Number of copies : ???
The origins of the bundle remains obscure, even now.
Some say the "not for sale" outer box was available as a gift during the Jump Festa in 1999 when you bought Chrono Trigger, some say it was a pre-order privilege item but there is no clear information about when or where it was distributed.
So I decided to post it both in "Softwares given in special events or specific places" and "Campaign edition" sections.
The box is made to contain both commercial versions of Chrono Trigger and Chrono Cross.
