be rejected.
