Azahar 2125.0 RC1 is released. An open-source 3DS emulator project based on Citra.

Azahar changelog:
libretro
Azahar is now available as libretro/RetroArch cores for various OS platforms. | @warmenhoven #1215 + other PRs
Below is a list of platforms with available cores in this initial release:
Linux (x86_64)
Windows (x86_64)
macOS (arm64)
macOS (x86_64)
Android (arm64)
iOS
tvOS
Other platforms and architectures may be added in subsequent releases.
It's important to note that, due to restrictions around the use of JIT compilation on the App Store, the iOS and tvOS have JIT forcefully disabled by default* on those platforms. Disabling JIT has a big impact on performance, so emulation speed may be below 100% on devices other than those which have been released relatively recently.
* For more information, read here: https://docs.libretro.com/guides/install-ios/#jit
When 2125.0 is fully released, the Azahar core will be available via the RetroArch core downloader and as a built-in core on iOS and tvOS.
All
Implemented a disk shader cache for the Vulkan renderer in the form of .vkch files. | @PabloMK7 #1725 #1748
These files keep track of compiled shaders so that there is no need to recompile them on subsequent application launches, which removes all stutter caused by shader compilation after the first playthrough of the application.
Cache files can also be copied between your own devices to benefit from the reduced stutter.
Added compatibility with NetPass by implementing NWM_SOC::GetMACAddress. | @PabloMK7 #1840
Requires "Enable required LLE modules for online features" to be enabled alongside the BOSS LLE module.
The BOSS LLE module has recently been observed to cause the HOME menu to stop opening correctly under certain conditions, so use with caution until we've investigated the issue.
Greatly reduced CPU usage of Azahar while using Artic Base. | @keynote #1789
Shader and pipeline compilation tasks are now handled by separate workers, improving parallelism and slightly reducing shader compilation stutter. | @PabloMK7 #1802
Re-added texture filtering functionality while using the Vulkan renderer. | @jbm11208 #1675
This feature was previously added in version 2124, but was subsequently removed in 2124.2 due to stability issues.
This iteration should address the issues present in the previous implementation.
Fixed an issue where, if a game with no cheats had its cheat list viewed or the game was launched, the cheats list for the previously loaded game would be erroneously used. | @Fs00 #1640
Minor fixes to local play for Luigi's Mansion 1 and Download Play applications. | @lannoene #1690
Minor optimization applied to the Vulkan renderer which slightly reduces its memory usage. | @PabloMK7 #1710
Very minor optimization for log message filtering, effective when a large number of LOG_DEBUG messages are produced in a short time-frame. | @PabloMK7 #1773
Implemented new "Integer Scaling" option. @DavidRGriswold #1400
Added a new "Layouts to Cycle" setting, which allows users to select which layouts are cycled by the Cycle Layout/Toggle Layout hotkey. | @DavidRGriswold #1430
Apply the selected texture filter to color surfaces, not just texture surfaces. | @PabloMK7 #1784
Major refactor of configuration backend for all platforms, improving maintainability | @OpenSauce04 #1762
This change is primarily a developer-facing one, but does somewhat affect end-users on Android by having the default config.ini file be dynamically generated and validated, meaning that keys which were missing in the default config file are now present. | @OpenSauce04 #1762
CECD LLE module is now enabled by the "Enable required LLE modules for online features" setting. | @PabloMK7 #1842
Download Play sessions can now be both connected to hosted without the DLP LLE module, meaning that Download Play is now fully operational with HLE only. | @lannoene #1741 #1828
Fix an issue where certain applications, such as Nintendo Video, would incorrectly think they were receiving SpotPass data. | @lannoene #1828
Added a debug option which allows toggling the console type specified in the console unique data between the Old and New 3DS types. | @PabloMK7 #1826
Addressed validation issues Vulkan renderer which could potentially have resulted in undefined behavior. | @PabloMK7 #1818
Fixed Nintendo Badge Arcade incorrectly displaying an "update data has been applied" message. | @PabloMK7 #1845
Version numbers have been moved to the end of the release files' filenames for easier readability. | @OpenSauce04 #1815
Implemented NAND RW, NAND RO, and NAND RO W archives, allowing the use of applications which utilize these archives. | @PabloMK7 #1861
Android
Added a new "Hotkey Enable" button bind. This button can be used in button combinations to activate hotkeys. | #1464
See the linked PR for a more detailed explanation.
Added new "Auto-Map Controller" button which functions similarly to its desktop equivalent. | @RJNY #1769
The drawer menu now always uses the layout appropriate for the current device orientation. | @DavidRGriswold #1473
Android (Vanilla)
Move to a new package ID, org.azahar_emu.azahar. | @OpenSauce04 #1874
The Google Play variant still uses the old package ID, meaning that these two variants now how separate package IDs.
Migrated to a more consistently effective method of determining removable storage paths. | @PabloMK7 #1863
Transition to using fully native file I/O for the Vanilla (non-GooglePlay) build variant. | @PabloMK7 @OpenSauce04 #1795
This results in extreme reductions of loading time compared to previous builds or the current Google Play build.
As an example, booting the HOME menu has been observed to drop from taking 30-45 seconds to now taking under 5 seconds.
As explained in previous patch notes, these improvements don't apply to the Google Play build due to restrictions put in place by Google via their Play Store app policies.
Desktop
Implemented a setting which allows a controller touchpad to be used to control the emulated 3DS touchscreen. | @DavidRGriswold #777
Fixed a rare issue where the emulator could attempt to pre-load custom textures even when they were disabled, resulting in a crash. | @coolguy1842 #1629
Fixed an issue where a small subset of setting tooltips wouldn't have any automatic line breaks as intended. | @OpenSauce04 #1718
Added new "Enable display refresh rate detection" debug setting. | @OpenSauce04 #1726
This setting is enabled by default, and disabling it prevents Azahar from attempting to detect the display's refresh rate when choosing its preferred Vulkan presentation mode. Disabling this setting can result in emulation slowdowns with certain displays, so it's recommended to leave it enabled unless you know what you're doing.
Fixed an issue which could cause Azahar to crash when resetting all settings to their default value. | @ChaseParate #1751
Removed all code relating to the old SDL2 frontend. | @OpenSauce04 #1756
This is not to be confused with the SDL2 functionality present in the Qt frontend.
This exclusively refers to the SDL2 emulation frontend, which has been disabled at build time by default for ages.
Improved update checker logic to prevent potential downgrades caused by hypothetical future release patterns. | @RedBlackAka #1749
Windows
Fixed camera emulation with a real camera not working as intended in the MSYS2 build. | @jbm11208 #1812
Fixed filesystem issues with some games due to minor file I/O emulation inaccuracies. | @PabloMK7 #1841
Fixed an issue where certain characters in an application name could become corrupted when creating a desktop shortcut. | @RedBlackAka
Explicitly tell AMD drivers to use the dedicated GPU by default if an integrated GPU is available. | @RedBlackAka #1783
macOS
Added a warning message when launching Azahar directly rather than from the .app bundle informing users of the proper way of launching the app. | @OpenSauce04 #1873
Fixed a possible UI freeze during game list population. | @TeamPuzel #1785
Technical
If certain features are disabled at compile-time in the desktop build, code related to those features is now more aggressively excluded. | @RedBlackAka #1630
Detection of CPUs using the FMA4 extension has been di...
