Sorry new to this forum so unsure if this is in the correct place. I’ve designed a tool which automatically loops through any folder of existing artwork you have such as box art, resizes and places that image or any number of images on a marquee template in whatever position you define and then saves the file as a marquee in the correct size for you in a chosen folder before moving on and doing the same for the next game.
First try in the week I generated over 300 Dreamcast marquees in just over a minute with a single click. Is there any hunger for this in this forum?
Some sample marquees attached. As for the look of the background template this could be anything you can design (not my strong point but maybe some here could make some good templates that we could overlay images onto through my tool at quick pace)
The beauty of this method is if you want to reposition the dreamcast logo for example or change the background colour its as simple as changing it once and pressing the button again (see examples where I've done exactly this in 30 seconds work)
