UI:

• Fix for updates not being autoloaded
  • Closes #379
• PlayerSelect applet (#537)
  • Allows you to play Minecraft Nintendo Switch Edition, and Diablo 3 with multiple local players.
    • Those are just the 2 games I know of that use this. There's probably others.
• Compatibility List Viewer
  • You can access this via Help > Open Compatibility List. You can search for games you're interested in, and it only shows the games you actually own by default.
  • This functionality has also been opened as a PR on ryujinx-mirror.
• Headless in Avalonia
  • There is no longer a dedicated headless/nogui build. It's now integrated directly into the standard Avalonia build.
  • This was done to reduce confusion on what file to download, while also still allowing the users who use headless to continue using it.
    • There's even the ability to inherit your main Ryujinx's config, input settings & last used emulated Switch profile!
  • You can access headless Ryujinx by invoking Ryujinx via the command line with the first argument being --no-gui or nogui. The following should then be your old Headless script content, additionally with --use-main-config for the config inheritance mentioned above.
• Play Time in the UI now caps out at showing hours. It shows seconds at the least. If less than a second it will act like it was never played.
• You can now click on the Title IDs of games in the UI and they will be copied to your clipboard.
• There is now a button in settings you can click which will resync the time in Ryujinx to match your system's.
  • Note that this is not an active setting, it just sets the time to the current time. It can still fall out of sync.
• Intel Mac Warning
  • On every boot, and only one time during that session, you will be warned that Intel Macs are not supported, if you are running Ryujinx on one.
• Discord RPC:
  • Added Goat Simulator 3 asset image

I18N:

• Russian translation update (#450)
• Entire Swedish translation (#446, #513)
• Ukrainian translation update (original: #488)
• Korean translation updates (#422, #465, #502)
• Norwegian translation updates (#418, #503, #538)
• French translation update (#415)
• Simplified Chinese translation updates (#440, #375)
• Italian translation update (#489)

Graphics:

• Experimental Metal Backend
  • The label "experimental" is not for show! More games don't work than do.
  • If you're on an ARM Mac and want to get the best out of Metal without trial & error, set the graphics backend to Auto.
  • Using Auto on a Mac will use Vulkan for most games, and use Metal on the games it's known to work better than Vulkan + MoltenVK in.
  • There is currently a known bug where shader translation from Vulkan to Metal will eventually freeze.
    • To alleviate this, you can simply keep trying. It does do some translations before it freezes.
    • You can also delete or move your Vulkan cache to another location to start fresh to avoid this issue entirely.
• Vulkan
  • Resolve Image Usage Validation Error (#296)

HLE:

• Stub IHidServer SetGestureOutputRanges (#524)
  • Lets the new Donkey Kong game, Donkey Kong Country Returns HD, boot.
• Throw a more descriptive error when the loaded processes doesn't contain a process with key matching _latestPid (likely missing Firmware).

Infra:

• Various NuGet package updates (#203)
• Update the mac release script to use LLVM 17 (#519)

Nerd Zone:

• Removed a lot of manual observable properties in many ViewModels and replaced them with the CommunityToolkit.Mvvm ObservableProperty autogenerated ones to reduce the size of the view model files.
• Use UnmanagedCallersOnly for ARMeilleure delegates.
• The repeated <Border>s in MainStatusBarView have been turned into a reusable Avalonia Control: MiniVerticalSeparator
• ConfigurationState migration is now defined in a map of version => migrator function; to reduce code duplication.
• DiscordIntegrationModule now changes the current playing game state based on when TitleIds.CurrentApplication changes; instead of directly being invoked when a change is needed.
• Removed Ryujinx.UI.Common: it existed because previously the project had 2 different UI layers you could use; GTK and Avalonia. We only support Avalonia now and will probably never support another framework.
• The logic for launching an applet, such as miiEdit, has been abstracted into a utility class called AppletMetadata.
