General changelog

– 3DS: Now correctly reports amount of CPU cores.
– 3DS: Frontend rating is now correctly implemented for both New 3DS/2DS and Old 3DS/2DS.
– 3DS: Initial networking support, HTTP requests won’t work yet.
– 3DS: Now reports memory and battery state.
– AUDIO: Added ‘Audio Resampler Quality’ setting to Audio Settings. Setting this higher will increase sound quality at the expense of sound latency and/or performance. Setting this value lower will improve sound latency/performance at the expense of sound quality. Only has an effect if the Sinc resampler is used, and you have to restart the game for changes to take effect.
– CHEEVOS: Fix unofficial achievements not being loaded.
– CHEEVOS: Show savestate menu entries when no achievements are found even if hardcore mode is enabled.
– CHEEVOS: Support Neo Geo Pocket.
– COMMON: Bugfix for issue related to ‘Windows mouse pointer visible when running MESS or MAME cores’.
– COMMON: Fix bug ‘Last item in a Playlist is ignored’.
– COMMON: New LED API. Driver implemented for Raspberry Pi, proof of concept implemented for core MAME 2003.
– COMMON: Add quick menu option to watch shader files for changes and recompile them automatically (Linux only for now).

– GUI/XMB: Allow changing menu scale to 200%.
– GUI/XMB: Works now with D3D8, D3D9 Cg, D3D11 and D3D12 drivers. Menu shader effects currently don’t work on D3D8/D3D9 Cg.
– HAIKU: Restored port.
– KEYMAPPER: prevent a condition that caused input_menu_toggle to stop working when a RETRO_DEVICE_KEYBOARD type device is enabled

– OSX: Modify HID buttons detection algorithm.
– QB: Added –datarootdir.
– QB: Added –bindir and –mandir and deprecated –with-bin_dir and –with-man_dir.
– QB: Added –docdir.
– SHADERS: Allow saving of shader presets based on the parent directory (Saving one for */foo/bar/mario.sfc* would result in *shaders/presets/corename/bar.ext*). We decided it’s safer to still isolate the presets to a single core because different cores may treat video output differently.
– SHADERS: Don’t save the path to the current preset to the main config. This was causing weird behavior, instead it will try to load *currentconfig.ext* and it will save a preset with that name when select *apply shader preset*. The resulting shader will restore properly after restarting and even after core/parent/game specific presets are loaded
– SOLARIS: Initial port.
– SWITCH: Initial Nintendo Switch port, based on libtransistor SDK.
– PSP: Enable threading support through pthreads.
– SHADERS: SPIRV-Cross/slang shader support for D3D11.

– SUBSYSTEM: Subsystem saves now respect the save directory
– SUBSYSTEM: You can now load subsystem games from the menu (see for caveats)
– VULKAN: Fix swapchain recreation bug on Nvidia GPUs with Windows 10 (resolved in Windows Nvidia driver version 390.77).
– WINDOWS: Improved Unicode support (for cores/directory creation and 7zip archives).
– WINDOWS: Show progress meter on taskbar for downloads (Windows 7 and up).
– WINDOWS: WS_EX_LAYERED drastically decreases performance, so only set it when needed (transparency in windowed mode).
– WIIU: Overlay support.
– WIIU: Transparency support in menu + overlays.
– WIIU: Increased stability during core switching.
– WIIU: Shader support.
– WIIU: Menu shader effects added (shaders).
– WIIU: Add missing time/clock support. (also fixes RTC [Real Time Clock] in Gambatte)


New Direct3D 11/12 driver

RetroArch 1.7.1 now features very robust and feature-complete Direct3D 11/12 drivers for Windows users! Direct3D 11 should be available to users starting as of Windows 7, whereas in order to use Direct3D 12, you need Windows 10.

See here the following features:

  • Supports Slang shaders, the same shader format that Vulkan uses
  • Suports the menu; supports MaterialUI and XMB.
  • Supports overlays.
  • All menu shader effects have been ported.

