I've looked all over online and can't find an answer, so I figure somebody here might know the answer.
As I've said, been playing around with Disney Infinity 3.0. I know that the character data is obviously already in the game itself, meaning that putting the figure on the portal just "activates" it for use in the game.
But how does the Expansion Packs work? Is the Toy Box Takeover and Speedway expansion (as well as others) data already on the game disc, or is there more than an NFC chip in those hunks of plastic? Is there an executable "program" or something similar contained in the expansion pieces that utilizes assets on the game disc? I guess what I'm looking to have answered in the technical aspects of it.
It's not really a big deal, but I like to know how things work so it's been bugging me. Everywhere I look online, it pretty much just directs me to the same Disney website or a fan site that says "Pop this piece on the portal and you too can play the Toy Box Takeover!" or something similar.
