Obviously, most of those covers were made before the Switch was a thing. I'm sure a Switch case would be a better solution, but I'm with Bear in that I prefer to use CD jewel cases for my games since they are closer to the originals. Unfortunately, there has never been a huge TG16 presence here, so you might not find anyone looking to covert the covers over, but you never know. You could always try to make some yourself which would be a great way to learn. The nice thing is that since some Switch covers have already been created, you at least have a template for the outer dimensions and the spine width. You could start with scaling down the DVD covers and see how that looks. If you do that, share them here. If they look good, they might take off and you might get more people interested. My PCE collection is too small for me to look into different case options. It's a system I love to play, but I don't enjoy buying for so I stick with the Everdrive.
