• Deleting my current theme, installing and using "Airy"
• Reinstalling overtop of my current installation
• Tools > Download > Update Metadata for All Games
• Removing all music, manuals, videos, and images from my entire library, then downloaded only Box Front images
• Deleting all music and manual file paths from game metadata from the problematic categories
• Removed all custom sort titles from my entire library
• Checking the log file to see what Launchbox is doing while it is freezing up. (It's possible there's something helpful there, but I'm not seeing anything suspicious)
• Switching between WMP and FFmpeg video playback. Yes, I removed all media, but the log suggested that Launchbox was still looking for media to play, so I tried this just in case.
• Batch-converted all of the Box Front images into .jpg no larger than 900 x 900
• Windows Settings > System > Storage > Temporary files > "Remove files"
• Admin Command Prompt "sfc /SCANNOW" and "DISM /Online /Cleanup-Image /RestoreHealth"
• Win + R > "msdt.exe -id DeviceDiagnostic"

What should my next steps be? This issue has been going on for months and I don't have a trustworthy data backup to attempt to restore without rolling back a very very long time, so I would like to try other solutions first, if anyone has any ideas other than starting completely fresh?

(None of this was at all helpful. See my reply below for more details about the issue.)

Is there a way to search for the specific name of an imported rom? (The actual name of the Rar archive/Rom).

Especially when we are talking "Hacks", Roms can be named many different things.

An example : A smb1 hack named "Blink", Gets renamed "Wrath of the black mantra"; Took me ages to find out ?

具体的には上記の「エキサイトバイク」(PC-8801版)の画像なのですが、正常にダウンロードされボックス(フロント)に設定されているのにゲームリスト画面では表示されないようです。

こちらの環境特有の不具合なのかLaunchboxの不具合なのかは不明ですが、同じような状態の方はいらっしゃいますか？

また、解決方法がありましたら教えて下さい。

発生するバージョン：13.25 (ただし、以前のバージョンから発生し続けています)

よろしくお願いします。

I have let the system run for hours before and it just always sticks there.

I can run other things involving EMUMovies fine like the rom importer and auditing ect. Just always seems to be this where it sticks.

Any ideas?

I’ve been experiencing frequent crashes in LaunchBox ever since the FFmpeg update. I’ve been working on building out my setup, but the app has become increasingly unstable — especially since the official 13.24 release. While the recent betas seemed to reduce the frequency of crashes somewhat, the final release has made them more frequent again.

From a user’s perspective, the crashes seem to occur during various normal actions, but I don’t believe they’re necessarily caused by UI interactions themselves. Here are some examples of when the app has crashed (with no visible error message):

1. Editing a game record using the pencil button → Crash

2. Importing ROMs and clicking Next in the wizard → Crash

3. Selecting an existing game in any platform (UI starts to refresh) → Crash

4. Editing a game entry, making several changes or adding media, clicking OK to close the modal → Crash

5. Performing a bulk edit on multiple records, making a change, then clicking No when asked about further edits → Crash

I haven’t been capturing detailed logs or reproduction steps yet, as these have been happening during normal usage rather than intentional testing.

I’m happy to provide additional details, including my PC specs, logs, or to run more structured tests if needed. If this turns out to be an edge case, I’d like to understand why so I can fix it on my side. But if others are seeing similar behavior, I’d be glad to help narrow it down collaboratively.

For context, I’m a Software QA professional with 18 years of experience, so I’m familiar with structured debugging and root cause analysis. I’d be happy to coordinate with the LaunchBox QA team if that would help track down the issue.

If you have any initial theories or troubleshooting steps, please let me know and I’ll try them right away.

Thanks for your help!

There was the odd game for whatever reason would not display any border but after 2/11/2025 its the reverse and almost every game I import has no black borders.

Does anyone know how to fix?

Thanks

I've done some research and already know this is a bug due to having the option "Use all controllers" enabled. But... I would like to have that option enabled so Big Box can be navigated with any of my cabinet's joysticks... so what's the actual solution to this problem other than disabling that? Is this a confirmed Big Box bug? Does anyone know why this happens? If it is a bug, do we expect it to ever be fixed? Does anyone know any workarounds other than disabling that option? Just looking for some additional insight or suggestions.

