RetroArch 1.9.1 – shines brightly on OpenDingux

Libretro Team

Written by jdgleaver

This is a followup article to our main release blog post, which can be read here.

Official support for OpenDingux devices such as the RG350M, RG280V and GCW-Zero was added last December; a full round-up of features and highlights can be found in the original announcement here. Version 1.9.1 represents the first stable release for this platform.

As an integrated member of the RetroArch family, the OpenDingux port benefits from all frontend development work – but a major addition for this release is a separate, optimised build for OpenDingux Beta (link here). This is an updated, modern firmware (compatible with many devices) which offers significantly improved performance. RetroArch is one of the first applications on OpenDingux Beta to enable configuration of the hardware IPU (Image Processing Unit), with menu-based control of aspect ratio/integer scaling and image filtering method (available on Beta releases after 16/03/2021). Users who prefer to remain on stable operating systems need not fear, however: RetroArch will always be optimised for both beta and stock firmwares.

Aside from RetroArch itself, expanding the library of available cores has been a major focus of this release. Launching initially with 20 hand-picked cores, a further seven have been added to the list:

  • Mr.Boom
  • O2EM (Magnavox Odyssey2 / Phillips Videopac+)
  • Potator (Watara Supervision)
  • ProSystem (Atari 7800)
  • ScummVM (Note: High resolution games unsupported)
  • Stella 2014 (Atari 2600)
  • TIC-80

All of these cores have excellent performance on OpenDingux devices (with the mild exception of TIC-80, which can be a demanding system on many platforms – yet a number of popular carts run full speed). It should also be noted that when building cores for OpenDingux, we don’t just hit compile and call it a day. This is a curated port, and care is taken to clean up code and add features wherever possible – and these additions improve the user experience on *all* platforms. For example:

O2EM

  • The model and region of the emulated console (Odyssey 2, Videopac+ G7400) can now be specified via core options
  • A volume control and optional low pass audio filter have been added, along with audio fixes/performance improvements
  • An ‘Interframe Blending’ option has been added, used to simulate CRT ghosting effects
  • A ‘Crop Overscan’ option has been added
  • Gamepad inputs can now be swapped (required for a number of games), and numeric keys have been mapped to gamepad buttons
  • The rendering of the virtual keyboard has been optimised, reducing performance overheads by 44%-63%
  • Save states have been fixed

Potator

  • This newly-added core was ported specifically for use on OpenDingux devices!

ProSystem

  • 16 bit colour depth support has been added for improved rendering performance
  • An optional low pass audio filter has been added, along with general audio quality improvements
  • A dual stick controller mode has been added for games such as Robotron: 2084

Stella 2014

  • 16 bit colour depth support has been added for improved rendering performance
  • An ‘Interframe Blending’ option has been added, used to simulate CRT ghosting effects and remove screen flicker
  • An optional low pass audio filter has been added
  • Full analog paddle support is now available

TIC-80

  • Comprehensive support for mouse input via gamepad has been added

And one more gift for OpenDingux users: the gpSP core now has a fully functional dynarec, courtesy of davidgf. This means full speed GBA emulation, with plenty of headroom for video filters, colour correction and inter-frame blending!

(gpSP has also seen many other fundamental improvements, too many to list here – further updates will be covered in a separate post)

RetroArch 1.9.1 released!

RetroArch back in action!

Today marks an important day for our project. We consider the migration to the new infrastructure to be almost 95% done. We have left the old infrastructure behind, it is done and dusted and a thing of the past.

From now on, you can expect periodic stable releases again for all platforms. Expect our project to be hitting on all cylinders from this point on!

One blog post is not enough to go through all the milestones that have been reached, so expect many followup blog posts in addition to this. In this blog post instead we will try our best to summarize most of the highlights.

What remains to be done:

  • Some cores will still need to be added (mainly cores that require compilation with CMake for iOS)
  • Windows binaries right now are still unsigned and not codesigned. We have ordered an Extended Validation code signing certificate which will allow our Windows binaries in the future to pass through SmartScreen with no issue. This will cost us a pretty penny each year but we consider the additional cost worth it for our users. We hope that by the time the next stable rolls out of the door, these binaries will all be signed, as will the nightlies.
  • Because of this, be aware that while installing RetroArch on Windows with the Installer, you might be greeted by a SmartScreen filter that the application is unsafe. You can safely ignore this.

