The primary reason I'm looking forward to LaunchBox 13.27. Plz đđ˝ get it right!
Steam Trailer Downloads!
https://www.launchbox-app.com/about/changelog
Â
Just to set expectations. When Steam overhauled their videos system and broke our Steam trailer download support, they basically made all of their video files not accessible. There's literally no videos on their servers for anyone to download anymore. Instead, they replaced it with live streaming versions of them. So, instead of files that can be downloaded, they are video and audio streams. This means the only solution we really had at that point was to capture the video and audio streams and use a program to mux them together and create a file to save to disk. Doing all of that cannot be realistically as fast as simply downloading a file, like we were able to do before, but it does work. All of it can be tested in beta right now, so let us know how you like it.

Beta 2 has been cooking for a while, but it's finally out for everyone to test. We mostly focused on Steam support, including importing and syncing your Steam library, with Steam artwork, trailers, and a bunch of import customization options. We also added a bunch of new platforms, emulators, and a bunch of fixes. Thanks everyone for the help with testing this as we get closer to release. Here's the full changelog:
- Added Steam game importing for the new Windows platform. This lets you bring your Steam library into LaunchBox for Android and launch supported games through compatible Android Windows launchers
- Added Steam media support. Steam games can now use Steam artwork and trailers, including box fronts, clear logos, backgrounds, and videos, giving imported Steam games better media coverage out of the box
- Added Steam library update support. LaunchBox can now compare your Windows/Steam platform against your Steam library to add newly owned games and optionally remove games you no longer own
- Added options to customize Steam imports. You can choose whether to import only games, include family-shared games, search the LaunchBox Games Database, prioritize Steam metadata, prioritize Steam media, or allow duplicate imports
- Added platforms: Windows, Arduboy, Sega Model 3, Uzebox, WASM-4, and Microsoft Xbox
- Added emulators: GameHub Lite, GameNative, Pizza Boy SC Pro, Azahar (Vanilla), Linkboy, Lynx.Emu, PICO-8: Android, PICO-8: Picpic, Aethersx2 (Turnip), SkyEmu, MelonDualDS, YabaSanshiro Pro, Vita3k (ikhoeyZX), Super3, X1 Box, aPS3e, and eka2l1
- Added RetroArch core mappings for Arduboy, Uzebox, and WASM-4. These platforms should now be easier to import and launch when using RetroArch
- Improved streaming video support. LaunchBox now handles more streaming video formats, including HLS streams, which helps Steam trailers and other online videos play more reliably
- Fixed Local and Cloud filters so games appear in the correct place. Games with local files now show under Local, while Cloud only shows games that exist only on a configured network/cloud location
- Fixed a possible crash when returning to LaunchBox. This could happen if notification or data services were not available yet when the app resumed
- Fixed possible image resize conflicts during media downloads. This could prevent media from failing or becoming inconsistent when multiple images were being processed at the same time
- Fixed scoped-storage handling for additional applications. Launching alternate versions or additional apps should now use the correct file path or URI
- Fixed scoped-storage lookup to use the selected application path. This helps when launching an additional app or alternate version instead of the main game file
- Fixed the built-in Vita3k Android emulator launch command

When viewing games in list view, the column headers are often missing. They come and go; the problem seems to be intermittent:Â
@JoeViking245Â helpfully pointed out that if you exit LB in boxes view, then restart LB, then switch to list view, the problem isn't there. But if you exit LB in list view, then restart in list view, the problem is there.Â
That's an old issue with the native WPF grid view system, which in essence is just a bad system overall. The next release will completely replace it with an entirely custom one, which should give us a lot more control over everything with the list view.

