You can't transfer diamond and pearl Pokemon to emerald, but you can trade Pokemon emerald to diamond and pearl.
To do this, first see all 150 Pokemon, then go to professer Rowan, get national dex. Professer Oak will come along too, and he'll tell you about pal park, the thing which you need to trade old Pokemon from old games to diamond or pearl
i believe that you can trade sraight away eg the first Pokemon centre in viridian city(accordin to my friend who has the game where as i only have ruby n sapphire), but if you want to trade to ruby/sapphire you need you get quite away ito the game after you beat the blaine(senventh gym leader) yo get to the sevii islands and aftre you get the national dex which consists of catchin 60 Pokemon n then you have ta go see prof oak n he will give it to u. n after all that you hav to find 2 gems a ruby n a sapphire n wen you get them u can trade to ruby n sapphire. if you don't no where to find them look somewheer else think i put a bit 2 much down lol
well hope this helps
