I'm not familiar enough with Nintendo consoles to know what typical things are different in their releases but I suspect that a difference is present but we just do not know what it is. Firstly because the one example is just a box and foam, and secondly we do not know to what degree any peicemealing has been done. It is possible that each have included something different inside. Maybe a manual change, or a change to the plastic wrap that holds a part, or a change to the foam, or where a paper item is printed, etc. Also I do not know if there are any instances where a NES came inside of an outer packaging, either an outer box or a sleeve. I ran into many boxed PS2 consoles that were just inner boxes from packs that were not released in that way on their own. They are still added to the db in any case.
