Hard to say since I haven't played Re:Coded and I barely understand the summary/commentary you've been giving XD

Still, Digimon WERE considered creatures with feelings/emotions and personalities so I would argue they have a "heart." So that might help to understand how data!Sora makes sense. Their world was built from data from our world that took on a life of it's own...and it's probably a bit more complicated than that but I don't remember much about the explanation :Tb
