you can't
Yes, it's possible. Only if you have a DS. With a DSi, it's not possible. The DSi does not have the GBA slot.
Pokemon Emerald was only released as a GBA cartridge, the DSi XL has no GBA slot so you can't play it.
Pokemon Sapphire is a GBA game - since a DSi does not have the GBA slot unlike the regular DS or the lite, it cannot play Pokemon Sapphire.
You can't. It has no GBA slot.
You can trade in your gba, but you probably wont have enough money to buy a dsi.You won't even have enough for a ds.
Well if the DSI has a GBA slot then yes.
You can migrate GBA Pokemon to a DS Pokemon game but you can't trade using the GBA game trying to trade with another GBA game.
Yes, using Pal Park, you can migrate Pokemon from GBA games to Diamond, Pearl and Platinum, using slot-2 on a DS. However you cannot do it with a GBA itself, or a DSi. Only an original DS or a lite can do it.
you need a ds or a ds lite (not a dsi , dsixl or a 3ds) put emerald in tehe gba slot then turn on Pokemon soulsilver . in the menu, you will see a new option .touch it, then you will automattically be able to trade with your Pokemon emerald!
even if you could get into pal park without a gba Pokemon game it would be pointless because the only Pokemon found in there are the ones migrated from a gba Pokemon game that you have in your ds/ds lite/dsi
no.
Just like in Diamond and Pearl, you have to have an old DS or any DS because the DSi. You cant trade your Pokemon between them but if you got the gba game in the ds with platinum, you cansend your Pokemon to the DS game. You cannot however get them back on the gba games.
