Yesterday marked RetroArch’s 10 Year Anniversary date. Today, we’re not only releasing a new RetroArch version, but we’re letting you know all the changes that have been made to the libretro cores since the last progress report.
Our last core progress report was on April 2, 2020. Below we detail the most significant changes to all the Libretro cores we and/or upstream partners maintain. We are listing changes that have happened since then.
How to update your cores in RetroArch
There are two ways to update your cores:
a – If you have already installed the core before, you can go to Online Updater and select ‘Update Installed Cores’.
b – If you haven’t installed the core yet, go to Online Updater, ‘Core Updater’, and select the core from the list that you want to install.
Final Burn Neo
Description: Multi-system arcade emulator
- Add Neo Geo Pocket Color support
- Latest updates from upstream
Flycast
Description: Sega Dreamcast/NAOMI emulator

- Haiku: Fix build
- Rewrite nvidia jetson nano build
- Make threaded rendering the default on all platforms. Synchronous mode enabled unless LOW_END is defined
- Info and warning for xBRZ upscaling core option

DOSbox Core
Description: DOSbox core
- Latest updates from upstream
- Add option for using 2axis joystick even when only one port is connected – this fixes input problems in “Super Off Road”, but other games might also need this.
- Add option for controlling log verbosity level – Since we can log to stdout now, it makes sense. Also, some frontends might not have configurable log verbosity levels.
- Add option for printing log output to stdout/stderr –
Useful if the frontend’s logging output is unreliable or too noisy (or
both) and we only want to see log output from the core. RetroArch does
have a configuration option for controlling frontend and core log output
seperately, but it’s bugged.
- Enable Voodoo on all platforms and regardless of fakesdl – Software-based Voodoo emulation doesn’t require SDL anymore so it should build fine everywhere.
- Don’t claim there’s Voodoo2 emulation – Oops. 12MB doesn’t actually mean Voodoo2. The current code only emulates the original Voodoo. The 12MB setting is just a non-standard memory configuration for the Voodoo 1.
- Add support for changing current core option values programmatically.
This is a hack. The libretro API does not actually support this. We
achieve this by replacing all current values with a bogus one to force
the frontend to forget the currently selected value, since it doesn’t
match the bogus one. We then submit the correct values again, but with
the default value set to the value we want to switch to. This forces
the frontend to switch to that value because the bogus value is now
gone and thus not a valid value anymore. Finally, we submit the values
again but with the initial default value (we only want to change the
current value, not set a new default.) The frontend will not switch the
current value, as the values themselves have not changed, just the
default has.
RetroArch seems to be well-behaved here and does the correct thing.
Other frontends might not play ball though.
- Hook up 3dfx core options
- Vita: Fix dynarec, fix build
- Add build options to make bassmidi and fluidsynth optional
- Fix ARM dynarec
- Correct cdrom sector size field length according to docs.
- Refactor input mapper –
Code should be simpler to understand now. This also fixes a bug where
inputs on the second port weren’t working before. Mouse emulation is now
possible on both ports and the default emulated mouse buttons have been
swapped with the speed modifier buttons (L/R are now mouse buttons,
L2/R2 the speed modifiers.) This is a saner default since not all
controllers have L2/R2 buttons.
- GHA: Support macOS 10.13 by building with GCC instead of XCode Clang
- Fix floppy image file size detection oopsie
- Improve disk control related code and move it to its own source file
- Make image file extension comparisons case-insensitive –
This fixes the issue where loading an image that has an upper-case
extension (like “.CUE” instead of “.cue”) results in dosbox mounting the
image itself without going through the libretro disk control interface.
We add new case conversion funtions for this (in the new util.h/util.cpp
files) because the existing conversion functions provided either by
dosbox or libretro-common are crap and we’re smarter than everybody
else.
- Add libretro disk control interface disk labels support –
Only retro_get_image_label_t for now. Leave retro_set_initial_image_t
and retro_get_image_path_t undefined as it’s not clear what the use
would be in case of DOS games, especially since we don’t handle m3u
files yet.
- Fix disk_replace_image_index always reporting failure –
This silly mistake caused the “Failed to append disc” error message in
RetroArch.
- Add core option for setting the free space when auto-mounting drive C
- Ensure overlay mount path ends with a dir separator –
Otherwise dosbox will write data in bogus directories in the overlay.
- Add option for mounting the executable’s parent dir as drive C –
Some pre-installed games expect to be installed in C:\GAMEDIR rather
than directly in C:\. This option allows these games to run without
having to modify their configuration files first.
- Enable PC speaker by default
- Fix direct content loading of DOS executables
- Fix BASSMIDI crashing during startup on 32-bit Windows
- Add BASS/BASSMIDI libs to core info file
- Add BASSMIDI MIDI driver –
The bass and bassmidi libraries are looked for in the frontend’s system
directory and loaded at runtime. This allows the core to work and be
distributed in a GPL-compliant way without those libraries.
DOSbox SVN

