It looks like we might be moving to the states before next summer, but I'd like to give DS1 (5) a nintendo ds or something similar for Christmas. Does anyone know whether it would just be a matter of getting a new power pack if we moved? Are the games all universal? I've no idea where to even look to find out so thought I'd just beg mumsnet wisdom! I don't want to buy one if it will be redundant in 9 months! Thank you!
