## Version 1.2.0

**Release date:** 2021-12-28

### Release overview

The 1.2 release introduces multiple new features and brings extensive bug fixing and lots of other small improvements. Support for alternative emulators has been added which can be selected system-wide or per game. These alternative emulators are added to the es_systems.xml file, making it easy to expand or customize the configuration. For this release most of the available RetroArch cores have been preconfigured, and a couple of standalone emulators have been included as well.

A virtual keyboard has been added (some code borrowed from Batocera.linux) which is fully integrated and can be used to input text via a game controller. By introducing this feature, a keyboard should now be completely optional for day-to-day use.

Another new feature is support for badges that display icons in the gamelist view indicating favorite games, completed games, game-specific controllers etc. Note that these badges require support from the theme set. And on the topic of theme sets, a new theme named modern-DE has been included with the installation as an alternative to the default rbsimple-DE theme.

The scraper has been improved and expanded, and in addition to the previously supported media it can now scrape box back covers, title screens and physical media images (cartridges, diskettes, tapes, CD-ROMs etc.). These physical media images are also included in the generated miximages, although that can be disabled using a menu option.

As for supported platforms, v1.2 brings official support for the Raspberry Pi 4/400, both for the 32-bit (armv7l) and 64-bit (aarch64) versions of Raspberry Pi OS.

Apart from all the above, a huge amount of work has gone into fixing bugs, refactoring the code and optimizing for performance. The language standard has been increased from C++14 to C++17 and the built-in vector and matrix data types and functions have been replaced with the GLM (OpenGL Mathematics) library equivalents.

### Detailed list of changes

* Added alternative emulators support where additional emulators can be defined in es_systems.xml and be selected system-wide or per game via the user interface
* Populated the bundled es_systems.xml files with alternative emulator entries for most RetroArch cores
* Added a virtual keyboard, partly based on code from batocera-emulationstation

* (Windows) Launching a game that changed the screen resolution would offset the ES-DE application window when exiting
* (Windows) Enabling the option to hide the taskbar would sometimes not focus the application window on startup (possibly only an issue on Windows 8.1)
* If there were gamelist.xml entries for existing files whose extensions were not setup in es_systems.xml, these would still get loaded and displayed
* Fixed multiple minor rendering issues where graphics would be slightly cut off or incorrectly sized
* Under some circumstances ScrollableContainer (used for the game descriptions) would contain a partially rendered bottom line
* If the TextListComponent height was not evenly dividable by the font height + line spacing, a partial bottom row would get rendered
* The line spacing for TextListComponent was incorrectly calculated for some resolutions such as 2560x1440
* Fixed multiple issues with scaling of images which led to various inconsistencies and sometimes cut-off graphics
* The system time zone was not taken into consideration when using the Unix epoch which lead to various strange problems in the metadata editor

* There was some strange behavior in DateTimeEditComponent when changing the date all the way down to 1970-01-01
* When navigating menus, the separator lines and menu components did not align properly and moved up and down slightly
* Under some circumstances and at some screen resolutions, the last menu separator line would not get rendered (still an issue at extreme resolutions like 320x240)
* When scrolling in menus, pressing other buttons than "Up" or "Down" did not stop the scrolling which caused all sorts of weird behavior

* The launch screen text had ugly scaling artifacts if the menu opening effect was set to "Scale-up"
* The custom collection deletion screen had incorrect row heights when running at lower resolutions such as 1280x720
* If there was an abbreviated full system name for the "Gamelist on startup" option, that abbreviation would also get displayed when opening the selector window
* Really long theme set names would not get abbreviated in the UI settings menu, leading to a garbled "Theme set" setting row
* Disabling a collection while its gamelist was displayed would lead to a slide transition from a black screen if a gamelist on startup had been set
* When marking a game to not be counted in the metadata editor and the game was part of a custom collection, no collection disabling notification was displayed
* When running really low on texture memory, the menu texture would not get rendered correctly

* When the last row of a menu had its text color changed, this color was completely desaturated when navigating to a button below the list

## Version 1.1.0

**Release date:** 2021-08-10

### Release overview

The 1.1 release brings many large changes including a fullscreen media viewer, a game launch screen, a miximage generator, a new video player and a new controller API featuring automatic controller configuration and controller profiles.

