Mr Bill, many great DS games take a year between USA & UK releases, its very frustrating. I have bought the USA games from Play Asia & ebay with no problems. USA companies will generally not ship to the UK.
Major P, Hotel Dusk uses both screens too. And Trace Memory.
Of course you caannot use the wand on the top screen. If you get Animal Crossing, please PM me & we can arrange to visit each others towns.
