Eden v0.0.4-RC1 is released. Eden is the world's most popular open-source Nintendo Switch emulator, forked from the Yuzu emulator — started by former Citron developer Camille LaVey and the Eden team. It is written in C++ with portability in mind, and we actively maintain builds for Windows, Linux and Android.

Eden Changelog:
Critical
A bug fix in v0.0.4-rc1 related to improper handling of profiles may result in you losing save data if you're not careful. Read the following very carefully:
If your NAND directory is configured to be anywhere other than the default, there is a good chance you will receive a dialog about orphaned profiles. To solve this:
Take note of what profiles are orphaned
Backup ALL your save data
Find the largest and most recently-updated profile folder
Delete all profiles, but leave any that the dialog told you were VALID
Copy your "good" saves to the good profile (it should NOT be all zeroes)
If some of your saves are missing, try other old profile folders.
Universal
Full REV12/REV15 support, and HID support for new games and updates
Notably, this allows for many new updates like TotK 1.4.2, BotW 1.8.2, and others to run.
This also fixes controller-related bugs in some newer games.
Initial support for firmware 20.x
Some minor issues may still occur, especially in the Home Menu applet. Always keep a backup of a firmware dump from 19.0.1 or earlier just in case.
Notably, game icons may not show up in the home menu.
Fixed save/mod data loading from the Home Menu applet
Removed the NCA verification bypass
Games/updates that previously required NCA verification disabled will now work out of the box.
Reduced memory mapping latency on Linux and Android
Optimized texture pass during shader recompilation
Fixed FIFA FC26 launch
New window adaptation filters are available: Lanczos, Spline-1, Zero-Tangent, B-Spline, Mitchell, and MMPX
For more information, see the User handbook
Merged Dynarmic optimization passes into a single TU
Improved async shader building
Graphical glitches caused by this option, notably in Tears of the Kingdom, should be reduced.
Unstubbed process winding services
This fixes applets on firmware 20.x, alongside Bioshock Infinite.
Many settings have had their verbiage updated and clarity improved
Fixed audio glitches in Echoes of Wisdom
Improved CPU/GPU video decoding detection, and better error handling thereof
Fixed stutters/freezes during certain FMV scenes
Notably, this improves Super Mario Galaxy 1/2
1.25x resolution option
Fixed crashes caused by improper controller detection
Improved game decryption performance
This has been shown to significantly reduce startup times, especially with lots of mods installed.
On Android, some games now launch ~2x faster.
Translations for many languages have been dramatically improved and updated.
If you wish to translate, go to our Transifex page
Cheats can now be done without build IDs, like Ryujinx
Keep in mind that this will not allow for build ID matching, which may cause issues with game updates.
Reduced Dynarmic code bloat
Fixed BotW missing audio
Renderer
Improved Vulkan memory allocation
This should moderately increase R/W speed of Vulkan-allocated memory
VRAM usage now works properly on integrated graphics
Fixed crashes in Fire Emblem: Engage and others caused by MSAA handling
Improved the fast buffer binding path
This fixes some flickering in games such as Kirby Star Allies
Fixed some memory leaks present in the shader compiler
Present buffers are now properly flushed after CPU work is done on them
Improved Vulkan spec compliance
These may improve some graphical bugs on stock Android drivers, but are moreso done for code correctness
Shader read barriers
Ring Buffers
This primarily avoids conflicts between the CPU and GPU, and may improve performance
Fixed RAII, and removed the option for such
Faster uniform buffers
This mitigates some memory errors in TotK and other games
Improved renderer error messages
Improved some edge cases where games like Echoes of Wisdom would have undefined rendering behavior
Desktop
Data Manager
Shows how much space is taken up by several commonly-used directories
These directories can be cleared, imported, or exported, and are theoretically compatible with Android's import/export system.
Fixed "Open Save Data Location" putting you in the completely wrong folder
Due to the nature of this fix, profiles may now be mangled and incorrect. See the note at the top of the changelog for what to do.
Orphaned profiles finder
Save data that is not associated with a specific profile is considered "orphaned" as it is effectively inaccessible.
Ryujinx save data linking
This allows users to share save data for specific titles between Eden and Ryujinx.
