Steam Launch lineup revealed

Libretro Team

So, it’s been a long time since we (prematurely) announced our intent to launch RetroArch on Steam. We’re nearing the finish line now however, so now is as good as any a time to start discussing how things are going to roll out.

Will launch on Windows first (Linux later)

We will be releasing on Windows first, with a release on Linux scheduled later (no ETA).

We are trying to limit our support burden at launch here since we are (understandably) concerned about the large amount of support requests and feedback we are bound to be receiving. Adding Linux right from the bat would further exacerbate that.

10 Cores Available On Launch Day

We are deciding to launch with 10 cores at launch. These cores have already been approved and uploaded on Steam. They are as follows:

There will be no ‘Core Downloader’ in RetroArch, or anything that is not hosted on Steam in fact. To obtain cores, you need to install cores separately that we provide as ‘DLC’. These are all free just like RetroArch itself.

NOTE: We need to stress – on its own, without installing any of the cores, the most you will be able to do with RetroArch is watch some movie files and playback music files through its builtin ffmpeg core. To make it do anything else, you will have to install cores.

Differences between regular RetroArch and Steam version

Apart from these aforementioned changes, there will be no substantial differences for now in the Steam version. We understand that even though we have consistently improved the User Experience and tried to make things more easily accessible that we will still be in for a lot of criticisms over the initial learning curve, so we’ve pretty much resigned to the fact that this will happen and will just brace for impact and try to do as much as what we can with the criticism that will inevitably be piling on. We will try to do our best to be as receptive to the feedback as possible with the thickest amount of skin possible, and try to suitably make some much needed UI changes.

This is also what helped inform our decision to go with 10 cores. We could have launched with over 60 cores, sure, but the ensuing fallout would have been a mess and it would have been near impossible to focus on bug reports and issues piling in. By focusing on 10 cores, we can do some much-needed Quality Control where issues inevitably get picked up, we can respond to it and in the process improve the quality of the core. This kind of isolated feedback time with a specific batch of cores is something we have found ourselves in the past always lacking, since it was always off to do the Next Big Thing as new features, cores, and other developments are made on an almost weekly basis. This gives us the much-needed time to focus on a specific batch of cores and polish them before we move on to the next batch of cores.

RetroArch 1.8.8 released!

Highlights

Add option to sort playlists after name truncation (Ozone)

A couple of users have complained about a feature we made in 1.8.7 (Fix sidebar playlist sort order when ‘Truncate Playlist Names’ is enabled). This new addition makes the new sidebar playlist sorting behaviour optional via a Sort Playlists After Name Truncation setting under User Interface > Appearance. When disabled, playlists will be sorted the old way (according to file name), not by display name.

Localization – big updates and crowdsourced

A new language has been added, Slovakian. And plenty of the existing languages have received big updates as far as localization goes.

But by far the biggest change is our transition to Crowdin. This allows non-programmers to more easily contribute localization changes/additions to RetroArch. You can see the completion status of the various languages on our Crowdin page.

Improved shader preset dirs

1.8.8 restores the original behavior of the “Save Shader Preset As” option, and improves the cycling of shaders by allowing to cycle the shaders on fallback directories if the Video Shader directory does not contain any preset.

Input Remapping Fixes

In 1.8.7, pressing RetroPad Start to reset a core input remap to the default setting did not work correctly – analog stick inputs get the wrong defaults, and inputs that are left undefined by the core are not set to the proper RARCH_UNMAPPED value.

1.8.8 fixes the issue.

RetroArch WiiU: Gamepad hotplugging support, theoretical multi-gamepad support

1.8.8 adds support for hotplugging WiiU Gamepads. Critically for users, this makes the driver no longer assume a Gamepad is present, so when it’s broken or out of battery or missing; the first Wiimote gets slot 1 instead (helpful when All Users Control Menu is off). I [quarkawesome] also made it check Gamepad channel 2 – while it’s impossible to connect a second Gamepad on a retail console, the code to do it still appears to be there. If that feature ever becomes a thing through CFWs, it’ll work here.

RetroArch P2 – New SDK/toolchain – big improvements

fjtrujy spent a lot of time adapting RetroArch PlayStation2 to the latest PS2 SDK. RetroArch PS2 is now being built with a modern version of the GCC compiler, and certain cores are already seeing massive speedups as a result.