Here’s some additional new platform releases since this new stable:

  • For the first time ever, we have rolling nightlies and stables for iOS (ARM64/Aarch64), tvOS, and macOS.
  • For the first time ever, we have an Apple Silicon/Mac M1-compatible build of RetroArch. Download the Universal Metal build if you intend to use RetroArch on one of these new Macs.
  • For the first time ever, we also have a new backwards compatible version of RetroArch for iOS 9 users. iOS users can choose between an iOS 9 version (which is 32bit ARM only) and an iOS 11 version (which is 64bit ARM only). We intend to follow this up in the near future with an iOS 6 version. We here at RetroArch believe in the promise of backwards compatibility and we always intend RetroArch to be an omnipresent platform that can be run on any device you want. We love the ability of users being able to turn their obsolete iDevices into capable little RetroArch handheld machines.
  • For the first time, macOS stables and nightlies are codesigned and notarized. So you no longer need to resort to workarounds in order to install them on your Mac.
  • We have nightly and stable releases for OpenDingux now, including a special release for a beta firmware. This version should have significantly better performance. Supported devices for this platform include (but are not limited to): GCW Zero, RG350M, RG280V, and possibly more.
  • There are now nightly and stable releases for Linux available for both 64bit and 32bit x86 PCs in the form of AppImage bundles. These bundles come with a portable home directory with assets included, or you can use them with your existing settings and assets from the typical ~/.config/retroarch location. There are two available packages: one that includes the Qt desktop menu and one without, in case your system-installed Qt libs conflict with the ones it comes bundled with. The AppImage builds should work with most distros that were released in the last three years or so.

Release notes

  • There is no PCSX ReARMed core available for the Switch port as of yet. This will be added later.
  • The Direct3D 11 video driver now defaults to the ‘flip model’. There will be a setting added later that will make it possible to switch between ‘flip model’ and ‘blit model’. Flip model is supposed to be more performant and allow for better performance in windowed/borderless fullscreen modes.
  • As mentioned earlier, Windows installers/executablers are currently not codesigned, so expect SmartScreen to warn you about them. We hope to be able to fix this as soon as our Extended Validation codesigning certificate is fully operational.
  • There is currently no Windows 95/98 version of RetroArch available, or any of the MSVC2003 cores in fact. Expect these to be added back later.

Some highlights

  • Overlay improvements:
    • Full position/scaling configuration, automatic scaling, automatic hiding when a controller is connected
    • A new high quality default gamepad overlay: neo-retropad(-clear)
  • File browser improvements: most menu entries now (optionally) remember last selected directory/file (load content, shaders, etc.)
  • Support for saving per-directory core options and deleting core option overrides
  • Improvements to input configuration: new drop-down lists, proper menu ordering of input binds, cosmetic clean-ups (basically all of sonninnos’s stuff)
  • Option to automatically enable ‘game focus’ mode when running/resuming content
  • Many new video filters for platforms without shader support
  • RGUI: CJK and Russian language support

Changelog

We can’t possibly list everything since it has been such a long time since the last stable. Nevertheless, here is the changelog broken down as best as we could.

