Animal Crossing will be improved over its Japanese counterpart, Nintendo announced today. The western version will allow classic NES title playback on the Gameboy Advance - the game will be saved in the GBA's flash memory until you switch it off. Enhanced support for the E-Card reader is also an added feature, with the special cards allowing secrets to be unlocked in the game. Both these features will require a link cable (and a Gameboy Advance, obviously).