As can be seen by the tweet, QuickNES went from 255fps with the old SDK to 429fps with the new SDK. This makes the core more than fast enough to use runahead – on a PlayStation2 of all things!

A newer C/C++ toolchain also will make it much easier to port over software to PS2, it was previously quite difficult to port C++ cores over to PS2.

fjtrujy also added Theodore to the list of cores supported.

RetroArch 1.8.7 released!

Libretro Team


RetroArch 1.8.7 has just been released.

Grab it here.

We will release a Cores Progress report soon going over all the core changes that have happened since the last report. It’s an exhaustive list, and especially the older consoles will receive a lot of new cores and improvements.

Remember that this project exists for the benefit of our users, and that we wouldn’t keep doing this were it not for spreading the love with our users. This project exists because of your support and belief in us to keep going doing great things. If you’d like to show your support, consider donating to us. Check here in order to learn more.

Highlights

There are many things this release post will not touch upon, such as all the extra cores that have been added to the various console platforms. We’ll spend some more time on that in a future Cores Progress Report post. We’ll go over some of the other highlights instead.

Netplay bugfixes

Some major netplay regressions snuck into version 1.8.5 and has remained a problem ever since. 1.8.7 finally fixes these issues.

New desktop-style Playlist View mode for MaterialUI

1.8.7 adds a new Desktop Thumbnail View to Material UI, available when using landscape display orientations. This is similar to Ozone’s playlist view. Above is a random screenshot showing what it looks like.

Notes:

  • The status bar at the bottom can be hidden by disabling Settings > Playlists > Show Playlist Sub-Labels
  • Touching/clicking the thumbnail bar toggles the fullscreen thumbnails view

This also represents a major refactor of MaterialUI’s menu entry handling code, which will make other kinds of playlist view mode easier to implement in the future.

Finally, this fixes two small existing issues:

  • Entry dividers now fade correctly during menu transition animations (this is subtle, and I only just realised that is wasn’t working!)
  • The ‘missing thumbnail’ placeholders now fade into view, just like normal thumbnails (previously, they were always displayed instantly, which was quite jarring)

Disable ‘Use Global Core Options File’ by default

1.8.7 changes the default setting of Use Global Core Options File to OFF.

This was only set to ON by default for consistency with legacy setups. There is no material benefit to this – in fact, a global core options file has the following downsides:

More file I/O – all options have to be read/written every time content is loaded or options are saved

Difficulty in editing option values by hand – e.g. sometimes this is necessary if a particular setting causes a core to crash, and if options for all cores are bundled together then sifting through them to find the one you need becomes a chore

Obsolescence – settings for old/unused/outdated cores hang around forever, and bloat the global options file without purpose. With per-core options, it is easy to remove settings for unwanted cores

Since settings are automatically imported from the legacy global file on first run when per-core files are enabled, changing the default behaviour will not harm any existing installation.

Don’t perform unnecessary cheevos initialisation when cheevos are disabled

Before, on all platforms with cheevos support rcheevos_load() is called each time content is loaded. This means the following happens even when cheevos are disabled:

  • If the core does not require the full content path (i.e. if RetroArch passes a data buffer directly), then a copy of the content data is made (up to 64 MB in size)
  • If the content is an m3u file, the file is opened and parsed to get the extension of the first file listed inside
  • A checksum is calculated for the content file extension
  • A task is pushed
  • A mutex is locked/unlocked several times

When Cheevos (Achievements) are disabled, all these things are unnecessary work, causing increased loading times and memory usage. On platforms with low memory (i.e. consoles) the unnecessary content data duplication is potentially harmful and may cause crashes.

1.8.7 very simply adds an ‘early out’ to rcheevos_load() which prevents the above unnecessary work when cheevos are disabled.

Cheevos: option to start a session with all achievements active

Adding an option to allow the players to start a gaming session with all achievements active (even the ones they have as unlocked on RetroAchievements.org).

When cheevos_start_active = true, instead of You have X of Y achievements unlocked, the player will see a message like this:

How the option looks in XMB:

And in Ozone:

Fallback directories for shader presets

This allows us to use the Menu Config and config file directories as fallback to store shader presets when the Video Shader directory is not writable by the user, thus following the same behavior shown by the “Save shader as” menu option.

