There shouldn't be any way the characters from the street fighter arcade go into candy rush, or pac-man, because neither the software or hardware are configured to transmit data. Yet because the plot demands it, they can through wires and stuff.
So, apparently, in the local where the arcades are located, the owner plugged a wifi antenna, or something, and because it shares the same multi-plug than the arcades, now Ralph and cia can walk into the wifi, and then jump into the internet. From a /g/ point of view, this is non-sense, but within the films rules, it's only logical.
This rises an interesting question: can these guys walk into any electronic plugged in the same multi-plug? Could they invade a vacuum cleaner, or an old plain cellphone?
