you can't.. make sure you have the three regi's and migrate them to Pokemon diamond/ pearl. You need National Dex. Now enter the Snowtemple in Snowpoint City. Regigas will be waiting if you bring the 3 Regi's.
Get three Pokemon from ruby,Sapire and emerald
You have to migrate ALL THE REGIS from Emeraled, Ruby ,or Saphire
migrate regirock, regice, registeel, and then you can access the regigas (migrate from emerald, ruby, or sapphire)
Regigigas is not avalible in Pokemon ruby, sapphire or emerald. Only regirock, registeel, regice are avalible
i am not sure but you should trade with someone who has ruby sapphire and emerald. One PKMN from each of those games you need to get Regigas i think
By redigas, do you mean Regigas? And no Regigas is a legendary. No Pokemon evolves into it.
DotBraille is Regi's language in Ruby, Sapphire and Emerald. By reading them in the walls and de-coding them, you can find Regi's (expect Regigas!).
You cant, he's a diamond/ pearl Pokemon and this game only uses Pokemon from games leaf-green/ fire-red , gold/silver and ruby/sapphire/emerald
you cant. use emerald or sapphire ,ruby for all the regis and there after go to snowpoint city to get regigas.
you can't
There is no Pokemon named regigas. so there is no code.
send it from ruby sapphire or emerald. their use is to unlock regigigas but you have to have a national dex, except if it's traded.