1.9.1

  • 3DS: Graphics widgets support
  • 3DS: On error, only init gfx on salamander build. This prevents graphical issues if the gfx is already initialized. Which should always be the case if called from a running core
  • 3DS: Update error applet
  • 3DS: Enable online Core Updater
  • 3DS: Guard threading
  • 3DS: Allow sideways screen rotation
  • 3DS: Enable threading and add a threaded audio driver
  • ANDROID: Implementation of fullscreen over notch function (for Android 9.0 and up)
  • ANDROID: Add Play Store module support.
  • ANDROID: Add option to switch all installed cores to Play Store versions
  • AUDIO: Memalign audio buffers to 64 bytes. This is the most common cache line size, helps with performance. Also fixes issues with platforms like PSP that wrongly assume that malloc returns aligned buffers (to 16bytes). This recently broke the PSP builds
  • AUDIO/ALSA: Fix float format detection
  • AUDIO/JACK: Deinterleave in the process callback. This allows us to avoid the extra copy to the deinterleave buffer and lets us use only a single jack ringbuffer
  • AUDIO/JACK: (Audio/JACK) Fix non-blocking write. Previously we would wait on the condition variable even in the non-blocking case. This improves fast-forward performance massively and brings JACK in line with other backends in that regard
  • AUDIO/XAUDIO2: Fix threaded audio bugs with cores like Dinothawr
  • CONFIG: Add support for saving per-directory core options and deleting core option overrides
  • CONFIG: Enable saving of changed parameters when ‘#include’ directives are used
  • CONFIG/DIRS: Enable configuration of the directories used for Favorites, History, Images, Music and Video playlists
  • CONFIG/REMAPS: Allow loading core remaps without content
  • CONFIG/OVERRIDES: Fix empty override paths when launching without content
  • CHEATS: Maximum search value corrections
  • CHEEVOS: Generic memory mapping using rcheevos
  • CHEEVOS: Ensure badge textures are released before video driver is deinitialized. Should fix crashes with slang shaders.
  • CHEEVOS: Include achievement runtime state in save states
  • CHEEVOS: Prevent hardcore toggle when emu-handled cheats are active
  • CHEEVOS: Add confirmation submenu to achievements hardcore toggle
  • CHEEVOS: Calculate leaderboard widget spacing based on video resolution
  • CHEEVOS: Show unsupported core message when viewing achievement list for unsupported core
  • CHEEVOS: Allow disabling leaderboard notifications and trackers separately
  • CHEEVOS: Add display widget for active leaderboards
  • CHEEVOS/CORE OPTIONS: Core options blacklist. Disables hardcore mode when certain core options are set
  • CLI: Add option for quitting on close content
  • CONTEXT/DRIVER SWITCHING: Allow context switching from gl to glcore
  • CORE OPTIONS: Add option to reset all core options for current core/content
  • CORE OPTIONS: Add per-folder core options
  • CRT/SWITCHRES: Improvements
  • CRT/SWITCHRES: Low resolution switch bug fix – This allows resolutions lower that 32×224 like 256×224 to work
  • CORE DOWNLOADER: Enhanced core downloader search functionality
  • D3D10: Should now be able to use shaders with hardware-accelerated libretro cores
  • D3D11: Should now be able to use shaders with hardware-accelerated libretro cores
  • D3D11: Skip shader/stock blend when we don’t have a texture. This happens if the core calls video_cb with the frame set to null on the first frame, and was causing black screens/driver resets. The ffmpeg core seems to do this.
  • D3D11: Fix shaders with scaled framebuffers
  • D3D11: Add flip model support – fallback to blit model for OSes where flip model is not supported (windows 7 and earlier). Will add a menu option later allowing the user to switch inbetween the two
  • D3D12: Should now be able to use shaders with hardware-accelerated libretro cores
  • D3D10/11/12: Increase sprite capacity, we need this so that the hardware rendered menu drivers doesn’t glitch out
  • DRM: Fix race condition in drm_surface_set_aspect
  • DRM/KMS: add support for custom HDMI timings / modes
  • DATABASE: Fix crash that could happen when selecting cursor
  • DATABASE/EXPLORE: Fix – Prevent segfault when accessing ‘Explore’ menu
  • EMSCRIPTEN: Only report back one screen pointer for rwebinput, fixes lockup when clicking on an overlay
  • FILEIO/PERFORMANCE: Only attempt to call dir_check_defaults once per runtime session
  • FILEIO/PERFORMANCE/3DS: Increase file buffer size and savestate chunk size. This seems to help with saving large savestates
  • FONTS: Improve handling of Arabic and Persian text
  • FONTS/FREETYPE: Use fontconfig to select fonts if available
  • INPUT: Add hold mode for turbo fire ‘Single Button’
  • INPUT MAPPING: Refresh bind list on device type change
  • INPUT MAPPING/REMAPPING: Minor bugfix – Remap file browsing starts navigation at input_remapping_directory even if the core-subdir (where saved files go) exists Having remaps for many different cores makes finding the active core files cumbersome, especially because remaps are not compatible between different cores (but maybe for cores emulating the same hardware)
  • IOS: Take out ‘Core Downloader’ from iOS 9/iOS 11 builds
  • IOS: IOSApp doesn’t crash anymore when a file is shared to it
  • INPUT: Keyboard device mapper rework