A much better mechanism to find emulators and emulator cores has been implemented as well, which among other things removes the need to manually modify the Path variable on Windows to find RetroArch. It also eliminates the requirement for a separate Flatpak-specific es_systems.xml file on Linux.

There are also several changes under the hood, such as the addition of the CImg image processing library, automatic code formatting of the entire codebase using clang-format, change of language standard from C++11 to C++14 and lots of general code refactoring.

Apart from this, numerous small improvements and bug fixes are part of the release, as detailed below.

### Detailed list of changes

* Added a miximage generator that can be run automatically from the scraper and which includes comprehensive options, configurable from the menu
* Added an offline generator GUI for the miximage generator which can be used for bulk miximage generation without going via the scraper
* Added a fullscreen game media viewer
* Added a game launch screen that displays the marquee image, the game name and the system name
* Added a new video player based on FFmpeg
* Added a 60 FPS frame rate upscaler option to the video player which results in slightly smoother playback for low frame rate videos (e.g. 24 and 30 FPS)
* Implemented a new mechanism for locating emulators and cores, with configurable find rules (this eliminates some hacks such as the separate Flatpak es_systems.cfg file)
* Added a Windows-specific find rule that searches the Registry for the App Paths keys, which eliminates the need to modify the Path manually to find RetroArch
* Removed the deprecated %COREPATH% setting and corresponding menu entry
* The "Run in background (while game is launched)" option can now be enabled on all operating systems instead of only on Windows
* Added a workaround for a game launch issue on Windows when using AMD and Intel GPUs
* Moved to the SDL GameController API which gives numerous improvements to the controller handling
* Default controller configuration is now automatically applied, input configuration should rarely if ever be required any longer except for deliberate button customization
* Added support for selecting the controller type (Xbox, Xbox 360, PS4, PS5 and SNES), which changes the help icons, help text and the input configuration tool icons and text
* Added an option to limit the input in ES-DE to only the first controller (this does not affect the emulators)
* Switched the order of the "Back" and "Start" buttons (or equivalents) in the input configurator to align with the other button entries which go from left to right
* Added separate controller deadzone values for the triggers and thumbsticks
* Removed the startup notification regarding default keyboard mappings being in use, instead default mappings are now considered the recommended input configuration
* The controller input configuration is not automatically started any longer if there is no es_input.cfg file or if there are no applicable configuration entries in the file
* Increased the max allowed size for images when scraping, which should now only downscale files which really need it
* Changed the resampling algorithm for image downscaling for the scraper from bilinear to Lanczos which results in noticeably sharper images
* Added a configurable option to automatically retry scraping up to eight times in case of ScreenScraper TLS errors
* Changed the button for jumping to a random system or game and added a setting for enabling or disabling the functionality altogether
* The help text for the "A" button now shows "Enter" instead of "Launch" in the grouped custom collections view
* Added navigation sounds for some actions where it was missing, such as when attempting to add folders, placeholders or systems to custom collections
* Changed the custom collection "Jump to" navigation sound to the select sound instead of the scroll sound
* A notification is now displayed in the grouped custom collections view if a filter is applied to the selected collection
* Changed the default screensaver type from "dim" to "video" and made the fallback screensaver "dim" instead of "black"
* Moved the video screensaver audio setting to the sound settings menu
* Added support for the Nintendo Switch game system (using the Yuzu emulator)
* Added an option to use plain ASCII characters for the favorite, folder and tickmark symbols, which makes some themes with very pixelated fonts look coherent
* Created a new main menu entry for input device settings
* Moved the input device configuration tool to the input device settings menu
* Adjusted the size and position of the various menus to accomodate one additional entry on the screen
* The quit menu is now disabled by default, instead showing the "Quit EmulationStation" entry unless configured otherwise
* Removed the "Display game media from ROM directories" setting as it doesn't make sense to support this legacy functionality any longer
* Added support for using the %ESPATH% and %ROMPATH% variables in the slideshow screensaver custom image directory setting
* Improved scaling relative to the screen aspect ratio for various GUI components which enhances the layout on 4:3 displays and ultrawide monitors
* Removed the menu fade-in effect as it looked terrible
* Enabled the menu scale-up effect for the OpenGL ES renderer
* Renamed es_systems.cfg, es_settings.cfg and es_input.cfg to es_systems.xml, es_settings.xml and es_input.xml
* Changed the es_systems.xml logic so it loads from the program resources directory by default (a customized file can be placed in ~/.emulationstation/custom_systems)
* Added a %HIDEWINDOW% variable which can be used in the es_systems.xml file on Windows, primarily intended for hiding console windows when launching scripts
* Added support for using the %ESPATH% variable in the media directory setting
* Removed the marquee image from rbsimple-DE as it's now baked into the miximages
* Set the gamelist video scanline rendering option to disabled by default
* Changed the setting description for the favorites game toggling button
* Simplified and improved the setup of portable installations on Windows
* Converted all navigation sound files to stereo as previously it was a mix of mono and stereo files (done for rbsimple-DE and the fallback sounds)
* The themes and scripts directories are now automatically created during startup
* Cleaned up some application startup messages
* The application version is now saved to es_settings.xml, which can be used in the future to notify the user after upgrades to a newer release
* Added a DebugSkipInputLogging option which is intended primarily for development and needs to be manually set in es_settings.xml
* Added the CImg library as a Git subtree and created some utility functions for it (used by the miximage generator and the game launch screen)
* Added a function to ImageComponent to crop fully transparent areas around an image
* Added and clarified startup log warnings for missing or invalid es_systems.xml platform tags
* Added a CMake option to control whether the VLC video player should be built, and set this to off by default
* Made it possible to build on the Raspberry Pi 4 (tested on Raspberry Pi OS)
* Removed the deprecated VideoOmxComponent
* Removed the pointless APPLE_SKIP_INSTALL_LIBS CMake option
* Added a clang-format style configuration file to use for automatic code formatting
* Formatted the entire codebase using clang-format
* Integrated clang-tidy with CMake and made it possible to enable it via a flag
* Added the NanoSVG library as a proper Git subtree
* Changed the language standard from C++11 to C++14

