No because emerald version was made b4 Pokemon diamond and pearl so the software would not be compatible that's what I think Glad I could help! Ameri23
Put simply, you can't. You need two Game Boy Advance or GBA SP and a GBA link cable to trade on Pokemon Emerald. IF you need to get Pokemon from your Emerald version to your Diamond/Pearl/Platinum, you can do so after beating the Elite Four through use of the Pal Park.
