I wonder if anyone makes any kind of case or container for protecting these things. I don't really obsess over protecting cd jewel cases or dvd cases for games on PS1, Saturn,PS2, etc, etc. because I can easily remove the insert, instructions and CD/DVD and put it into another case, but boxes for cartridge based games are unique and not so easily replaceable.
I've seen pictures of clear plastic containers for things like PS 1 games or Gameboy games, but not NES,SNES or N64 games.
I'd also like to know if I can these things cheap.