The issue is that Big Box seems to randomly and inconsistently trigger anything that the joystick controls are configured to do.

For reference I'm using Big Box (LaunchBox version 13.12) on a custom cabinet running Windows 10 with four UltrStik 360 joysticks plugged in via USB. Also have a Mayflash GameCube adapter and occasionally some bluetooth Xbox controllers enabled. I'm using devreorder to force each device to load in a specified order so everything works nicely with RetroArch. Steam is installed but not running. Attract mode is disabled. All joysticks are aligned and in a dead zone. The problem occurs only in Big Box and only when Options > Controller > "Use all Controllers" is enabled.

I know this is BigBox and not Ultimarc, but I've found that whenever I have either (or both) of my Ultimarc 360 joysticks connected up, I get random Up/Down/Left/Right navigation in BigBox.

And it happens with either controller, even though I only have one of them selected in Options -> Controllers and I do not have "Use All Controllers" selected.

If I have the whole controller box disconnected, the random navigation does not happen, but it happens as soon as I have either one of them connected.  (Note that I can have my IPAC connected, and the random navigation only happens if I also have one of the Ultimarc 360s connected.

Any ideas?

The problem is that it doesn't accept any controller input, so when I eventually hit back (ESC), the action is cleared.

How do I fix this and get it to accept a controller input?

I know that BigBox sees the controller (joystick) because "Navigate Down" is set to "D-Pad Down, Left Stick Down" and it does the navigation when the joystick is pressed down.  But now, "Navigate Up" shows as "{None}".

Also, why does it use "Left Stick Up" when the controller is actually labeled "Ultimarc Ultra-Stick Player 1"?  

Thanks!

I'm running Launbox 13.26 on a Win 11 System. Hardware is MSI Claw Model A1M. 

I set up the system with 13.25 I think and a few month ago and I was able to set up most of the stuff until I run into an issue with MegaBezel shader's pack. I checked on my main pc if I made faults but there it worked.

This led me to trying to update shaders in Retroarch with the result of "unable to extract shaders.zip" error, or same error for any online updater stuff from RA.

So I checked for permission issues, but even that seemed to be ok. Always installed LB in c:/launchbox.

Reinstalling Retroarch into a new directroy also didn't help.  In that case c:/launchbox2.

Last resort, clean new Win 11 install. Said and done new OS installed and everything else up to date and set up. Installed LB again -> New Problem cannot download Retroarch.......

Next idea install RA from homepage worked, and I got it running. And hell yeah even online updater services worked. 

Buuuut Launchbox won't recognize the manual installation and also won't start associated games.

Kind of desperate right now because never experienced any of such behaviour on any of my other systems. (Which mostly had been Win 10 x64 systems)

So not quite sure what to test next...

Any ideas? 

Thanks in advance

Thank you.

Let me start by saying I LOVE LaunchBox!

The problem happens only when launching NES games using retroarch via LaunchBox.

With all other consoles when i double click a game it opens up retroarch full screen and ready to play.

With NES games when i double click a game, LaunchBox stays the top window and retroarch's launches the game and stays behind LaunchBox. so i then have to click with my mouse on the retroarch icon on my taskbar to bring the game window forward and start playing,

OR if i minimize the LaunchBox window after double clicking a game it will be full screen and ready to play (its like the game is launching behind LaunchBox)

So friggin' weird, its driving me crazy

Attached: Screenshot (I wrote in red bottom of pic)

I hope there is a way to fix this annoying issue. i don't know why ONLY on the NES console this happens.

Thanks to anyone who helps out

I've had this issue for a while where Launchbox tries to open and then closes. I try to open it, and I see it under processes in my Task Manager for a few seconds which then says "Suspended" before closing. Big Box still opens fine, but I don't know how to fix this problem with Launchbox. I assume this happened from a recent update and I trying reinstalling the latest update over my Launchbox location which unfortunately didn't work.

Quick Edit: This started happening after Update 13-17. Does anybody have a fix for this?

