Hey guys. A few of my games have the cases busted. Mostly on the from "door" or the back wall. Are the cases any different than regular CD cases? I noticed a small "NTSC Compact Disc Audio" in a small square or something on one or two of my cases (on the inside disk tray), but I'm thinking those are probably replacements put on by someone who owned the game before me. On the off chance that those are the official ones, where can I find those?

Othewise, will it hurt the value of my games to replace them with newly bought cases? Say, these; Amazon.com: Memorex CD/DVD Jewel Cases with Clear Tray 10 pack (Discontinued by Manufacturer): Electronics
