Most of my loose carts are stacked on my game shelves. Discs are much easier to deal with, however. I've bought a few games on disc that were missing the artwork, so I downloaded replacements from cdcovers.cc and printed them out. Most are pretty common games (Marvel vs. Capcom 2 [DC] being my only valuable game with a printed insert), so I just printed them out on regular printer paper and cut it to fit a dvd or jewel case. You can tell pretty easily when you pull it off the shelf, but stacked up with everything else it's hard to notice.
