I'm not sure about this, but if you get an EZ-Flash 3-in-1 card and copy Fire Red into the NOR RAM, it might work. But I don't know if an emulator's SAV file would work with a GBA Loader.
You will need, however, to patch the DP ROM if you're using the EZ Flash 3-in-1. If not patched, DP will recognize the game in the slot-2 (thus being able to activate the "GBA insertion pokémons" event), but you won't be able to transfer pokémons, because DP will not find any save for the GBA game. Search the "poképatch" in GBATemp's download database.
Once you're done with the EZ Flash 3-in-1 ROM, replace the patched DP with the "clean" copy. The patched copy doesn't work with original Pokémon carts... well, assuming you have one.
