Yes they can. I tried it myself. On version 2 a screen will popup before you connect. It will say "ver.1/ver.2" select version 1 and it will conect to your other tamagotchi. You don't have to do anything for version 1. It will work atomatic. Hope you have fun with your tamagotchi!
Yeah what Roar the Tiger said. Since the Nazorotchi is a secret character our V2 characters are secret because they don't show up in the V1 so instead of putting a character that dosen't exist they replaced it with a Nazorotchi.