  • INPUT/WINDOWS/DINPUT: Mouse grab fixes
  • INPUT/WINDOWS/RAWINPUT: Key position fixes
  • INPUT/WINDOWS/RAWINPUT: Mouse grab fixes
  • INPUT/WINDOWS/RAWINPUT: Prevent outside window mouse clicks when grabbed
  • INPUT/WINDOWS/RAWINPUT: Option for disabling Windows hotkeys
  • INPUT MAPPING/REMAPPING: Major bugfix – Remap file having a different device type requires manual intervention after loading for the core to register the type properly
  • JSON: New faster json parser/writer library rjson
  • JSON/RJSON: Replace rapidjson parser/writer in discord-rpc with rjson
  • LIBRETRO: Add API extension for cores to query the number of active inputs provided by the frontend
  • LIBRETRO: Ensure RARCH_CTL_CORE_OPTIONS_LIST_GET returns false if no core options are available
  • LIBRETRO: Add API extension for overriding frontend audio latency
  • LIBRETRO: Add API extension for cores to monitor frontend audio buffer occupancy
  • LINUX: Also show /run/media or /run/media/$USER in drives list

  • MENU/NOTIFICATIONS: On-Screen Notifications’ menu clean-ups
  • MENU/NOTIFICATIONS: Add option to show/hide Refresh Rate notification
  • MENU/FILEBROWSER: Start auto-selecting last used path for more file browser menu entries
  • MENU/INPUT: Input port label adjustments
  • MENU/INPUT/XMB: Proper control port icons

  • MENU/QUICK MENU: Add remap clearing ability under Quick Menu controls
  • MENU/QUICK MENU: Cap ‘State Slot’ drop-down list to a maximum of 1000 (+Auto) entries
  • MENU: Customizable menu scroll hold delay.
  • MENU/DESKTOP: Fix mouse cursor limited by window range on F5 press
  • MENU/DESKTOP: Add simple shader option

  • MENU/OZONE: New Theme – Twilight Zone
  • MENU/RGUI: Add 3:2, 5:3 and 3:2/5:3 (centered) aspects
  • MENU/RGUI/TEXT RENDERING: Add Russian language text support
  • MENU/RGUI/TEXT RENDERING: Add support for CJK punctuation glyphs