This feature is still in testing, especially on Windows.
FFmpeg was updated to version 8.0
Fixed some weirdness with the web applet setting
Play Time editing
Fixed misalignments on certain combo boxes (e.g. audio device) on the default theme
The compatibility list is back (though shortened)
Fixed the "Link" option during migration on Windows
Android
Improved stock Qualcomm driver compatibility
This initial support also improves overall game support on 8 Elite devices.
Future releases will expand upon this.
Compact grid view option
Fixed some occasional crashes/bugs related to the EmuReady intent and overlay
The APK is now 16kb-aligned
Foreground notification service
This helps keep the app alive when switching to other activities
Individual buttons can now be scaled on the overlay
The overlay can now auto-hide when it hasn't been used for some time
Android versions as low as Android 7 are now supported
Note that your device still MUST support Vulkan 1.1, and should meet the minimum requirements for processing power.
Mouse/keyboard support
Per-game configuration import, export, and sharing
Added play time features from the Desktop frontend
Certain unneeded popups and warnings have been removed
Added the update checker from the Desktop frontend
(experimental) Amiibo support
Ability to filter logs to only include useful errors and warnings, rather than useless information
Internal
Compatibility improvements for *BSD, Solaris, macOS, HaikuOS, and many more
NetBSD and DragonFlyBSD are now partially supported
LTO has been improved to utilize IPO (interprocedural optimization), aka "whole-program" optimization rather than individual library optimization
Windows can now be built with clang-cl and MSYS2/MinGW64
MinGW is not on CI yet, but early testing has shown it performs much better than MSVC
On UNIX-like systems, you can now build without any bundled dependencies at all
Our docs have been completely refactored, including a new User handbook
MbedTLS 3 is now supported
Debian 12, 13, and Ubuntu 24.04 are now fully supported
Even saner build identification
All assets have been optimized to take up less space
Many old, subpar reimplementations of Boost/stdlib functionalities were removed
As a consequence, *BSD support has been improved, and many deadlocks/weird bugs have been fixed on other platforms.
aarch64 is now fully supported for Linux, macOS, and Windows, though all three are experimental
Qt versions from 6.4.2 to 6.10 are now fully supported
Earlier versions are entirely untested, and Qt 5 is fully out-of-support.
Support for building with CCache has been improved
Windows 8.1 is now supported
Note that your device still MUST support Vulkan 1.1 or OpenGL 4.6
Builds
Several new builds are available. Builds marked as "standard" are the normal builds without PGO or similar.
Linux/clang
Clang theoretically provides better optimizations than GCC at the cost of potential instability. Thus, these builds should perform better but may have an additional glitch or two.
Windows/clang
Same deal as Linux, though it's still unfortunately limited by the MSVC backend's horrific optimization.
Linux/PGO
PGO (profile-guided optimization) uses data from prior compilations to determine the "hotspots" found within the codebase. Using these hotspots, it can allocate more resources towards these heavily-used areas, and thus generally see improved performance to the tune of ~10-50%, depending on the specific game, hardware, and platform.
Windows/PGO
Same deal as Linux, though it may be more unstable as PGO is tested much more frequently on Linux.
macOS
macOS still has significant graphical/performance issues and will likely crash A LOT.
Debian 12/13/Ubuntu 24.04
These are prebuilt .deb files for Ubuntu 24.04 and Debian 12/13 (Bookworm/Trixie), for both amd64 and aarch64. While experimental, they should provide better system integration than the AppImage, at the cost of not bundling the latest MESA drivers.
TLDR
So... you scrolled down here and ignored us telling you multiple times to thoroughly read the changelog. What do you need to know?
New updates for games, including TotK 1.4.2 and BotW 1.8.2, now work, alongside UltraCam and other mods for these updates
Firmware 20.x is now supported, though some features of the home menu may not work as expected.
If you get a scary popup saying orphaned profiles were found, backup ALL your save data, then delete all but the most recently updated/most populated profile folders.
Read the top of the changelog for more info.
As per usual, graphical bugs and glitches have been reduced, performance was increased, etc.
Some improvements to Legends: Z-A are present, but expect flickering and vertex explosions.
There are lots of new features, which you'll know about if you read the changelog ;)
