yes, only if you have a ds. put sapphire in the gba slot. then in the menu, tap "migrate from Pokemon sapphire". tap the Pokemon you want to migrate and after the migration, the Pokemon will be at the pal park to catch. the pal park is at fuchsia city in kanto.
YES
You can 'MIGRATE' Pokemon but, I don't think that you can trade them because the sapphire version is for the GBA and Pokemon Soul Silver is for the NDS.
you have to trade him from soul silver or migrate him from Sapphire ruby or emerald.
by either trading with Pokemon heart gold or Pokemon soul silver, or you can migrate from ruby, emerald, and/ or Sapphire
You have to trade Kyogre from Pokemon Sapphire, and you must trade Rayquaza from Pokemon Emerald.
you cant its only in soul silver and heart gold
Route 114 is only in Sapphire/Ruby/Emerald.
no sadly it can only be used in ruby, sapphire and emerald
you cant beat steven in pokemon soul silver only in emerald,ruby and sapphire
You have to use the Pal Park option which is only available after obtaining the National Pokedex. Even then it isn't trading, you are transferring Pokemon from Sapphire to SoulSilver.
trade them from Ruby, Emerald, or Sapphire, or... trade them from a friend, or... get them from the GTS.
Ruby, sapphire, emrald, and crystal(crystal is the old version of soul silver);~]