  • MIDI/WINMM: Fix winmm midi driver hanging on content closing
  • NETWORK: Add READ/WRITE_CORE_MEMORY network commands
  • NETWORK: Fix backwards condition in socket blocking behavior
  • NETWORK/NETPLAY: Attempt IPv4 when IPv6 fails
  • OGA/VIDEO: support for OGS
  • OGA: This keeps the tradition DRM driver along with the OGA one. The probe function skips the driver if the screen is non rotated to fall back to the regular DRM driver.
  • OGA: Fix messages from not disappearing
  • OGA: Implement RETRO_ENVIRONMENT_GET_CURRENT_SOFTWARE_FRAMEBUFFER. This is a faster rendering codepath for software rendered libretro cores that some libretro cores use right now. Video drivers in RetroArch have to explicitly implement this for this codepath to work at runtime.
  • OPENDINGUX: Add/Optimise rumble interface
  • OPENDINGUX: Fix frozen video when enabling fast forward
  • OPENDINGUX/SDL: OSD font clean-up
  • OPENDINGUX/SDL: Enable selection of image interpolation method when using ‘sdl_dingux’ gfx driver
    • OPENDINGUX/SDL: Enable integer scaling when using the ‘sdl_dingux’ gfx driver
  • OVERLAYS: Add option to scale overlays automatically (with aspect ratio correction)
  • OVERLAYS: Hide Overlay When Gamepad is Connected. Overlays will be hidden automatically when a gamepad is connected in port 1, and shown again when the gamepad is disconnected.
  • OVERLAYS: New default overlays for mobile (neo-retropad)
  • OVERLAYS: In addition to overlay scale, the user can now set an Overlay Aspect Adjustment factor. Most overlays are designed for 16:9 displays, which means they become stretched/ugly on modern wide aspect phones and suchlike. By changing the Overlay Aspect Adjustment factor, a user can scale the overlay width/height to achieve a uniform appearance regardless of display resolution.
  • OVERLAYS: Since scaling a gamepad overlay can result in buttons being squished too close together (or being pulled too far apart), the user can now adjust the effective spacing of the different ‘halves’ of an overlay via Overlay Horizontal Separation and Overlay Vertical Separation factors. Overlay Horizontal Separation divides the overlay in two vertically (left/right, at the centre point), and applies a spacing offset (positive or negative) between the UI elements on each side; Overlay Vertical Separation does the same, but the split is horizontal (top/bottom)
  • OVERLAYS/FIX: The Overlay X Offset and Overlay Y Offset options have been fixed, and now work correctly
  • OVERLAYS/FIX: All of the above options (and Overlay Scale) are configured and saved independently for landscape and portrait display orientations – so adjusting everything for a nice landscape layout won’t break the portrait display
  • OVERLAYS/FIX: When using the Vulkan gfx driver, memory is leaked every time an overlay is freed
  • OVERLAYS/FIX: When threaded video is enabled, loading overlays with no images (i.e. utility-type overlays, where everything is hidden until the screen is touched) can generate segfaults due to improper usage of realloc()
  • OVERLAYS/FIX: When Show Inputs on Overlay is enabled, ASAN reports bit shift errors due to an incorrect range check when handling turbo inputs – essentially, there is no upper limit to the considered input id range, which means overlay hotkeys (menu toggle, etc.) are incorrectly treated as having turbo support, causing bit shifts using wildly inappropriate id indices
  • PLAYLISTS/PORTABLE: Fixed first load initialization
  • PS2: Added Multitap support (up to 8 players)
  • PS2: Fix for not recognized digital and other non-standard controllers
  • PS2: Fix Quitting from RA
  • PS2: Add Audio mixer
  • REWIND: Prevent ‘Rewind Frames’ from being set to ‘1’ incorrectly on load content
  • RUNAHEAD: Add Run-Ahead Toggle hotkey with notifications
  • RBUF/ANIMATIONS: Simplify gfx_animation by switching from dynarray to rbuf
  • RBUF/CORE UPDATER: Replace static entries array with dynamic array via RBUF library
  • RBUF/M3U: Replace static entries array with dynamic array via RBUF library
  • SENSORS: Android (crash-)fixes/improvements + add option to disable sensor input
  • SDL2/VIDEO: Get the SDL2 video driver to work in Wayland/KMS
  • SAVESTATES: Adding savestate garbage collector for autoincrement stavestates. As some issues indicate, there’s an issue with the autoincrement save slot feature: slot index will increase and very old saves won’t be deleted. This adds support to delete old save states with a user defined save state limit (global). Instead of wrapping around the slot counter it will simply delete the oldest save, since it is simpler. For now there’s a limit of one deletion per save, which ensures a user cannot delete many saves by accident if they set the limit too low.
  • SAVESTATES/SAVEFILES: Ensure save file and playlist compression is disabled by default
  • SHADERS: Add option to remember last selected shader preset/shader pass directories
  • SHADERS: Use last selected shader preset directory when changing shaders via previous/next hotkeys
  • SHADERS: Remove Parameters line
  • SHADERS: Shaders fix for duplicate parameters loading bug
  • SHADERS: Fix Crash change num shader passes in UI
  • SHADERS/SLANG: Fix slang shaders with rotation
  • STREAMING/FFMPEG: Add Facebook Game Stream option (for embedded ffmpeg core-enabled RetroArch builds)
  • SWITCH: Fix input bind icons being off by one line
  • SWITCH: Fix audio issues
  • TLS/SSL: Add BearSSL support, as alternative to mbedTLS
  • VIDEO: AddVariable BFI (Black Frame Insertion)
  • VIDEO/DRM GO2: Dynamic resolution support
  • VIDEO FILTERS: Video filter optimisations
  • VIDEO FILTERS: Add several LCD-effect video filters
  • VIDEO FILTERS: Gameboy/Dot_Matrix video filters: Add XRGB8888 support
  • VIDEO FILTERS: Add Normal4x video filter
  • VIDEO FILTERS: Add ‘Upscale_256x-320×240’ video filter
  • VIDEO FILTERS: Add ‘Upscale1.5x’ video filter
  • VITA: Disable temporarily VitaGL
  • VITA: Fix bubble name
  • VITA: proper handling of boot params
  • VITA: Default menu scale 1.5x to improve readability
  • WIFI/LAKKA: Add a proper WiFi menu, with Enable/Disable & Disconnect options. This also allows WiFi passwords to be remembered. The underlying tool (connman) allows to store passswords (that’s why it auto connects whenever you boot a Lakka device), so we expose this so that the user does not have to re-input the pass when connecting to a saved wifi.
  • WII/HID: Added HID support for HORI mini wired ps4 gamepad
  • WINDOWS: Add support for accelerators to main win32 message loop
  • WINDOWS: Add accelerators for Open (Ctrl+O) and Fullscreen (Alt+Enter)
  • WINDOWS: Fixes some file I/O failures on Windows when paths are longer than 260 characters.
  • WINDOWS: Fix crashing on startup on Windows when using Chinese Simplified language.
  • WINDOWS/XP: The OpenGL 1 video driver is now the default for maximum backwards compatibility upon first startup. It’s of course always possible for the user to change this.
  • WINDOWS/MENUBAR: Load accelerators, Localize Win32 menu items to current language, and display shortcut keys
  • WINDOWS/MENUBAR: Add ‘Reinit’ to Menubar
  • WINDOWS/MSVC: Fix rewind crash on MSVC build when using SSE2
  • UWP: Don’t default to XMB menu by default, default to Ozone instead
  • UWP/VFS: Use Win32 file APIs when possible – better file I/O performance
  • WIIU/FILEIO/PERFORMANCE: Faster startup times – remove the path_is_valid() call when loading textures
  • WIIU: Fix touchscreen mouse emulation