On beta 4. Still experiencing the Bigbox crashing silently after a while. Â
We will be tackling a larger overhaul next release, which hopefully that will help some for users.
4 hours ago, Gaming.Zone said:I am getting errors when attempting to use my favorite theme which is "unified redux".
- Updated to Beta 4.
- Opened Big Box and got an error.
- Switched to Default theme and restarted Big Box.
- No error on Default theme.
- Went to themes settings, repaired Unified redux, set as main theme.
- Validate Error returned.
Â

Notes: Additionally I changed my theme to unified refried and no errors. I uninstalled unified redux, rebooted big box, installed unified redux, applied as main theme. Still an error.
Consensus. 13.27beta4 does not like something on Unified Redux theme and causes the errors.When I see this happen, it's usually caused by some kind of bad file permissions issue that can usually be fixed with a restart. I'd love to get rid of themes that utilize those old and outdated (and really unneeded) files, but time is the limiting factor there.
4 hours ago, Gaming.Zone said:Something else I want to call out - but maybe it was just me. Â
When updating from beta3 to beta4 the system asked me if I wanted to upgrade, I said yes, and Launchbox shut down but I had to kill one of the processes after 10 minutes of nothing happening. So something may not be clearing correctly in beta3+ when initiating a shut down to install. I'll watch for the next beta or main version to update and can report on that as well. (Had no issues beta2 -> beta3.)The shutdown process is highly dependent on how much a user does during their session, but in essence there's a lot of files that go back and forth, and things can get stuck there sometimes that are almost always some kind of read/write issue. Basically, it's not a beta issue, it's more of a "LaunchBox needs to do these things and the computer is saying no silently and LaunchBox just keeps waiting for it to be done". The release after this one will better expose all the things LaunchBox does during a shutdown sequence, and provide ways out of a stuck process.

Thanks. Looks like it's due to using a controller. Fixed internally.
19 hours ago, Rlad said:Also 'scanning for additional roms' pops up even though Automatic imports is disabled.
Looks like this snuck through. While the option is off, it still runs a quick check on certain things, so we made it not run those checks now while the option is off.

4 hours ago, skizzosjt said:yea I've noticed and have previously communicated the same since FFMPEG was implemented. for me webm videos freeze up the frontend when they try to loop. I also have some mp4 videos that def came from emumovies that do the same thing. the kicker is these videos all play totally fine in FFMPEG if you use FFMPEG directly from Windows. it's only problematic how FFMPEG is implemented in Big Box and LaunchBox. for me view doesn't matter in Big Box, these freezes can happen on any view where a video exists.Â

2026-05-04T17:00:23.8764604-04:00 Big Box Shutdown: Final ShutdownBased on what's being read here is that the video file it was playing was slightly corrupt, in a way where the file is out of sync with its own start/end time. Basically it's reporting its time incorrectly and Big Box ends up using the incorrect time to make a decision and it locks Big Box. I tried with a few files, even attempted to corrupt one of my files but was unable to recreate this scenario. It was enough to attempt a fix, but I cannot test the fix. If either of you have a file where it's always doing this, send that, along with your data folder that represents all the settings you have when the issue happens, to me in a PM.

Thanks for this beta!
As noted by @Rlad, the auto-import wizard launches at startup whether or not it's checked in the options.
BUT if it's not checked, it doesn't seem to be âactuallyâ active! It's brief, and in my case, it doesn't detect a ROM that's been added.
On the other hand, if I check the option, it seems to perform a proper scan, detects the added ROM... and crashes for no apparent reason in that case.
See attached video.
And I didnât look into it (the crash) further because that wasnât the point. However, the added ROM was a different version (in another language) of a ROM that was already present. Maybe thatâs related?
As for the fanart backgrounds, I get the same crash as @Rlad when I try to view them in BB using the âView images fullscreenâ option. No problem in LB, though.
BUT I don't have this problem only with fanart backgrounds. Here is the log of an error that occurred with a Disc image, without any fanart background present :

As for FFmpeg, it still seems just as unstable to me, since LB shut down without an error message a few minutes after I switched to FFmpeg instead of WMP.
I haven't retested it in BB, but I imagine the problem must be the same.
Thanks anyway for this update!

