If I change the date on my ds it says: "The DS internal clock has been altered, blah blah . . . like to sync game carts time tim match that of your ds?" If you say yes then it says: "the clocks have been syncronized, please wait 24 hours to migrate pokemon". If you say no it just exits . . . I might be able to migrate on my brothers DS . . . if I can sneak it out of his room (its 3am here). BRB, wish me luck and stealth :P