RetroArch for iOS/tvOS nightlies available starting today!

Libretro Team


Starting today, we will start offering nightly versions of RetroArch for iOS and tvOS on our buildbot!

In the past, harakari would grace us every month with a pre-compiled version that we then had to manually upload to our buildserver. Now, it’s fully automated, so both iOS and tvOS versions of RetroArch will be built with each nightly and stable cycle!

Where to get it

Our Downloads page links to the latest nightlies for iOS/Apple TV.

The iOS version requires you to have iOS 11 or later installed.

How to install


Installing sideloaded apps on iOS and tvOS devices is a bit more complicated than it is on Macs. If you want to use the binaries on our site, this is what you have to do:

Get a Apple Developer Certificate
Apple asks about $100 per year for individuals. You will then have to re-sign the .ipa file that you download from our site. You can read more on how to do this here.

NOTE: You can use the program https://github.com/xndrs/XReSign on your Mac to re-sign as well, just to list another option.

We’d like to be able to provide a more easy and convenient way to install RetroArch on iOS/tvOS in a legal way in a manner we approve of (no ads, no monetization, etc.).

iOS/tvOS notes

No Core Installer – The Core Downloader is useless for these versions. It will likely be hidden/removed altogether in the future since it currently serves no purpose as cores also need to be individually codesigned.

First-time asset extraction – On first startup, it will extract the assets from assets.zip. You will notice it starting up with low-res assets and telling you to wait until this process has finished. Fortunately, this will only happen once and will not happen again afterwards.

How many cores available at launch?

There should be over 84+ cores available for iOS and tvOS. Just like the ARM Mac version, we are far from done here, and you’ll see this core library rapidly expand as we add more and more cores.

More ARM Mac cores added

In the meantime, we have added even more cores for the ARM Macs. We are now up to 93 cores, up from the 75 we started with a few days ago!

RetroArch for Apple Mac M1 softlaunches today!

Libretro Team

We’re happy to announce that RetroArch for Mac M1 will be available for download starting today on our website! Get it here.

We’ve put a significant amount of effort into our new infrastructure to ensure that all the RetroArch binaries for Mac (whether they are nightlies or stables) are now codesigned and notarized. This way, it no longer requires you to disable GateKeeper or start up the program in an obtuse way to get the program to start.

Two versions/where to get it

There are two versions for now:

  • RetroArch with OpenGL (for x86 x64 Macs) (latest nightly here)
  • RetroArch with Metal (for x86 x64 / ARM Macs) (latest nightly here)

As always, you can find these versions on our Download page. If you browse the Download page on a Mac, it will even show a convenient ‘Stable’ and ‘Nightly’ button for both versions.

NOTE: There is no Qt support yet in these versions. This means that the Desktop Mode (triggered with F5) is not available in these builds as of this time. When/if we add this we will inform you of this in a future blog post. Stay tuned for further information on that.

There is also another problem with Qt that pertains to ARM Macs – there is no official support yet. All the stable binaries out right now are for Intel Macs. Hopefully this situation will improve later on so that ARM Mac support comes out of the box.

