[Wreck-It Ralph] How can video game characters can be in two games at once?

For example, the arcade has Street Fighter and Marvel Vs. Capcom, Ryu participates in both games.

Is there duplicated characters? Does Ryu has to transfer from one fighting game to another as quickly as possible?

They're different Ryus. The Ryu from Street Fighter certainly has a lot in common with the MvC one, but they aren't the same.

What gets *really* complicated is when you hook up multiple copies of the *exact* same game in an arcade.