Disconnecting and reconnecting the controller resolves the issue, but only until the controller is used in another application. The order does not matter, i.e. if I connect a controller, launch a game in Dolphin, close Dolphin, and open Big Box, the controller does not work; if I connect a controller, open Big Box (controller works), launch a Steam game via Big Box, then close it and return to Big Box, the controller does not work. This issue does not impact any other applications, I can switch between RetroArch, PCSX2, Dolphin, and Steam and they all recognize and use the controller successfully. I haven't noticed any changes in the device description in the device list.

Also, to address some basic things I've already tried:

• Using a different gamepad: I had access to an old 3rd party USB Xbox360 controller, and it did not experience this issue. However, it's not practical for me to by a full set of new gamepads and configure them for all my other applications (assuming they'd even work)
• Using another of the same gamepad: This has the exact same issues. Including the same behavior of working until another application uses it. So if the first gamepad stops working, I can connect a second one and use it to launch one game, at which point it will also stop working in Big Box.
• Toggling controller related settings inside Big Box: I've toggled all three settings (use controllers, use all controllers, problematic controllers) to all of their various options, both before and after the issue arises, with and without restarting Big Box, as well as having two controllers in the non-working state and switching between them as the selected controller (all controllers: off). None of this helps
• DS4Windows: unfortunately not a good option for me since it breaks controller input for all of my RetroArch cores. RetroArch has an open issue on GitHub about it (#14063), but it doesn't look like it's moving much, although maybe I'll take a swing at it.

After writing all of this, I worry that this should have been a bug ticket rather than a troubleshooting request, but if anyone has ideas I'm happy to give them a shot.

If I run the same game standalone in Duckstation it loads achievements with no issues.

• I have disconnected and reconnected the Retroachievements login in both Duckstation and Launchbox settings. Generating new tokens each time. Username/Password is correct. It shows a successful login. 
• If I disconnect Launchbox from Retroachievements I still get the same issue.
• I'm running the latest Launchbox and Duckstation.
• Launchbox has no issues with any other emulator.

Please could someone help on what else could be causing this?

I'm hoping this is something really simple, I'm happy to look stupid here.

I recorded a video of the slow start time and the overall experience in the menus, is the startup time expected? 

every time I try to launch a ROM, I get multiple RAHasher.exe related errors. The rom will eventually open, but I’d like to avoid this going forward. 

im running an AMD Ryzen 7 x64 cpu

any advice?

I obtained the MAME 0.285 ROMs (merged) , copied it in separate folder from the one being tracked by bittorrent, and tried to import it via Launchbox v13.26 (on windows 10). After maybe 10 seconds of parsing, I'm getting this error: 

Quote

Name cannot begin with the '8' character, hexadecimal value 0x38. Line 4292731, position 47.

I tried to go into the MAME downloaded by Launchbox (which I confirmed is indeed v0.285 by runing mame.exe -version), and generated the catalog with mame.exe -listxml > list.xml

When I go to line 4292731, I see this, which doesn't seem invalid to me:

I also looked for any occurence of "<8" in the file, and found nothing, which means that file shouldn't have any tag whose name starts with the character '8'

The "Logs" directory of Launchbox is also emtpy, and I don't see any sneaky folder in the appdata.

In every youtube tutorial I found on this topic, the presenter doesn't go into details about this step. It's just a simply one-click, no trouble step with no mention of what could go wrong.

I may have missed, but didn't find any topic on this forum with that issue.

So I am rather confused as to what's going on. Anyone can help me? Launchbox looks like a really cool app, and it's a shame it immediately fails like this with a pretty cryptic error message and no hint as to how to fix it.

I would like to Sync my collection to the Cloud. I can enter my credentials and get a success message, but when I try to sync, I get the prompt to enter my credentials again...

What can I try to do?

Best regards

P.S. the download of metadata works ok, but the upload/sync of my collection does not work..

Is there a way to get Launchbox to display my "softcore" achievement points at the top, next to the hardcore ones?  I don't care about the hardcore ones really, but I do like getting random points for beating a level, etc.  Thanks a ton.

After it finished and the HHD light showed no activity, I closed LB, which closed on the screen leaving the "Welcome to Launchbox" prompt open, I checked task manage and here is what I got: Let sit and about another 10-15 minutes it all finally closed. Just reporting