This allows users to handle their own presets without having to mess with the directory configuration on distros such as ArchLinux, where shaders (among other assets) are managed through additional packages. But it also goes a bit further and changes the order of the preset directories, searching first on the Menu Config path, then on the Video Shader path, and finally on the directory of the config file.

This would improve the portability of the configuration for Android users, because they cannot explore the default shaders directory without rooting their devices. Moreover, I think it makes more sense, as regular configuration overrides are already being stored on the Menu Config path by default.

Testing
Assuming these directory values:

  • menu_config: /home/user/.config/retroarch/config/ (non-writable for testing purposes)
  • video_shaders: /home/user/.local/share/libretro/shaders/ (non-writable)
  • retroarch.cfg: /home/user/.config/retroarch/retroarch.cfg

    • The following menu options have all been successfully tested (see appended log output).

ChaiLove

  • Port: Ported ChaiLove core to 3DS
  • Port: Ported ChaiLove core to Android

HBMAME

Description: Emulator of homebrew and hacked games for arcade hardware

  • New core

VICE

Description: Commodore 64 home computer emulator

  • Split “Paddles” joyport type to first two RetroPads:
    Player1 vertical axis = Player2 horizontal axis
    Player1 2nd button = Player2 1st button
    Add speed modifier hotkeys (slower+faster) for paddles/mouse

    Because “Paddles” is in fact 2 controllers in one joyport, and currently it is read like a mouse with 2 axis and 2 buttons, this is not convenient for 2 player games, like Panic Analogue, which use paddles as 2 separate entities with one axis and one button.

  • Fixes for JiffyDOS, Disk Control & Statusbar –

    To evade JiffyDOS incompatibilities with CRTs, PRGs & TAPs, the allowance method is changed from whitelist to blacklist.
    Also M3U playlists of D64 images will allow, and playlists of TAP images will not
    Fixed not being able to insert disks at all when starting without content
    Drive type defaults to 1541, as in inserting D81s will not work for now, because drive type autodetection happens only on autostart
    Finetuned statusbar

  • Turbofire & JiffyDOS fix –
    Minor fixes:

    Turbofire pulse was off (value 2 was actually 4)
    No reason to allow JiffyDOS core option with anything other than D64 & D81, or is there..?

  • Remove Nuklear GUI, Add VKBD touch control –
    Replaced bloaty Nuklear with the lightweight VKBD from PUAE

    No drawbacks, only benefits: Touch control, better performance, simpler maintenance

  • Port: Fixed VICE core Android build
  • Port: Ported VICE core to 3DS
  • Port: Ported VICE core to Emscripten
  • Add support for disk control interface v1 (disk display labels)
  • x64: Exclude vicii-clock-stretch.c – vicii-clock-stretch.c is not really used on x64, it’s only for x128
  • Disable cpmcart on x128 –
    Both x128 and cpmcart have z80 cpu and both have z80_regs symbols.
    On platforms other than emscripten those symbols end up being aliased
    due to “-fcommon” behaviour. This would lead to very weird results if they
    would ever be used together.

    On real hw cpmcart is unnecessarry due to integrated CP/M mode

    In the emulator cpmcart is runtime-enable only on x64 and x64sc but
    the relevant code is still compiled-in.

    So just remove cpmcart.c and #ifndef to avoid references

  • Core option for disabling autostart joined with autostart warp
  • Statusbar improvements, VKBD transparency core option

GME

Description: Game Music Emulator core

  • Port: Ported GME core to PSL1GHT (PS3)
  • Port: Ported GME core to 3DS

prBoom

Description: Doom 1/2 game engine core

  • retro_run: Don’t attempt to run domm lop after exit – This fixes crash on exit on 3DS
  • Port: Added PSL1GHT port (PS3)

MelonDS

Description: Nintendo DS emulator

  • (Switch) Latest updates

P-UAE

Description: Commodore Amiga emulator

  • VKBD updates, CD turbo speed backport
  • WHDLoad changes (button overrides)
  • VKBD touch control –
    Only tested with Windows and mouse, since RETRO_DEVICE_POINTER also reacts with it. Hence also disabled real mouse control while VKBD is visible.
  • Port: Ported P-UAE to PSVita
  • Minor save state improvements
  • Extended ZIP support

ScummVM

  • Update to ScummVM 2.1.1
  • Allow launching games directly from game files

Mr. Boom

Description:

  • Port: Ported Mr. Boom to 3DS
  • Port: Ported Mr. Boom to Emscripten
  • Port: Ported Mr. Boom to PSP

  • Eliminate too verbose output – On 3DS stderr is printed on lower screen and is slow. This messes up the
    performance completely.

