Eglantine has a new experimental Nintendo Switch 2 emulation build for PC. The project published nx2 build 64 on October 31, 2026 at 10:23 UTC. Its release brings fresh downloadable files for testers on Windows and Linux, but does not establish that every Switch 2 game is now playable or that performance has universally improved.
The official build 64 release is the primary source for the date and available software. The developers describe an automated pre-release from their evolving nx2 branch, linked to commit b7575b0. The short release notes contain no detailed game-by-game list of fixes or performance benchmarks, making it important to separate the build itself from broader claims about Switch 2 emulation.
What does Eglantine build 64 actually provide?
The downloadable release offers a Windows package and a Linux AppImage. Windows users are instructed to extract the archive and start the graphical eglantine.exe program, or use the eden-cli.exe command-line executable. On Linux, the AppImage requires glibc 2.39 or later, according to the project. The maintainers list modern distributions, including Ubuntu 24.04, Fedora 40, Debian 13 and Arch Linux, as examples of environments with suitable libraries.
Build 64 is specifically a development snapshot rather than a polished consumer release. The team publishes experimental updates frequently, and the existence of a new number alone does not mean a previously broken game has been fixed. There are also no release-note figures establishing a definitive FPS gain over build 63.
The Eglantine README describes a free, open-source emulator based on Eden, Yuzu and Sudachi code. Its C++ development is focused on running software originally designed for Nintendo hardware on other systems. The repository also contains a user handbook and instructions for people examining or building the source.
Can Eglantine run Mario Kart World on PC?
This is the claim likely to interest most players. Eglantine's developers state that Mario Kart World can run at decent or full speed depending on a PC's specifications and configuration. They separately report variable results with Splatoon Raiders. Those statements come from the emulator team. They are not an independent benchmark of build 64, and they do not identify a universal minimum GPU, fixed driver configuration or guaranteed frame rate.
Coverage published on October 31 has pointed readers toward videos of the emulator in action. Such demonstrations can help show real progress, but they may capture a narrow set of conditions. A brief working race is not proof that every track, mode or lengthy session works without crashes. We have not performed our own controlled test of build 64.
Players should distinguish booting a game from getting into actual gameplay, then distinguish both from running consistently for hours. A project can reach the second milestone while still encountering rendering glitches, save issues or crashes. That distinction is particularly important for an emulator tackling a relatively recent console generation.
What do the public bug reports reveal?
Eglantine's public issue tracker includes useful counterexamples to the most optimistic performance claims. In issue #74, a tester describes a Mario Kart World mid-race crash in build 55, after more than twelve minutes, with Vulkan rendering on an NVIDIA-equipped Windows PC. Other reports on experimental builds mention freezes and graphics problems.
These older reports do not prove build 64 is affected by the same bugs. Equally, build 64's short automated changelog offers no evidence that those issues were definitely solved. A responsible compatibility verdict requires new, repeatable results tied to the precise emulator build, game update, GPU, driver and operating system.
For someone comparing real-world experiences, useful questions include whether a title reaches gameplay, whether its audio and graphics remain correct, whether menus and saves work, and whether performance holds up after a complete race or extended session. These are stronger measures than a single peak FPS number.
Which operating systems are supported?
The October 31 release explicitly provides downloadable instructions for Windows and Linux. Its Linux requirements are not trivial for every machine: glibc 2.39 or newer may require an operating-system upgrade on older distributions. The broader project README also discusses macOS as a target, but readers should check the actual assets available for build 64 before assuming an equivalent tested download exists for that platform.
If you want to follow development, use the project's official GitHub release page, read the handbook, and avoid unrelated websites promising effortless compatibility or bundled commercial games. Back up legitimate saves and configurations before moving between experimental versions.
The emulator repository itself is not a distribution service for copyrighted Switch 2 games. Running an emulator is distinct from obtaining game content, firmware or encryption keys, and software licensing does not authorize downloading material you do not have rights to use.
Why this build matters—and what remains unknown
The verified development today is straightforward: another public experimental build exists, with Windows and Linux packages and continued work toward Switch 2 game compatibility. Public development is valuable because players can trace releases, inspect issues and compare specific test conditions rather than relying entirely on short clips.
But several important facts remain open. The October 31 notes do not say which graphics faults build 64 fixes, do not establish a minimum hardware configuration for Mario Kart World, and do not offer a comprehensive compatibility database. Performance may vary substantially by title and PC setup.
For now, Eglantine is an active technical project rather than a guarantee of reliable Switch 2 gaming on any Windows or Linux computer. The most informative next milestone will be reproducible, full-session gameplay tests across more hardware, accompanied by specific fixes documented in the official release history.