Do note that right now, it is recommended you use the Direct3D11 driver instead of Direct3D 12. D3D11 is many times faster than D3D12, and while there are still gains to be had, we are not necessarily sure if the D3D12 driver will ever be able to outperform the D3D11 driver.

The Direct 3D 11/12 video drivers should work with any libretro core that does not require either OpenGL or Vulkan to function.

Some minor features which are currently not available is features like Max swapchain image control, GPU Hard Sync and/or Black Frame Insertion.

Emscripten/Web Player back in action and better than ever

Toad King has graciously not only restored the Web Player, but made it better than ever.

Now using WebAssembly under the hood, not only is it a lot faster, but it also now has the XMB menu by default and should work properly with builtin gamepad support from your browser.

You can find the Web Player here. You can also reach the Web Player at any time by going to and clicking on ‘Web Player’ in the topright hand part of the site.


Subsystem support – Game Boy 2-player Link, Super Game Boy support with SNES emulators, etc

This feature allows cores to specify a subsystem, which may be a different system like in this video, or an add-on (think Super Gameboy / Genesis lock on).

Previously, cores that supported subsystems (think Super Game Boy / Sufami Turbo with SNES9x emulators) needed to be started from the commandline in order to be able to use Super Game Boy/Sufami Turbo mode.

The following cores should already have subsystem support:

  • Same Boy (allows for up to 2-Link netplayer)
  • bSNES (Super Game Boy and Sufami support should work through the menu)

NOTE: You need to set the Filebrowser Directory to your starting point directory if you want to use the subsystem feature. It will not work properly without.

Universal shader spec gaining steam – Vulkan/D3D11/D3D12/WiiU all using the same shaders now

There are several video drivers now that all make use of the same universal shader format, Slang:

  • Vulkan
  • Direct3D11
  • Direct3D12
  • WiiU

What this means is that all these video drivers are able to use the same shader format without having to convert from one format to another. The magic happens courtesy of SPIRV-Cross, itself a Khronos project.

We hope that in the future, the slang shader spec will be supported by most of RetroArch’s video drivers (such as OpenGL and the other Direct3D drivers). This represents a very important step towards realizing that ultimate goal.

Veteran RetroArch users will probably remember that we first tied our wagon to Nvidia’s Cg shader format. As that spec gradually fell out of favor and even Nvidia abandoned it wholesale, it was for a time uncertain for us which new format we would have to go with. You had GLSL on mobile and desktop GL, and HLSL for Direct3D. Now, with SPIRV-Cross, we finally have an exit strategy for the increasingly deprecating Cg ecosystem of shaders.

That being said, we still intend to continue supporting Cg and the shader system, and platforms like PlayStation3 and Xbox 360 wholly depend on it in fact.

WiiU port vastly improved

The WiiU port has been significantly improved upon in many ways.

  • Overlay support.
  • Transparency support in menu + overlays.
  • Increased stability during core switching.
  • Shader support (slang).
  • Menu shader effects added (shaders).

There are shaders out in the wild as add-on packs. Shaders are not compiled at runtime, unlike on PS3.

Switch port

OK, so we can’t roll a public release out for this one yet since it still relies on baking in the content through squashfs. However, the Switch homebrew is recently heating up with the release of the Homebrew Launcher, and also competing SDKs like Libnx.

However, we hope that by the time 1.7.2 comes out, we will have something in a ready-made fashion available to all.

Configurable audio resampling

While RetroArch is also well set to deliver a latency experience almost on par with the actual hardware under the best circumstances, it also continues to help people find new solutions to their one core common problem – latency.

If you are using the Sinc resampler, you can set the quality of the resampling by going to Settings -> Audio and adjusting ‘Audio Resampler Quality’. The highest settings will produce the best possible sound quality at the expense of performance and/or latency, while the reverse is true by setting it to one of the lower values.

What’s coming next for RetroArch

We will have a separate blog post on this soon, as well as more separate blog articles detailing some of the other progress that has been made on the cores front.
