Azahar 2123 RC 1 is released. An open-source 3DS emulator project based on Citra.

Azahar changelog:
All
Added ROM compression functionality. | @PabloMK7 #1208 #1249
Support for the following new formats have been added: .zcia, .zcci, .z3dsx, .zcxi.
ROMs can be compressed in Azahar using Tools --> Compress ROM File… on desktop.
Fixed a memory leak in the AAC decoder. | @QidiWang #1167
Fixed an issue where display refresh rates below ~60hz would cause emulation speed to be slower than intended when vsync was enabled. | @OpenSauce04 #1193, @kylon #1248
Different 3DS applications now have separate Vulkan pipeline caches. | @PabloMK7 #1118
Previously, all Vulkan pipeline caches were stored in a single large file which was shared between all 3DS applications.
Fixed LCD colour fill functionality. | @PabloMK7 #1198
Before being fixed, this could cause applications which fill the screen with a certain colour to be black or display garbage.
When using the OpenGL renderer, if a shader fails to link, the emulator will now experience graphical anomalies and produce logs rather than crashing. | @PabloMK7 #1200
Fixed some dead links left over from Citra. | @RedBlackAka #1250
Android
Implemented secondary screen support for wired and wireless displays (Chromecast, Miracast). | @DavidRGriswold #617
By default, this functionality is disabled, and must be enabled by setting Settings --> Layout --> Secondary Display Screen Layout to an option other that System Default (mirror).
Added button sliding behaviour configuration to the Overlay Options menu. | @toksn #884
Implemented play time tracking. | Kleidis, @rtiangha #813
MacOS
Fixed an issue where the Artic Controller feature wouldn't work correctly on MacOS. | @AlexMolina08 #1263
Fixed an issue where, on recent MacOS versions, enabling the OS’s low power mode would result in many games being limited to 50% emulation speed when vsync was enabled. | @OpenSauce04 #1193 #1262
Added individual x86_64 and ARM64 binaries to releases alongside the existing universal download | @RedBlackAka #1138
Desktop
Fixed horizontal centering being incorrect when using the single window or separate window layouts while fullscreened. | @DavidRGriswold #1211
Windows
Minor adjustments to the Windows installer. | @RedBlackAka #1234
Technical
Set correct stop flag in GSP. | @kynex7510 #1199
Fix irq request register behaviour. | @PabloMK7 #1216
This change and the previous one were noted to not affect 3DS applications at all in theory, instead being more of a correctness thing.
Fixed compilation failing when building using GCC 13 or earlier. | @OpenSauce04 #1221
Fixed a build error when using the USE_SYSTEM_GLSLANG CMake option. | @OpenSauce04 #1281, #1284
Added a new CMake option USE_SYSTEM_SPIRV_HEADERS. | @OpenSauce04 #1281, #1284
Removed use of deprecated boost class and moved to a functionally identical alternative. | @qr243vbi #1126
Upgraded Vulkan-related dependencies to match Vulkan SDK 14.313.0. | @OpenSauce04 #1225
Fixed the SDL frontend failing to compile due to the use of a removed function. | @OpenSauce04 #1190
The SDL frontend still doesn’t work properly, and remains disabled by default at compile time.
Various minor changes to the Azahar installer on Windows.
Amended CMakeLists to help certain environments to find required Qt dependencies. | @qr243vbi #1165
Upgraded Android Gradle Plugin to 8.11.1 | @OpenSauce04 #1256
