If you want to transfer them into your gen 4 game, then you can trade the pokemon into the legit cart, then use Pal Park with the real copy.
I did this to play Emerald recently, so I highly recommend it over shelling out all that cash for a real copy. Getting a flashcart also makes it where you can play any GBA rom you want and you can easily mod your save if you want to avoid long grinding sessions by giving yourself a Lucky Egg, just raising your team's levels, etc.
Bootleg carts aren't worth it since they can barely retain their saves and can't be used for Pal Park.