I was unable to get this to happen, but I attempted a fix for the automatic ROM import combine ROMs situation, so we can hope that helps, and you can help test when it's out.
10 hours ago, bikeking8 said:Windows 11, v13.27 beta 4: I'm still having problems with the latest version during the import process, where it has the usual death spiral when it gets to "Refreshing Metadata - Validating Database"; it just never stops. Tried importing one game and I had to force close LB after 5 minutes. Just for reference, I've had LB since version 7 (love it), and I've only recently since last year had to keep the "Search for games in the local database" box unchecked to get around the hangups.
Based on what's happening during that step, that usually means there's some kind of "LaunchBox can't manipulate a file" issue due to all the normal reasons you can think of, like - another process is holding it hostage, or file permissions, or AV/security software.. etc. I made some changes to the process to try and simplify it as much as possible, but if the OS is telling LaunchBox that it doesn't have access to the file, it may not be enough. Sometimes Windows can get into a bad state and a restart of your computer could clear things like that.

Beta 4 is out with the following fixes:
- New Feature: Added Save Management maintenance tools to repair missing save metadata or clear and rebuild save metadata from emulator and vaulted saves
- Improvement: PCSX2 save matching now supports CHD disc images
- Improvement: Dolphin Wii save discovery and restore now support both disc saves and channel saves
- Improvement: 3D models now handle cached and fallback artwork more reliably
- Fixed: GOG media downloads now work reliably for icons, posters, and screenshots
- Fixed: Fullscreen image viewing no longer overlaps the taskbar and scales images correctly across image types, DPI, and monitors
- Fixed: Imports and media downloads now respect media limits more accurately, including no-limit automated imports
- Fixed: Game details videos no longer steal focus from the game grid
- Fixed: FFME video cleanup is more stable and less likely to hang or crash
- Fixed: Welcome wizard selections are saved more reliably when finishing setup
- Fixed: The bundled Xbox - White controller input pack no longer incorrectly reports that an update is available
- Fixed: The Manage Storefronts window no longer errors when using the Close button
- Fixed: Save Management now removes deleted save metadata immediately and more reliably, preventing stale saved-game and save-state badges from remaining after saves are deleted
Â
We are coming up to the end of the cycle and we are overall fairly happy with where we've landed. Thanks everyone for helping with this release cycle.
We've got more to come with a bunch of overhauled systems for the next release, and it should be a much larger one than this one. We spent quite a lot of time this cycle setting up new internal workflows to try and speed things while reducing risk at the same time, so hopefully the results will show off quickly with larger scoping changes coming out in faster succession than we were doing over the last few years.

Having an issue with the latest beta where Launchbox will crash during the import game process. I drag the game into Launchbox, get past the first couple of import windows but then it crashes and I have to force quit.
Edit: after a while it stopped doing it and has since worked. I'll continue to monitor the issue.
Thanks, let us know. I haven't been able to reproduce this. Usually when this is reported it's due to something on the user's computer conflicting with the wizard. The wizards are somewhat i/o heavy, so other things happening on the computer can trip it up sometimes.

Thanks, do you also have LaunchBox debug logs when this crash happened. Also, in that second report, there's that long link at the bottom of it which should lead you to the WER report. If you can attach that here as well, that would be super helpful.

This is being caused by the new video controls. They are pulling focus when a video starts playing. I have a fix internally that should help with that situation.

Hey LB team,
With the newest update, each time I try to import a new game, only the Screenshot - Game Title is imported, even when I have all the other media boxes checked. I have to go to each entry individually and download media for each one to get all the images.

