You can if you want to.
you can use cheats or have a regigigas from the 11th movie
Just just hit the menu button, then it should say cheat and press that. After that, input the cheat by having a cheat, which you can look up , and after that you should be able to use the cheat if its the right one.
you may not be able to use your catalogue if you use that cheat! :(
their are no regies in pearl or diamond besides regigigs but u need the three regies to get him in the snowpoint temple.
Yes you can.
No u cannot use cheat codes for ''Mercenaries 2 world in flames'' due to it needing internet connection to be able to activate the cheat code(s).
no
you must trade them
regigigas
there the home of the regies
Yes a Pokemon modifier, but you have to have action replay to be able to use it.
IN D/P and platinum after you get the regies you need to have the three regis in your party and off you go to snowpoint temple to catch regigigas
