for those having trouble opening the box, here is how i opened the brain age 2 bundle with minimal damage
First of all make sure the BACK of the box is facing you, if you look from the top it should say nintendo ds lite, the wording should be reversed from the way you would normally read it
now, grab an exacto knife or something sharp, strell's wang perhaps, and start from the TOP left or TOP right side of the box (these corners should be where black meets red, a MINISCULE GAP should be visible) and take the knife/wang from one corner and cut it horizontally to the other corner, you can use a ruler to keep it straight if you'd like
keep in mind these are instructions for the brain age 2 bundle, i haven't yet received my zelda bundle, however it should be about the same
