Same way you did with Platinum, Diamond, and Pearl, have fire red in the GBA game slot and select migrate from Firered....
It can connect to pokemon battle revolution.
no
No. You can only transfer firered Pokemon to soul silver.
yes if a wii is in range
no you can not, you can only get ho-oh in Pokemon heart gold or soul silver, or you can get it in global trade.
When you start soul sliver press pokewalker and choose you Pokemon and connect it to you ds then Wala!
Lugia isn't available in Pokemon Emerald, it is available in other versions such as Soul Silver, Gold, Silver, Crystal, FireRed and LeafGreen.
You go somewhere with Internet...
No. You have to migrate six Pokemon from GBA games once you reach Fuchsia City.
yes. I've done it with both HG & SS.
These Pokemon are ONLY available through trade from leafgreen and firered without action replay. One exception is you can get one of them by beating RED (ash) in Mt. Silver on soul silver game.
There is no possible way without hacking or cheating. I heard they are bringing Mew back in Pokemon Heart Gold and Soul Silver.
