Azahar 2127.0 Alpha 4 is released. An open-source 3DS emulator project based on Citra.

Azahar Changelog:
Android
Added per-application settings. | @DavidRGriswold #1856, #2698
Mimics the desktop behaviour of being able to configure emulated applications independently.
Can be accessed by long pressing the application from the application list.
Implemented the use of the ADPF API to hint the OS of CPU work bursts. | @PabloMK7 #2706
Improves performance on most Android devices, with a 15% performance boost observed on a Mali device.
Skip hidden dot files/folders when scanning for applications. | @wilu222 #2362
All
Reduced several audio, frame and input latency sources on all platforms. | @PabloMK7 #2700, #2706
Improves audio, frame and input latency by 1-2 frames in some cases.
Makes audio time stretching disabled by default.
Adds a setting to disable audio effects for the cubeb backend (Windows only).
The pull requests descriptions go into more detail on what exactly changed.
Added free camera support. | @PabloMK7 #2723
Uses the RPC server to submit free camera commands to the emulator from an external script.
A python script is provided in the dist folder that contains a global free camera implementation, controllable using a controller.
Due to the way the 3DS GPU works, per-application implementations are still the prefered way to do free camera.
Added configurable battery state. | @Wunkolo #2513, @PabloMK7 #2743, @DavidRGriswold #2738
Allows setting the emulated system battery to a fixed percentage and charging state, or use the host system battery state.
Makes the emulated notification LED blink red when the battery is critical.
Added a turbo (hold) hotkey. | @DavidRGriswold #1969
Not to be confused with the existing turbo hotkey, which is a toggle.
Fixed savestates not working with LLE modules enabled. | @PabloMK7 #2730
Added a visual warning that prompts users to reset the vulkan shader cache if the emulator crashes during cache loading. | @PabloMK7 #2709
Improved "disable right eye" setting heuristics. | @Davey-Hughes #2467
Fixes visual glitches in many applications with the setting enabled.
Fixed files opened with append mode starting on the wrong position. | @PabloMK7 #2707
Fixes OpenGL shader cache not working properly on Android vanilla and MacOS builds.
Fixed BOSS::GetNsDataHeaderInfo behaviour. | @PabloMK7 #2740
Fixes StreetPass Mii Plaza SpotPass puzzles being marked as invalid.
Fixed ADD PC instruction handling in thumb mode. | @PabloMK7 #2710
Fixes crashes when using the CPU interpreter with LLE modules enabled.
Fixed CPU core1 scheduler time limit value check. | @PabloMK7 #2711
Fixes 3DS Sound failing to start from the home menu.
Fixed APT::GetWirelessRebootInfo behaviour to match real hardware. | @PabloMK7 #2712
Fixes Star Fox 64 3D (Taiwan) failing to start.
Hardened stride aliasing validation on surface validation. | @Angelico2102 #2451
Fixes visual glitches in Inazuma Eleven GO Galaxy.
Fix DSP sleep behaviour to better match real hardware timings. | @PabloMK7 #2731
Fixes fatal errors on some applications (most notably New Super Mario Bros. 2) when launched from the home menu.
Fixed async upload of custom textures. | @nal532 #2688
Fixes custom texture related crashes and issues.
Fixed incorrect use of host timings on fs operations with deterministic mode. | @PabloMK7 #2732
Fixes a source of movie replay desync.
Desktop
Added optional on-screen software keyboard during emulation. | @rpnesseling #2185
Improves text input on handheld devices that are controller/touchscreen focused.
This option is disabled by default.
Fixed hat inputs not correctly detecting release and press state. | @DavidRGriswold #2457
Fixed some icons being missing in Azahar's application list since 2127.0 Alpha 3. | @OpenSauce04 #2686
Fixed path handling by converting paths to UTF-8 before using them with the raw C++ fs interface. | @PabloMK7 #2713
Fixes crashes with paths that contain non-ASCII characters.
Technical
Added savestate and input injection methods to the RPC server. | @PabloMK7 #2730, #2731
Added compressed ROM globs and fixed MIME icon name. | @999sian #2377
Updated cubeb dependency to a newer commit. | @PabloMK7 #2714
Added USE_SYSTEM_TEAKRA Cmake flag. | @qr243vbi #2615
Changed print to console behaviour when stdout is redirected. | @NimbusFox #2715
Provided a .png for AppImage building. | @PabloMK7 #2746
Fixed an issue with no-op optimization in the vulkan renderer caused by a typo. | @Lolothepro #2482