Beta 3 is out with the following changes:
- New Feature: Big Box now includes a new "Show Playlist Actions" option for the game menu, giving you control over whether playlist actions appear in the game options menu
- New Feature: Local metadata package refreshes now use SHA-256 verification with retry handling and clearer staged progress, replacing the previous longer validation flow with a faster and more reliable process
- Improvement: Follow-up improvements for LaunchBox's in-app video playback controls (feature from beta 2) improve startup, resume behavior, fullscreen handoff, monitor targeting, and playback stability
- Improvement: Follow-up improvements for fullscreen image viewing (feature from beta 2) improve monitor targeting, fullscreen restore behavior, and general reliability
- Improvement: Follow-up improvements for the Welcome Wizard and other metadata refresh workflows (feature from beta 2) improve local metadata package refresh progress reporting, retry handling, and overall reliability
- Improvement: Follow-up improvements for Dolphin integration (feature introduced before beta 2 and expanded in beta 2) improve disc ID normalization and scan filtering for compatible additional apps and media types
- Improvement: Follow-up improvements for media previews and related media-heavy views (feature from beta 2) improve missing-media refresh behavior, local image preview support, and cleanup reliability
- Fixed: Follow-up fixes for Save Management (feature from beta 2) improve save deletion ownership, persisted save metadata cleanup, and batch metadata persistence
- Fixed: Follow-up fixes for LaunchBox and Big Box video playback behavior (feature from beta 2) resolve additional fullscreen restore, focus, and preview playback edge cases
- Fixed: Follow-up fixes for RetroAchievements filtering and navigation (feature from beta 2) resolve an issue where moving upward from the pause-screen filter could behave incorrectly
- Fixed: Follow-up fixes for Big Box details and theme behavior (feature from beta 2) address responsive layout issues in affected views and correct theme name display
Â
We are getting close to the end of the cycle. The remaining work will be centered on the remaining 5-10 fixes still left on our plate and all the hard work you guys are putting into helping uncover any other fixes that need addressing before release.
Thanks everyone for the help with the beta so farÂ

Most likely it's a beta thing (e.g. version numbering) that gets resolved with the official release. (@faeran?)
Installed ones will (pretty sure) always have the repair option available.Â
(Option "B" would be, if there's an issue with a particular integration plugin, tell you to close LB, delete the folder, then restart LB. This way it's "right at your fingertips".
)Â
Based on what I'm seeing in the images posted, things are looking fine, as they all show that the installed version is the latest plugin file. The way it works is that the app itself comes with newer versions of the plugins than what the server has, so in the screenshots it shows having version 1.1 installed but the server only currently has 1.0 available. It basically means at some point before the beta is done we will need to update the plugins on the server. The logic most likely says something like "if versions don't match, assume it means there's an update", which is causing the update button to be clickable, but if you attempt to update we will most likely overwrite to the newer version during app startup. So, definitely some UX to improve there in the future to help with some confusion.

As of beta 2 BigBox still crashes with the exception code 0xc0000374 in ntdll.dll after a short period of time in screensaver or attract mode.
I tried every new version since 13.24 .

In version 13.23 everything is fine, so that's were i go back to every time.
I also tried a complete new install with only a view games and it crashed too.
Same problem on my second pc.

If you can, check your event viewer. There may be one or two full crash reports, also including a Wer report txt file that you can send that could help narrow down what exactly is going on with your specific computer.

Has anybody found a solution to this? This is happening to me as well
Â
Â
The original error is essentially saying that something on the computer, whether it be Microsoft Defender or another security software has blocked that dll file, which is a requirement to run LaunchBox.
The way out of that is to identify which software on your computer is blocking dll files inside of the LaunchBox folder and get it to stop doing that.
Once you do that, if you are unable to recover the dll files that the software quarantined or deleted, you'll have to then re-install LaunchBox from the setup file. Run the setup file, making sure you install it in the exact location as your current install (making sure it doesn't add an extra "LaunchBox" folder to the install path), and getting to the end of the installer. Once done, LaunchBox should open up, and if you had a library of games, you would see them once again.

Hi. Great update! Im really enjoying the Retroachievements enhancements. Two minor BigBox requests: 1) allow wrap around from the top of the achievement list to the bottom (currently, it only works from bottom to top) in the pop out window and 2) allow a controller button press to fill in the verification box when trying to view an achievement from the Retroachievements website (currently, I cant get past this). Thanks.Â
1. Good suggestion - I'll add that to beta 3
2. I do have a plan to address this, but the reason it's doing this is because we utilize our own chromium browser to load up those pages, and for some reason that chromium browser doesn't have a more modern way of handling that page unless you use a mouse (which does work, but who is using a mouse in Big Box?). So the fix is really a much larger change away from Chromium across the app, and filling in the holes it leaves with a better approach. I already started working on that, but that won't make it in until the release after this one.

