Cases for bulky cartridges (i.e. Wario Ware: Twisted!)

[thecpoc]

I was wondering what kind of case would best be suited for bulky game cartridges like "Wario Ware: Twisted!" or the "Game Boy Camera". It's not that I can't find any cases that'll fit these games so much that I can't close the cases. So the biggest concern, I suppose, would be to find a case that has a rather wide spine. Does anybody have any recommendations as to what particular case would be good for these types of cartridges?

Daroga made a guide for modding together two DS cases to house WarioWare Twisted.

Ah, cool. I guess it'll take a good amount of elbow grease, but it's good to know that a solution exists. Thanks for your help!

EDIT: Actually, I don't think I'll be using that guide. Unfortunately, I don't have the time to try and tackle on such an immense project. So I'll just go with my original plan of using a UGC for Wario Ware: Twisted. It'll require me to extensively modify the dimensions of the case art and whatnot, but that's a task that's much simpler than modding two DS cases together in that fashion.

Game Boy Camera is still a problem, though, but I guess I can just store it with the rest of my accessories and then I won't have to case it.
