Nintendo has updated the demo games at its Wi-Fi enabled locations, meaning DS owners can now take their DS along to one and try out the likes of Dr Kawashima's Brain Training: How Old Is Your Brain?, Big Brain Academy, Clubhouse Games, Mario vs Donkey Kong 2: March of the Minis, Hotel Dusk: Room 215 and Elite Beat Agents.
You can also download extra items for Animal Crossing DS, as well as a special function for Nintendogs which lets you use bark mode without havng someone else physically there to play with.