RetroArch with Metal (for x86 x64 / ARM Mac – Universal app

RetroArch with Metal (for x86 x64 / ARM Macs) is a ‘universal’ version. This means that it will work on both ARM and Intel Macs. It uses the latest technologies available in modern Macs, like a new CoreAudio 3 driver, and a Metal graphics driver. The only disadvantage is that there is no OpenGL support. We might want to include this later on still in the build, but we are not sure yet if this will make sense for the universal build. I guess it all depends on how long Apple will keep it in ‘deprecated’ mode before removing it altogether.

RetroArch with OpenGL (for x86 x64 Mac)

RetroArch with OpenGL (for x86 x64 Macs) will only work on Intel Macs. You will be able to run it on an ARM Mac with Rosetta2, but for a more optimized experience you definitely want to go with the former version (Metal). You might still want to use this version though if you need some OpenGL-based libretro cores to work.

State of the ARM Mac RetroArch port

There are currently 75 Libretro cores available as of this writing. You can get them by going to Online Updater -> Install Cores inside RetroArch. We are going to be adding more as time goes on.

The ARM Mac version uses Metal as the video driver. There is no OpenGL driver. This means that OpenGL-based cores will currently not work on this version. If you want to use a core that requires OpenGL to function, you will have to download and install the x86 x64 version of RetroArch (with OpenGL) on your Mac and rely upon Rosetta2 emulation. Yes, it’s slightly inconvenient to have two versions of the same app installed on your computer. Hopefully later on we can find a solution so that this is no longer necessary, whether it’s through adding OpenGL driver support (assuming OpenGL remains available and won’t be removed altogether as we fear Apple might do) or whether that means going with some middleware wrapper that translates OpenGL to Metal.

Setup

In order to install RetroArch on your Mac, you need to make sure that your Mac is configured to allow apps downloaded from “App Store and identified Developers”. Go to System Preferences, Security & Privacy. Go to the tab 'General' and make sure that 'Allow apps downloaded from' is set to 'App Store and identified developers'. If it isn’t, click on the lock to make the necessary changes.

After this, you should have no problem installing RetroArch from our website. Download the zip file from our site, unzip it, this will give you a .dmg file. Mount the dmg file by clicking on it. Now simply drag the RetroArch icon over to the Applications icon. And you should be done!

NOTE: We changed the way assets are dealt with in RetroArch for Mac. Previously, assets were bundled in the .app itself and they would be stored there as well. Now, they are stored in a support directory in your user partition instead.

There is now also a first-time asset extraction process. Be aware that if the file ~/Library/Application Support/RetroArch/configs/retroarch.cfg already exists, it won’t try to extract the assets at first-time startup. Please keep this in mind in case you see low-resolution bitmapped fonts without any icons. Alternatively, you can always just update the assets directly from within the app by going to Online Updater, and selecting ‘Update Assets’.

Final thoughts

Lastly, we can tell you that the ARM-optimized version of RetroArch runs great on current Apple M1-based hardware. We are quite impressed with the overall level of performance on display, and our first priority will be to expand the amount of cores that are supported. Right now we have 75 Libretro cores available but we should be able to reach a number closer to the x86 x64 version.

Special thanks

Special thanks to Xer The Squirrel, kivutar, harakari and others for helping out with the key signing and work on our new infrastructure. We wouldn’t be at this stage right now without them!

Stella 2014 Core improvements – now fullspeed on OpenDingux devices, and more

Two new core options have been added:

Color Depth (Restart): This allows the user to select between RGB565 and XRGB8888 pixel formats. At present, the core forces XRGB8888, which is very slow on some platforms. Selecting 16-bit colour can significantly improve performance.

Interframe Blending: This enables the (crude) simulation of CRT phosphor ghosting effects. Simple performs a 50:50 mix of the current and previous frames. The Ghosting options accumulate pixels over successive frames, with persistence from 65% to 95%.

The main purpose of Interframe Blending is to alleviate the flickering that is common in many Atari 2600 games, caused when developers used the workaround of toggling sprites on alternate frames to show more simultaneous on-screen objects than the hardware strictly allowed. For example:

  • Setting Interframe Blending to Simple will remove the flashing in Asteroids
  • Setting Interframe Blending to Ghosting (95%) will almost completely remove the flashing in Pac Man

Ghosting can also produce nice effects in games that don’t flash – e.g. Beamrider looks rather special with Ghosting (85%).

Care has been taken to implement these options in a performant manner. With 16-bit colour depth, all Interframe Blending methods run full speed even on an RG350M (OpenDingux) with 2x video filters.
