Can you trade pokemons in nintendo ds lite with pokemons in gameboy advance sp?

Answer 1

no

however, what you CAN do, is take the team from your gameboy advance cartridge, and upload them into palpark on your DS game.

what this does is virtually RIPS your 6 pokemon (per day) out of the GBA pack, and into the DS.

trades cannot be made from DS game *TO* GBA game

also, there are requirements in the DS games before any such things can be attempted
