How do you evolve Porygon in this? And is Porygon-Z in this? If so, how do you evolve Porygon2?
There's an item called Evo Stone it acts as an evolutionary stone for all Pokemon that normally evolve via trade. It evolves Porygon into Porygon2 and Porygon2 into Porygon-Z.

You get one for free from a guy in Elder Village (check the southwesternmost house). You can also buy Evo Stone's from the Green Pokemart dude in Nahara Town.
