System Menu < Options < General < Skip Game Details Screen
But this way you'll never see the Game Details screen unless you change it back.
Instead, you could also map a button or key to "Play" the selected game (skipping the Game Details).
System Menu < Options < Controller Mappings < Play

According to some recent posts on LaunchBox Discord and a 2 year old post on LaunchBox reddit, you need to add the games to 3dSen itself, 1st. 
It then saves game info into a rom.json file.  Located somewhere in [%appdata%\..\LocalLow\Geod Studio\3dSen]
After the games have been added, open the json file with any text editor.  An example node looks like:
"id": "64", "romPath": "C:\Nintendo NES (3dSen) Games\\Mega Man 3 (USA).nes", "title": "Mega Man 3", "lastTime": 1692883659 Look for the game and get the id number.  Edit that game [that you've already imported into LaunchBox] and in the Emulation section, it should already be set to use your 3dSen emulator [that you've already installed into LaunchBox].  Check the box for Use Custom Command-line and in the box below it, put in -id=64  where "64" the id number you found.  Save. Close. Play
Yes. You'll have to do it individually, for each game.
 
For me, this is all hearsay.  But @ci2own says it works.   

Without overthinking it...
$Esc:: { WinClose, ahk_exe {{{StartupEXE}}} Sleep, 5000 WinClose, ahk_exe {{{StartupEXE}}} }  

You're not blind.  Or... we both are.  
Depending on what you wired the Mute/Unmute button to and what mode it's in, you might be able to create an AutoHotkey script that you have run when you start LaunchBox and/or Big Box. For this (possible) option to work, you need to know what your button is mapped to.
Example: Your encoder in keyboard mode and you have the button mapped to "M" (again, just an example).  The script would look like
m::Send {Volume_Mute}  
 
To use the built Pause Screen, set the pause button.  Note: LB and BB require separate mappings.
LaunchBox:   
Keyboard Mode:  Tools < Options < Gameplay < Game Pause XInput Mode:   Tools < Options < GameControllers < Mappings - Show Pause Screen Big Box:   
Keyboard Mode:   System Menu < Options < Keyboard Mappings - Show Pause Screen XInput Mode:   System Menu < Options < Controller Mappings < Show Pause Screen  
Once that's all dialed in, take a look around at all the other cool things you can do from within the Options Menu(s).  

In your \LaunchBox\Images\Media Packs\Platform Clear Logos\Nostalgic Platform Clear Logos\Playlists\ folder, for your example image, what is the file name?
Nintendo 64 Fighting.png Fighting.png (Green is good. Red is bad.)
 

LaunchBox doesn't natively import MAME's softlists.  That said, (some/most/all) softlist BIOS and Device files are in with the MAME full Arcade set. (just not the softlist game ROMs)
If you use the MAME Arcade Full Set Import Wizard, on one of the screens is a list of items to check/un-check.  One of them is Skip Games Unplayable in MAME (or similar).  Unchecking that will import the miscellaneous file you're [most likely] seeing.
If you don't want to reimport, you can click the filter icon (when in your Arcade platform) and select Genre - System - BIOS and delete the resulting files.  Do the same with Genre -System - Device.
I say "delete" (in LaunchBox, that is) because they do you no good and you can't play them anyway.  If you want to "Hide" them instead, select All of the above resulting filtered files and press Ctrl+E to start the Bulk Edit Wizard.  Then select Hide and set it to true (or however it's deemed).

Just tested. No luck.  Force updated the local database, then all 4 were found.

Yes.  Easiest way is to right-click the Arcade platform and click Delete.  When it asks to delete Images (2nd popup), click no.  Move all (the rest of..) the files (and chd folders) into /Games/Arcade/.  Then run the Arcade Full Set Import Wizard (and it won't ask if you want to move the files. ).

For Steam, last I read you can add the parameter -silent.  Whether it's still valid in 2025, not sure.
For apps that just hang out in the background waiting to be used/triggered, you should be able to:
Create a shortcut to the app Right-click the shortcut and select Properties Next to Run: change it to Minimized Click OK to save Then point your Startup to the Shortcut  
No. Not really.  If you do see a performance boost by running it shelled, you're probably running your system near it's limits already.
The main benefit I see is that it's just plain cool to turn on your cab and have Big Box do its thing.  
I personally don't use the shell feature because I'm OK with clicking an icon on the task bar.  Also, I'm periodically making changes (emulator or game or writing a new plugin) and need direct access back to LaunchBox or Windows.
 
Hopefully someone else will chime in on this one.  I've never used the Big Box shell feature.

No idea what "SW and MC" and "SW,ESB" are.  If they're arcade machines, check if there's a "SW and MC".ini file or "SW,ESB".ini file.  Of course, replace you acronyms with the ROMs' name. 
Or look for an ini file named after those machines BIOS name or parent system.
If the machines use the same monitor type atypical to most games, look for their monitor type .ini file (vector, raster, lcd...)
Whatever may be in those would override what's in mame.ini.