I have a new issue to report: Ctrl-A to select all games in LB no longer works since version 13.27 beta 2.
Correction: It works, BUT only under certain conditions. If I press CTRL-A after selecting a game, nothing happens!
If I left-click on that game againânot too close, so as not to launch itâCTRL-A works afterward.
The same goes if I want to select another game from my list by typing a letter.
Or delete one with DEL.
Thereâs an older issue thatâs been present for quite a few versions now, but which I hadnât reported.
Selecting âtext-list with detailsâ from another view in BB doesnât work with the 3-DIMENSIONS theme.
I have to switch themes and then switch back to this one, as shown in the video.
Otherwise, I can also confirm that Iâve encountered these two bugs reported by @Rlad:
- The three menusâManage Themes, Startup, and Pause Themesâare empty.
- Related Games is only showing artwork from the database, not local files.Thanks for your work anyway! đđ

40 minutes ago, kobaturtle said:Video control is a great new feature! Thanks!
Since new Beta, I lost the ability to type/navigate/find a game name directly from keyboard input in launchbox main menu. Until now, typing letters was easy way to navigate through game titles
Thanks guys, What's actually happening here in LaunchBox is that the video control UI is pulling focus from the image grid, which explains things like, keyboard navigation stops working, jumping to game by typing, and anything requiring the image grid to stay focused, stop working in certain situations. I've fixed this internally and it'll make it into beta 3.
As far as the 3-DIMENSIONS issue, this one is a bit of a mystery. I ran some quick tests but am not seeing what you are seeing. You may want to delete the theme and redownload and see if that helps. I'm also thinking maybe there's some Options or theme specific options that could be getting in the way there, but that's more of a high level thought than anything else.

This one I'm also not seeing, in that I checked a number of those platforms but their Achievements show fine. All I can do is talk about the troubleshooting basics. Make sure you are logged in and provided the API, go into Tools > Options > Integrations > RetroAchievements and you should get a green check mark to confirm that your API key is good. Make sure you've run the achievement scan on the games under Tools > Achievements. Then make sure you are using the Default theme, or a theme that does show the achievements within the Game Details pane. Make sure the Achievement badge is enabled. Things like that.
At this point, I've got about 12-ish things ready to go for beta 3, with another handful I still need to tackle over the next few days. But if all things go well, we should have another beta by the end of the week or beginning of next.-

