Project overview

Selevet Eglantine is an unofficial build of Eglantine, a free and open-source Switch 2 emulator derived from Eden, Yuzu and Sudachi. The upstream project is written in C++ and targets Windows, Linux and macOS; this fork adds Zen 3-specific tuning, PGO, ThinLTO and faster GPU mapping updates, aimed at Mario Kart World performance. It is meant for people who want to experiment with this tuned configuration rather than use a stock emulator build; the changes relative to upstream are described in tuned/README.md.

The README states that Mario Kart World can run at decent or full speed depending on hardware and settings, and that Splatoon Raiders performance varies; no official compatibility list exists yet. A user handbook is available at docs/user/README.md.

Getting started

1. Get a build: the README points to the releases page for downloadable packages. Note that this link is hosted under a different account (Djihads80/Eglantine), not this repository. Check the provenance of those artifacts before running them.
2. If you prefer to build from source, follow the General Build Guide. The guide is the authoritative source for prerequisites and platform-specific steps; the README only links to it and does not reproduce the commands.
3. Configure and run: after installing or building, consult the user handbook for setup and configuration. The README does not document first-run steps such as firmware/key files or graphics backend selection, so those details must be taken from the handbook.

Usage constraints

• This is an unofficial, experimental fork; behavior and compatibility may differ from upstream Eglantine.
• The tuning targets Zen 3 CPUs, so gains are not expected on other microarchitectures, and the build may behave differently there.
• Compatibility claims are limited to Mario Kart World and Splatoon Raiders, with the former depending on your hardware and configuration.
• The project is licensed under GPLv3 or later (LICENSE.txt).
• The README says no donations are accepted and points contributors to Discord.

HotRepo's take

The repository appeared on HotRepo's new-project board for C++ on 2026-11-05, recording 50 stars gained over a roughly 22-hour window from 01:45 to 23:45 UTC that day. The hourly star samples collected show fairly steady growth from 100 to 193 between 2026-11-05 and 2026-11-06, though there is no GitHub all-language daily rank recorded. Interest is clearly concentrated in the niche of Switch 2 emulation and this fork's specific tuning target. Since the download and license links point to a different account's repository, readers should verify where builds actually come from before relying on them.
