Kingdom Hearts would have been fun! I wish I owned a copy.
Here’s a game with a confusing last letter! It’s called Hamsterz: Hamster Feest! here in The Netherlands. However, the cart is simply labelled Hamsterz, and on of that the DS info calls it Hamsterz 2.
Hamsterz 2 is the international name. I bought it a couple of months ago because the menus look real neat.
