Half dead screen, trying to recover data (device not showing in file explorer)

I have a somewhat old Samsung S7 Edge phone which (strangely enough) has only the lower half of the screen not working. This is, the whole screen lights up and displays everything, but ONLY the lower half is unresponsive to touching. As such, I cannot unlock it and turn usb debugging on. It is not rooted nor do I know how to do it; I don't really know a thing about coding. I have seen many previous threads and web pages about this, but at most I am very confused and don't want to brick it. It doesn't have any really important files, but very old GBA roms I would really like to keep, as well as some photos and pictures I may have. Any help appreciated!
