Yes, I can't please everyone : ) But you can sorta null those glare and dust through different methods. Either going in the lay files and removing them (which might take a long time), or dropping in some blank files.
There's also https://www.nintandbox.net/index.php/en/ for manuals and boxes and people retouch things there. I don't really know what to do about that side because as you just said, if they're all on the same page, it's not easy to read. But I can totally live without having any of this, though I'm working on case tops for the multi screen games