  • Add option to change sound quality – Even with the fast renderer (#116), the framerate on the PSP slows down at some points in some games. Reducing the sound rate can help increase the framerate in these cases.

    It’s not ideal but it’s better than frame skipping. [bmaupin]

ECWolf Wolfenstein 3D Libretro core WIP available today on Windows/Mac/Linux/Android!

Libretro Team

ECWolf Libretro running on RetroArch at high resolution and widescreen enabled

A new Libretro core is being made available for RetroArch and other Libretro frontends today! ECWolf is a Wolfenstein 3D source port game engine. This port is courtesy of phcoder.

ECWolf can run the following content:

  • Wolfenstein 3D
  • Spear of Destiny
  • Super 3D Noah’s Ark

It will be available today for the following platforms:

  • Linux
  • Windows
  • macOS
  • Android

It will probably be released over time on other platforms.

How to get it

There are two ways to install and/or update the ECWolf core:

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 ‘Wolfenstein 3D (ECWolf)’ from the list. It will then download and install this core.

How to play it with the shareware version

If you don’t have the full registered version’s data files to play with, you can still get the shareware version. We provide this in an easily obtainable way to you, so let’s go through the steps. Start up RetroArch first. Then do the following:

1. Go to Online Updater, ‘Content Downloader’.

2. Go to ‘Wolfenstein’, and download ‘Wolfenstein 3D (Shareware).zip’.

3. Now go back to the Main Menu. Select ‘Load Content’, and select the ‘Downloads’ directory. Select ‘Wolfenstein 3D (Shareware)’, and then select ‘WOLF3D.EXE’. Start this with the ECWolf core when asked about it.

Current status


This port is currently incomplete but already has a lot of functionality.

NOTE: You need the file ‘ecwolf.pk3’ inside either your System directory, or the same directory as your content. You can get this file from within RetroArch through the Content Downloader (see the previous paragraph, but instead of downloading ‘Wolfenstein 3D (Shareware).zip’, download ‘ecwolf.pk3’ instead.

Differences with standalone port

* Menus are removed and it goes straight to episode or skill selection
* All options are moved to libretro options
* Full screen control is also moved to normal libretro
* Load and save is moved to libretro facilities as well
* Quit is removed from the core and is to be handled in libretro way as well
* Invunerability cheat is moved to libretro options
* Gamma control is not supported. Use libretro filters.
* Currently has variable framerate support up to 360fps. Original game ran at 70fps.

Missing features

* Only IMF music is supported
* “Read This!” is missing
* “High scores” are also missing
* MLI cheat is missing
* Demo recording and playback are missing. Note: normal libretro demos are still there.
* F1 help is missing
* ID easter egg is missing
* Mouse and keyboard support, including corresponding config, is missing.
Only RetroPad currently works. You can control using retropad mappings
* ‘0’-‘9’ weapon selection is missing
* Buttons ‘zoom’, ‘reload’ and ‘altattack’ are missing. They’re used only in mods.
* Buttons ‘Strafe modifier’ and ‘status bar’ are missing
* Netplay is missing
* Difficulty confirmation screen is missing
* Resizing screen with +/- is not supported. Use options
* Commander Keen easter egg is missing
* Menu movement animation is missing
* Robert’s jukebox is missing

Known glitches

* Rewinding through intermission or death fizzling results in glitched screen
* Sometimes after loading a large asset, FPS drops. If that happens go to RetroArch menu for couple of seconds and then back
* The sound is currently a bit glitchy/crackly when running below 70fps (the game’s original framerate). We have found that there are far less sound issues at 70Hz and above (such as 120Hz).
* Frame pacing and frame time deviations can probably still be further improved.
