No crashes so far on Default theme and I think the background music stuttering is fixed. I noticed when I chose switch to Desktop mode, music was still playing until LB opened up after 2-3 minutes.

Current: -10 ms. Requested: 50 ms. 2025-09-19 12:04:35 PM Attract Mode stopped AI - Analysis What the errors mean (quick) ImageSourceConverter cannot convert from System.String Your theme (via CTC’s converters) is handing an invalid/empty string to an Image/ImageBrush Source. WPF then throws this first-chance exception repeatedly. COMMUNITY_Theme_Creator_Library.FileFallbackWithSearchConverter… NullReference The CTC converter got a null/empty binding value (e.g., missing art path) and didn’t guard it. Attract Mode stopped + FFME messages Attract mode is trying to show media; the bad image/video bindings blow up, so it bails and restarts. Fast isolation Switch theme: Big Box → Options → Views → Theme = Default. If errors stop, it’s 100% your custom theme/XAML or the CTC plugin. Disable Attract Mode (temporarily): Options → General → Attract Mode = Off. This reduces spam while you fix paths/bindings. Turn on “Show Missing Media Boxes” (or equivalent) to see which assets are missing on screen. Likely culprits (and fixes) Broken converter DLL: In your theme folder, …\BigBox\Themes\<YourTheme>\Plugins\COMMUNITY_Theme_Creator_Library.dll. • Replace it with the latest one from your Community Theme Creator install, or temporarily remove the plugin to see if errors stop (theme will fall back to simpler bindings). Bad/empty binding parameters in XAML: Look in Themes\<YourTheme>\Views\*.xaml for FileFallbackWithSearchConverter / FileSearchConverter. • Make sure ConverterParameter isn’t blank and tokens are valid (e.g., |ImagePath|, |ClearLogoPath|, |FanartPath|). • Guard nulls: where possible, wrap in a MultiBinding with a fallback or add TargetNullValue="" and use a Visibility toggle so the control doesn’t try to render a missing image. Invalid path strings: • Paths with illegal characters, trailing spaces, or wrong separators can trip WPF. Stick to absolute or well-formed relative URIs. • If you used string formats that concatenate folders/filenames, confirm they produce a real file path. ImageBrush vs Image gotcha: ImageBrush.ImageSource bindings are pickier. If your view uses brushes for backgrounds, ensure the bound value resolves to a valid URI (empty strings will cause the exact exception you’re seeing). Quick health checks in LaunchBox (no XAML edits) Tools → Options → Images: run Clean Up Images and Refresh Platform Wheel Images/Cache. Tools → Refresh All Images (rebuilds caches used by themes). Videos: switch the Video Engine (VLC ↔ WMP) to see if FFME plugin usage is the trigger; some themes embed FFME, others honor the global setting.

The glass, video and scanlines is not filling up the cabin can anyone let me know which code to update to fix this issue - 4K resolution? Also, this glass or overlay is not filling up the screen which is creating a vertical line affect on the far right of the whole screen. Would be great if this killer theme could be updated...

Is there a way to set the scraper to name my images and videos to the ROM name?

This script saved me so much time and labor... Is there anyway to prevent or suppress multiple messages such as these to keep the script processing without stopping.

You might want to try switching themes. I’ve noticed that LaunchBox runs much smoother and avoids crashes when using the Default Plus theme compared to heavier ones like Big Details 2.3, Omni, or Rincewind. Many BigBox themes seem outdated and could benefit from code optimization and better compatibility, so stability can vary. Recently, Vision 1.2 and City Hunter have been the most usable for me, though they still suffer from some lag and occasional crashes.

On 13.24.1 Beta, running Scan for Added/Removed ROMs on the Sony PSP platform never advances after adding ~2,000 .iso/.cso files it sits at “Searching for Sony PSP Roms…” for over an hour with no visible progress. If I delete the platform and re-import the same folder via the normal Import wizard, it completes successfully in less than 20 minutes, so the issue seems specific to the delta scan. I’m on Windows 11, default theme, debug logging is enabled and I can share logs. Is this a known issue or is there a fix/workaround to get the scan to complete faster or see progression without re-importing?

This is awesome! Keep it up and please share.

When updating MAME from version 0.278 to 0.279, the import process only brings in 4,602 ROMs regardless of whether “Skip All Prompts” is checked or unchecked. (Non-Merged Set, 24000+ roms in directory) I completely deleted my MAME platform and all auto-generated playlists before this test, so this was a fresh import. The same result occurs every time. Is this related to any other reports?

Is there anyway to hide the Splash screen when opening the app? Currently using it to display magazines and comics?

Can we get a copy to check out the work so far?

I’ve been using the Aetherial theme in BigBox and really like the overall style, but I’m hoping to modify it to resemble the ArtFlix theme from RetroBat/EmulationStation. I’m talking about that Netflix-style layout with the platform info on the left, a big background image or video behind everything, and the vertical platform logos lined up on the right or carousal. Right now, no matter which vertical wheel option I select, the wheel always stays on the left side. I’ve started digging into the PlatformHybrid1View.xaml file and have moved the platform wheel to the right but it's tiny or horizontal, but I’m still working on shifting everything else to match the ArtFlix look. I’ve cleaned up some tag issues along the way, so the layout loads without errors now. If anyone has tried something similar, or is familiar with tweaking XAML layouts in BigBox themes, I’d really appreciate some help or advice. Even better if someone wants to collaborate on building out a proper ArtFlix-style mod of the Aetherial theme. Let me know if you’re interested or have any pointers. Thanks! Many Thanks to @Faeran for a kickass theme.

That was the culprit. Thank you!

The new Aetherial theme still is non responsive when I select it as a main theme. I'm not sure if anyone else is experiencing this behavior. I have reinstalled it multiple times and just recently updated to the stable build with the same result.
