If you imported the game into a Taito Type X platform make sure you set the "Scrape As" for the platform to "Taito Type X". This will bring it up. Normally all arcade boards are scraped as "Arcade". 

What you want is possible but would require a custom “Startup” theme. Startup themes can be coded to show various media and metadata. 
In our downloads section you can see some examples of existing Startup themes. 

Is that a Platform, Playlist, or Category? Depending on which then you need to file the image in the right spot. 
In the \Images\Platform Icons folder there is a specific folder for "Platform Categories", "Platforms, and "Playlists". Right click on Gun Games in LB and Edit. Top of the edit window will confirm what it is. It will either say Edit Platform Category, Edit Platform, or Edit Playlist. Then be sure to put the icon in the right folder.

It was a typo. Should be support@unbrokensoftware.com

Just tested and no issues from within the Xemu exe updating. You might have to download directly from the emulator site. LB does not have anything to do with that. It is not one of the emulator we manage with update notifications. 

Just to complete the thread for anyone who may have future questions...
No. If you do not link those storefronts in the Manage Storefronts settings in LB they would not show up. How could they? LB would not know you have any games from those store fronts to import. 
Nah, it's a truth. 

I deleted your other 2 posts about the issue. Please do not post the same issue multiple times. If you do not get an initial response to your first post just bump the post. 
Try force updating the Games DB Metadata. 
In LB >Tools >Download >Force Update Games Metadata

Yes, both in LB and BB there are controller mappings for this (BB even has a section for keyboard mappings). In LB it is the option for "Exit Game" and in BB it is the option for "Close Active Window". 
While you are in the options for LB I suggest taking time to look around in there at all the available options to further refine your LB settings. 

In LB: >Tools >Manage >Emulators and edit Mame. In the box with the Command Line remove only the portion below and see if that helped.

If the images are showing up in LB then try going into BB and refreshing the image cache. You will find the option to do this in the settings. 

If you are talking about in game play LB/BB has nothing to do with that. You set your in game controls in each emulator directly. 

Only issues would be launching the games to play if you are missing those dependencies.
You can import them for now just to get the games and media set up. You can always correct the emulator later.

Makes no difference. LB does not read anything when launching games to play. It sends a command line to Mame and tells it to launch the specified game. 

Just import the roms from where they are. You can either open a Windows folder where the roms are and drag and drop into LB to import or sell use the import rom/file option in the LB import wizard and it allows you to select the rom folder. 

This is correct. There is no option to hide the name. Small price to pay for not really having DRM on the software. 

You can just delete the other line in the Associated Platforms tab for Nintendo NES. Click on the cells and delete the contents. If you have Retroarch already set up to your liking no need to have LB do it. I do not use the automated feature for emulator downloads. Prefer to manually set all my emulators up. 

No. You currently need Windows or Android. 

There are different things going on here. 
1. The Unified themes (all versions) for the area left of the text list or wheel list uses images stored in image folders within the theme for the background, the video border, and the platforms clear logo that would be at the top. So you would need to add custom images. The image would be named after the platform and then placed in the corresponding image type folder located in \Launchbox\Themes\Unified & Ultrawide\Images\Theme\[Image Type]\
2. For any  box art/cart art (in your case the magazine cover) that would normally display in the area between the video and the game list on the right once you have added those images to the correct LB image folders be sure to go into BB settings and refresh the image cache. Typically those image would be located in \Launchbox\Images\[Platform Name]\[Image Type]\
3. The video within the frame you would need to add a custom video to the \Launchbox\Video\[Platform Name] folder. 

Yeah, the check boxes you reference are for metadata that would show up in the text details portion. Those new little windows I believe are a completely different line of code and would need to be manually edited.