Hey all,
Beta 2 is finally out! This one is pretty packed, with a lot of moving parts across major areas like RetroAchievements, Save Management, imports, and Big Box behavior. Because of how much has changed, there is a higher chance of edge cases or regressions, so we could really use as much testing coverage as possible. If you are not interested in testing or just want a stable experience, it may be best to hold off on this one for now, but for those jumping in, we really appreciate the extra eyes and feedback.
Â
 â ď¸Â As of Beta 2: For those who heavily utilized the save backup features in previous versions, please refer to this migration guide carefully before upgrading to this beta. There have been some structural changes that affect how saves are managed. This guide talks you though everything you need to know. â ď¸
https://feedback.launchbox.gg/help/articles/5615549-1327-save-management-migration-guideÂ
Here is what we could use help testing.
- RetroAchievements received a major expansion across LaunchBox and Big Box - While signed into RetroAchievements, browse Game Details, achievement profile views, pause screens, and default Big Box views to confirm beaten/mastered status, playtime commitment details, filters, and related stats all load and behave as expected
- Save Management has been significantly expanded - Test save tracking, backups, backup history, and restore workflows with supported Dolphin and PCSX2 games, and verify RetroArch Saturn saves continue to be detected and grouped correctly
- The Welcome Wizard import flow has been overhauled - Run through a fresh wizard import and pay attention to staged progress, status messaging, retry behavior, media download limits, and persistent image download queue handling
- Xbox 360 and PS3 now support additional formats - For Xbox, try importing default.xex and Games on Demand titles - For PS3, try importing ISO files - and confirm game detection, naming, and import results make sense
- Steam trailer downloads have been restored and LaunchBox video playback has been updated - Download trailers for a few Steam games, then verify playback controls and general in-app video behavior work as expected
- Import and metadata workflows saw several targeted updates - If you use Ubisoft, Xbox storefront imports, or mixed-ROM imports with multiple versions and regions, those are all good areas to sanity check in this beta
- Big Box received several quality-of-life and stability updates - Hybrid view searching, achievement filters, popup behavior, system menus, and video playback are all worth extra testing time if you use Big Box regularly
Here is the full changelog.
- New Feature: LaunchBox and Big Box now include major RetroAchievements expansions with richer Game Details support, beaten/mastered and playtime commitment visibility, improved achievement profile stats, improved Dolphin integration, and broader default theme support
- New Feature: RetroAchievements can now be filtered in Big Box and Pause views, making it easier to browse and focus on the achievements you care about
- New Feature: Big Box Hybrid views now have their own dedicated search behavior, keeping searches scoped to the current platform or playlist instead of kicking you out to a global search
- New Feature: Save Management has been significantly expanded with better save tracking, automatic backups, backup-on-close options, backup limits, manual backup scans, and save version history tools, including expanded support for Dolphin and PCSX2 save tracking across Nintendo GameCube, Nintendo Wii, Nintendo WiiWare, and Sony Playstation 2, plus better support for the Mednafen Saturn core
- New Feature: The Welcome Wizard import experience has been overhauled with staged progress, clearer status messaging, improved retry handling, and much better visibility into what LaunchBox is doing during first-time imports
- New Feature: The Welcome Wizard now supports media download limits and persistent image download queues, giving you more control over setup-time media downloads
- New Feature: LaunchBox now includes video playback controls for a better in-app video viewing experience
- New Feature: Manage Emulators now includes an "Open Emulator" context menu option for quickly launching the selected emulator directly from the list
- Improvement: Ubisoft imports have been refined with better product filtering, name cleanup, and settings handling for a more reliable import experience
- Improvement: Xbox storefront importing has seen some reliability improvements with lookups, caching, and import handling
- Improvement: Xbox 360 imports now support default.xex and Games on Demand formats across all import workflows
- Improvement: PlayStation 3 imports now support ISO files across import workflows
- Improvement: Fullscreen image viewing has been improved with pixel-perfect integer scaling, image detail labels, and better fullscreen monitor behavior
- Improvement: Related Games and Game Details performance have been improved by deferring expensive loading until needed
- Improvement: 3D model viewing, carousel browsing, and media list performance have been improved for smoother browsing in media-heavy views

Clear Logos are not downloading on auto import, and also not when selecting Update Metadata and Media for Selected Games. I've ensured all clear logo boxes are checked, I've also tried toggling them off and on. Clear logos successfully auto download when importing games manually, and I'm able to download them by editing manually and hitting download media. I've had this issue for a few months now, not sure when it started.
That's an odd behavior. I know that for automatic ROM downloads the media options are found under Tools > Options > Media > Automatic Imports Media
So, you'll want to make sure those options are set properly to your liking.
I few moments ago I just ran a few imports and specifically downloaded some clear logos during them. Can you give some examples of platforms your importing and which regional games you usually have in your sets? -

So. I did reset my pc and everything is working as it should. Thank you for the reply. I do have a new issue though when exiting the dolphin emulator from bigbox my wiimotes will not turn off. I tested this with just lauching dolphin and exiting and the wiimotes turn off. Why would bigbox hang up the wiimotes from turning off?
Not really sure. There's not anything in Big Box itself that would hang onto it. It's possible it has to do with how Dolphin is opening, or more likely how Dolphin is closing. You may want to take a closer look at how you are closing Dolphin when you open it from Big Box.

Thanks to all you guys we released Beta 5 with all the issues we were able to reproduce. Some we just took a stab at since we were unable to recreate them (like processes being stuck), so if you were having issues, take a look at the changelog to see if there was an attempt on solving your issue and test it out and report back. At this point we've scheduled the release for next week, so let's hope we make it!
Here's the changelog for beta 5:
