I found a 10 pack of white dvd cases on Amazon for $8.88 shipped. Ordered those, hopefully they're decent quality.
There are eBay sellers that have genuine game cases for sale... I think one was called BRE Software.
Anyone ever notice how much Arch Rivals is like NBA Jam?
Yeah, it's like they were developed by the same company!
Edit: In case anyone notices I'm not around as often, I hurt my neck while uh... stretching yesterday morning. I can't turn all the way to the right so I'm hurting right now. ;_;