- Fix VDP1 rotation for Hang on and Power drift. It looks like a scale might be still needed for Capcom Generations 4
PCSX ReARMed
Description: Sony PlayStation1 emulator
- Android: Support for new lightrec API
- Update lightrec to latest upstream
- Minimize logs when loading a cheevos-compatible content
- Cleanup retro_run() –
– move input query into separate functions
– move internal fps display to separate function
- Hide other inputs from core options –
– This adds a core option to hide some input options like multitaps, player ports 3-8 and analog-related fine-tuning options.
– also combine dynarec-only options in one #define directive
- More core option fixes –
– This PR fixes core options and moves them to the related dynarec modes where they are implemented.
LIGHTREC = relates to platforms that supports the new Lightrec mode
NEW_DYNAREC = relates to previous dynarec implementation that is still used for some 32bit devices
– Dynarec Recompiler core option, both dynarec implementation can be enabled or disabled
- Move guncon options to update_variables –
– This should stop unnecessary RETRO_ENVIRONMENT_GET_VARIABLE callback and log spamming
- Fix some edge case where core can freeze upon loading content
- Automatically disable Lightrec when no BIOS is present, take 2
- cdriso: fix a disk switching deadlock when closing a CD image
- ARM NEON: Fixed bug where MSB of a 15-bit BGR color could corrupt green value.
- cdriso: fix a disk switching deadlock
- unai: Add ARM-optimized lighting / blending functions
Addendum on UNAI ARM-optimized lighting/blending improvements –
“Looking at the generated ASM on 3DS, I thought I could squeeze out some extra performance by moving the inner lighting and blending functions to handwritten A32 assembly. This gives a medium improvement generally (3-5fps faster on the beach in Crash 1) and a large improvement when doing lots of blending (46-48fps before, 57-60fps after, behind the waterfall in Water Dragon Isle in Chrono Cross).
Some other notes:
- I used the ARM11 MPCore (3DS CPU) timings for pipelining.
- I had a few stall cycles during lighting, so I used them to preserve the MSB for lighting and blending, which saved a store, load, and orr later on. ~3-6 cycles saved overall by doing that.
- I switched from u16 to uint_fast16_t, which is 32-bit on this platform. This saved a few useless uxth instructions for another few cycles. This shouldn’t affect other platforms, but I don’t know for sure. Could typedef if necessary.
- A lot of the speed improvement in blending comes from not using two instructions per and. For example, & 0x8000 — the compiler preferred to mask out bytes using bic 0x7F00 and bic 0x00FF. Both slower and seemed less correct for what we’re trying to do.”

Snes9x 2010
Description: 16bit Super Nintendo/Famicom emulator
- libretro: added granularity in SuperFX overclock –
There doesn’t seem to be any benefit of overclocking above 15 MHz
(150%). The user should be allowed to be more precise with their
overclock setting now.
- Fix MMC reg for 64bit builds –
Fixes a segmentation fault when playing large ROM games.
- Fix MMC bank register bit 7 (FuSoYa) –
Fixes the 64Mbit ExLoRom map.
- ROM: fail if ROM is invalid –
Fixes an issue whereby a non-SNES file would cause a segmentation fault.
This may occur if the selected ROM is corrupt, or a file has an
incorrect extension.
- APU: remove unused SoundSync –
Additionally modified the resampler to use buffer size as a parameter
instead of the number of samples within the buffer. Previously, the
buffer size was being changed to the number of samples, and then changed
back within the resampler.
- snes9x: add defines for unused multi-cart support –
The compiler was already optimising these unused functions out. The
libretro core can define SNES_SUPPORT_MULTI_CART 1 to re-enable support
for multi-cart in the future.
- snes9x: refactor defines and remove overscan –
Out of bounds memory fix from
- snes9x: APU: Fix buffer overrun –
Additionally:
This fixes linking with LTO.
Disable audio if an error occurs in init instead of continuing and
segfaulting.
- snes9x: reduce APU buffer to 64ms –
I believe this to be a more sane setting than a 1000ms buffer.
- snes9x: backport config from upstream –
Most options were not available in English, despite it being the default
language. All the options that were available in Turkish are now
available in English.
- snes9x: fix headercount increment
- libretro: fix pitch measurement