There's an article in the LaunchBox Strategy Guide regarding the Media Packs.
See here: LaunchBox Media Pack Feature – Version 13.21 - LaunchBox

If anything, it would make it "slower".  You've essentially added 4 additional fields that it now has to parse through as well.  However, my guess is it'll search the main Title first, then the alternate names [if there wasn't a hit in the main title].  Making the alternate title(s) a moot point [in this example].  (IF my guess is correct)
Now... say, if you rename the games' Title to "My Favorite Game", it would probably be nice to have those alternate names available.  ("I renamed the game to something really cool but forgot what I called it. But I know it had the game "Doodle" in it.")
 
That all said, searching happens pretty dang fast.  I think you'll spend way more time adding in the alternate titles than you could ever collectively save waiting for search results.

I'm believe Default Plus was the 1st theme to implement the platform icons feature. So it had placed them into it's own folder structure.  Subsequently a 'universal' folder was added to store those images.
If you wish to have those icons available for all your Themes (i.e. themes other than just Default Plus), they can be placed in:
\LaunchBox\Images\Platform Icons\Platforms\
Note: As a fallback, Default Plus will also look for icon images in this folder if a particular one doesn't exist within its own folder structure.

Did any of the other platform versions/ports show up with just "Shantae"?
 
I just tried it, and it was found here.  This is what I did:
Clicked on the Nintendo Game Boy Advance platform went to Tools < Import < Manually Add Game... (actually I just pressed Ctrl+N. Same thing). typed in "Shantae" (without quotes) and pressed Enter 
 

It does. But I thought you already put the BIOS (neogeo.zip) into the same folder as the ROMs.  And make sure you're still working with SNK NeoGeo Carts and not SNK NeoGeo CD.
Also, in most cases, you don't need to have the media type (i.e. -cart) in the command-line parameters.  So here you could have just:
-rompath %romlocation% neogeo  
For [future] Reference:
Go here:     http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=neogeo
Scroll down to  and click on SHOW...
That'll show what files are required for that system.
 
Save the above link, change just the last part (neogeo) to the system you're working on next.  (32x, neocd, etc.)

Off hand, my guess is the [extra] period you have between unmute and bigbox.  You can try putting the entire parameter "within quotes" (just like you have in the batch file). Or try removing that dot ('period').   But NOT the dot before ahk.
 
If you end up going this route, create a shortcut to the batch file.  Right click the shortcut and select Properties.  Next to "Run", change it to Minimized.  Click OK to save and close.  Then point to the shortcut.
 

Could it be you have Exit Game mapped in LaunchBox?   (Tools < Options < GameControllers < Mappings)
Or if in Big Box, Close the Active Window. (System Menu <  Options < Controller Mappings)

The error indicates something is up with your license file. Email support@unbrokensoftware.com and they can sort it out for you.
Anytime an error code like that is tossed it's one of three situations:
1. The license is banned
2. The license has been altered (you tried to change details in the file, or the file has been corrupted).
3. You are using an Android license on PC or vice versa

Not that I've seen.  You can have custom Startup screens per platform within your selected Startup Theme. But not for Shutdown screens.
You can however customize the Shutdown screen (change it up to your liking) in your selected Theme. But is still a one-Shutdown-screen for all platforms.

It's because in v1 you could set the index. Which really shouldn't be done. That's why Jayjay removed it in v2.

That plugin's been broken since LaunchBox v13.19.  However, it will still work in LB v13.18 and older
Due to lack of interest noted on its download and support pages, the author hasn't deemed it worthwhile to take the time to update it.  Or rather, do a near complete rewrite to make it work again.
Fortunately, the list of ROMs Demul can run is relatively short and can be obtained by running "demul.exe –listroms" at the Windows command prompt.

What happens is, when a theme makes a call to a specific View (i.e. the Music Notification popup) and that view doesn't exist, Big Box will look for it in the Default themes' folder. (it's like magic )
I suspect if, instead of replacing the KeyboardView.xaml file, if you simply removed it from the /Critical Zone - BlueBox/Views/ folder, it would work [as well].  Maybe.  However, replacing it with one that's known to work is probably the safest bet.  
Well done on using your resources at hand!

I didn't know that games could be launched via a URL.  Not that I know, ya. It makes sense.  
 
What it does when you click "the button" (v1.1.0😞
Scans all games in the selected platform If the games' Application Path is a shortcut (.lnk) or a weblink shortcut (.url) If the shortcut file exists The game is marked as Installed (Installed = true) If the shortcut file does NOT exist The game is marked as Un-Installed (Installed = false) ScanForUninstalled (v1.1.0).7z

Force update the metadata file.

Using Custom platform icon images is not available in the free version.
If you decide to get a premium license, then it's simply a matter of placing the image files in your /LaunchBox/Images/Platform Icons/Platforms/ folder.
