I've made a batch Marquee image generator that helps to quickly make large amounts of nice looking marquees. You can do 3 at a time for free: https://hammpro.com/ I do charge for more (sorry, still paying off school, but I hope my price is fair). The easiest way I found to do a bunch for LaunchBox users is upload images from your "Clear Logo", "Box - Front", and "Fanart - Background" background folders. HAMM will automatically match up all the images based on their file names and create marquees with the same file name. Then you can just drop the new marquees into your marquee folders. You don't need to have all 3 images, if you don't want a background or box, but you must use a logo.
Out put dimension is customizable, so this is great for users with the 1920 x 360 marquee displays, since there doesn't seem to be a whole lot of support.
Of course you don't need to use the LaunchBox image assets, you can provide all your own.