### Bug fixes

* Marking all games as favorites for a system or folder or removing all favorite markings would sometimes crash the application
* Scraping new game media using the single-game scraper followed by a re-scrape that was aborted could crash the application
* The scraper search could be refined or skipped after the result was accepted which sometimes crashed the application
* Attempting to load a non-existent font file defined by the theme crashed the application instead of using the bundled font as fallback

* Scraper searches for Nintendo Family Computer (Famicom) games were not accurate
* The Quick System Select help prompt was shown even when there was only a single game system present
* The "Back (cancel)" help prompt was missing for the single-game scraper
* The "Y" button help prompt wasn't displayed correctly when using the Grid view style
* Fractional game rating values would always get rounded up

## Version 1.0.1

**Release date:** 2021-05-01

### Release overview

v1.0 maintenance release.

### Detailed list of changes

* Added support for the new RetroArch v1.9.2 default core directory location on macOS

### Bug fixes

* Fixed high DPI display support on macOS

## Version 1.0.0

**Release date:** 2021-04-20

### Release overview

First release, a major update to the application compared to the RetroPie version on which it is based. This includes new gamelist sorting logic, new game media handling and an updated Windows port as well as a macOS port. The menu system has also been completely overhauled and the scraper has been expanded to support multiple media types as well as providing detailed scraping configuration options.

Full navigation sound support has been implemented, and the metadata editor has seen a lot of updates including color coding of all changes done by the user and by the scraper. Favorite games can now also be sorted on top of the gamelists and game collections.

OpenGL GLSL shader support has been added (not for the OpenGL ES renderer though) and there are multiple effects implemented such as scanlines for videos, blurred background when opening menus etc.

A new default theme rbsimple-DE (based on Recalbox Multi) is bundled with the application and is part of the installation package/installer. Theme sets created for the RetroPie EmulationStation fork will still work.

Many bugs have been fixed, and numerous features that were only partially implemented or broken have been updated to a fully working state. The application runs much faster as well due to lots of optimizations.

