Quick question to anyone who knows, how do trade evolutions work? Is there an Item or do I have to trade normally?

also hey, how do get riolu, if it even is in the game.

where do you get one?

Hey, so I am new to this entire thing, and I wanna try to collect every pokemon, so a really big question I have got to ask is how I can get pokemon like gengar. I don't know how to trade across emulators, so there's that.
