The Game Master...
Well obviously not. every single Pokemon in the Pokemon emerald pokedex is not registerd in Pokemon silver. There are some in the national dex but not in the original dex. No New games can trade or battle with old games. unless they have made say Pokemon acrylic and then make Pokemon cyan with the same region and near enough the same Pokemon then yeah.
PS: There is no such thing and probably never will be as Pokemon acrylic and cyan

No, only from emerald to silver, but i dont see why you have to, you have the region already there.
Red, Blue, Yellow, Gold, Silver, and Crystal can trade between themselves. Ruby, Sapphire, Emerald, Firered, and Leafgreen can trade between themselves. Games from list 1 cannot connect with list 2.
No but you can migrate emerald Pokemon to heartgold
you have to trade it from Pokemon red to silver (u need the time machine) then trade it from silver to any version and so on :)
Leafgreen can only trade between firered, ruby, sapphire, emerald, Pokemon colosseum, Pokemon xd gale of darkness, and migrate with diamond, pearl, platinum, heartgold and soulsilver it cannot trade with the original silver.
Sorry... Just... get Gold or Silver and trade.
You have to trade Kyogre from Pokemon Sapphire, and you must trade Rayquaza from Pokemon Emerald.
You can't
Transfer it from emerald OR trade it from soul silver or heart gold
no you can not...but you can trade heart gold and soul silver Pokemon to diamond pearl and platinum
There is no emerald to trade between firered and emerald you need wireless adapters.