### Detailed list of changes

* Initial version, fork from RetroPie EmulationStation 2.10.0rp-dev (master)

* Fixed an annoying gamelist issue that caused the game images and data to be updated and rendered up to six times every time the list was scrolled
* Not all input events were logged when running with debug logging activated
* Unknown command line options were silently accepted instead of halting the application startup and logging an error
* Added a sanity check to the --resolution flag to keep the resolution within reason (and to avoid crashes when making a typo for this parameter)
* Deleting a game from the metadata editor did not delete the game media files or its entry in the gamelist.xml file
* Hidden files still showed up if they had a gamelist.xml entry
* Fixed multiple instances of misaligned GUI elements on high-resolution displays due to the use of fixed-pixel constants

## Known issues

**The issues below are relevant for ES-DE v1.2.3**

* On Windows when using high DPI displays, if not running ES-DE on the primary monitor and the display where it runs does not have the same scaling percentage as the primary monitor, then the ES-DE resolution will not be properly set. The application will still work and if running in fullscreen mode it may not even be noticeable. This issue is probably caused by a bug in SDL where the primary display scaling is always used for calculating the display bounds. If using the same scaling percentage across all monitors, or if not using high DPI monitors at all, then this issue is not relevant.

* On Windows installing DS4Windows will break controller input in ES-DE for unknown reasons. Uninstalling this software should resolve the issue. On Windows 11 both DualShock 4 (PS4) and DualSense (PS5) controllers have been tested wired and via Bluetooth and both work fine in both ES-DE and RetroArch without any special drivers or configuration.

* On Windows the special characters &()^=;, can't be used in filenames executed by cmd.exe (applicable for the desktop, epic, kodi, ports and steam systems). This issue will be resolved with the 1.2.4 release.

* There could be problems with Chinese characters under some circumstances which may cause them to not get rendered properly in the gamelist view. This issue will be resolved with the 1.2.4 release.

* On macOS, the RetroArch setting "Start in Fullscreen mode" must be enabled or ES-DE will not be able to switch to the emulator window when a game is launched. Possibly it's the same issue with other emulators as well.

* On Raspberry Pi OS 10, Sony DualShock 4 controllers have problems with some button presses that don't register correctly. The issue appears resolved in Raspberry Pi OS 11.

* On Raspberry Pi OS 11 there are various graphics issues and sometimes the application or emulator completely freezes which requires a power cycle of the machine. This is seemingly due to GPU driver bugs and we can only wait for OS updates to address these problems. These issues have not been encountered on Raspberry Pi OS 10.

* On Fedora 35 a problem has been observed where the screen turns completely black or flickers intensely when starting ES-DE for the first time. A workaround for this is to simply exit the application with F4 or Alt+F4 and starting it again. Everything should then render correctly, and any subsequent startups will work fine including after suspending/resuming the computer. It's currently unclear if this is limited to only Intel GPU drivers or if it's a general issue under Fedora and/or Wayland. At least Wayland on Ubuntu 21.10 does not trigger the same issue.

* There is some screen tearing present on Unix/Linux which is especially visible during horizontal slide transitions. The problem exists on both x86 and ARM as well as on Intel, AMD and Nvidia GPUs and on the Broadcom VideoCore. The problem seems to be Xorg-related as tearing has not been observed when using Wayland, and it's not present on macOS or Windows either.

* Sometimes when RetroArch has been upgraded to a newer version, it apparently requires a startup to get properly initialized. When ES-DE starts RetroArch it always does so by passing some specific emulator core parameters, which does not seem to initialize RetroArch after such an upgrade. What happens in this case is that the RetroArch loading screen will be shown and then it will quit right back to ES-DE. If confirmed to be the case, this is not an ES-DE issue but a RetroArch issue and starting RetroArch separately once should fix the problem (at least until the next upgrade).

* There are problems with starting the standalone version of the PCSX2 PlayStation 2 emulator using some GPUs. What happens is that the emulator window does not get focused when launching a game which requires a manual Alt + Tab (or Command + Tab on macOS) to switch to the PCSX2 window. The RetroArch version of PCSX2 does not have this issue.
