There is no clue anywhere about this bundle... Was the outer box offered to you if you had bought both games? Or was the entire bundle given to you as a present somewhere? My guess is that it was offered to you in stores if you had bought Persona Batsu (Eternal Punishment) when it was released.
As for Chrono Memorial Box, the games inside are the same as their retail counterparts. If you have more information about it, please contact me!
