Regigigas doesn't exist in sapphire.
You cannot get Regigas in Pokemon Sapphire as it is from the next generation of Pokemon
Regigigas is not avalible in Pokemon ruby, sapphire or emerald. Only regirock, registeel, regice are avalible
migrate regirock, regice, registeel, and then you can access the regigas (migrate from emerald, ruby, or sapphire)
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
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.
There is no Pokemon named regigas. so there is no code.
i think you can trade for a regigas but i dont think you can catch 1. but...if you have pokemon sapphire version then you should already know HOW to so try the same way as you did (IF YOU HAVE THE GAME AND HAVE PLAYED IT)do the same thing
