Devil May Cry 2 disc 1.
The comedians at my local used game shop like to split up 2 parters into multiple parts, they had disc 2 there last week and they've been holding onto Metal Gear Solid Disc 2 for a month now
andthey put Goldeneye: Rogue agent Disc 1 in a Harry Potter case, and disc 2 share its case with the Harry Potter game
They've also put PS2 games in GC cases and GC games in PS2 ones.
I've found 360 games in Wii cases, PS3 games in orig Xbox ones, PS1s in DC, DC in 360, etc, etc
