How exactly did you import? The wizard can import the files/rom set in several ways. DId you use the Full Set import option or just a selection of games? Also if the roms do not run directly in Mame without using LB that's the bigger issue. It is always best to set up the emulator first, test the games there, configure your controls, then do a LB import.

Yeah. You may be missing support files. Capcom games require a qsound zip file and there are other games that need specific bios/support files. So if the romset you downloaded did not come with those then that rom set is junk. Not sure where you got that set but I would get a rom set from a more reputable site. Google Pleasuredome Github io

Just tested a few random SF2 roms and it works fine. First thing, if you have to add any files to your zipped rom then you do not have a proper rom/rom set. It is best not do download random single rom files from sites as this is typically why users end up having to add files to a zip. Get a proper rom set so you ensure all your roms work with the version of Mame you are using. Also you should not import mame roms as a folder. If you are adding individual games you need to add the zip as Mame only works with zip file. Also if importing bootlegs or prototypes you need to uncheck those options in the image below (second pic).

Can you run the game directly in Mame without LB? If not that needs to be fixed. One thing to check is if you told Mame where your roms are stored. If you did not put them inside the rom folder within the Mame folder you need to update the Mame rom directory. If they do run directly in Mame you might have a setting issue in LB. One of the more common errors is the Associated Platform name. Edit your Mame emulator in LB and make sure in the Associated Platforms tab the EXACT name of the platform you imported to roms to is showing there. The name has to match.

TeknoParrot works perfectly fine with LB/BB. If you can launch it outside of LB then good chance LB can as well. Especially if it can be launched via command line. Here is a good write up on getting games from TeknoParrot added to LB.

In Tools > Manage >Emulators. Edit Retroarch and post a pic of the Details tab and the Associated Platforms tab. Also what is the Exact name you called the Neo Geo platform? As in what is the exact name it shows in the left hand pane in LB where your platform list is.

Make sure you do not have the option to "Extract Rom" checked. (Bottom right of image).

So looks like there should be an update when 12.8 is released (ETA unknown at this time) that might help with this. In short it is a corrupted image file. C-Beats mentioned typically we see issues like when the color profile metadata isn't stored correctly in the file but there are other causes. So some updates to help possibly deal with these types of corrupted color profile images that may pop-up.

I know one of our devs responded to a similar issue on our bitbucket site. I will check and see if there was anything discovered.

You can leave the media. Uncheck the media options and the import should match the LB game name to the media with the same name after import.

Yeah that’s why I recommend part of the name only.

Pretty easy to do. Just edit one of the games and delete the LB Database ID. Then type in part of the name. something like like just Comman, then the drop down box will list both of them and you can select the one you need.

Please use the "Request a Feature" option located at the top of the forum under "Help & Support". This allows us to track request and see users votes for it. Once you do so I would also post a link to it in your original post to drive other who may want the feature to vote. The more users that request a feature the better chance it has.

I do not know if someone may have made them on another site, but I know I have not seen them on ours or EmuMovies. Marquee image sizes are pretty scattered.

There really are not. There really is not set aspect for marquee images and those who recreate the originals from the actual arcade cabinet usually make them in the aspect the original artwork was in. You can use the Community Theme Creator to start creating your own marquee images in the exact size you need. The theme creator is also useful for creating custom images. Here is an example from Mr. Retro Lust. You can use his template and change the size to fit what you need.

I would recommend just adding a link to it in your original post. Just an FYI you can have other pdf files visible in Pause menu. If you have magazine scans, cheats/moves lists, or any other relative data in pdf format you can add them using the "Additional Applications" options in the edit game screens.

This is an issue I have never understood. Only 1 of my builds the marquee monitor needs to be on the right. My other 3 the screen can be in any position and they work fine. My main test/build cabinet has the marquee monitor position on the top and everything works fine.

Yes, you can control how the images transition from game to game as well. CTC is pretty user friendly if you do not know how to code. Y2guru has developed that tool a ton since he started it. Some more creative things though you might have to manually do behind the scenes, but for the most part his theme creator is pretty robust. Our youtube channel Faeren has regular streams with him using the tool to create themes and shows a lot of what it can do.
