Sorry but you can't get them on Pokemon Platinum. You have to migrate regi rock regi steel and regi ice from eiter ruby or sapphire, ( idk about emerald) i hope i helped ;)
Actually you're wrong you can NOT get the regis in Pokemon diamond, to get the regis you need Pokemon ruby/Sapphire/emerald you can get all three regis there(regi ice, regi steel, regi rock) althought if you migrate all of the regis onto Pokemon diamond you can get regi gigas(king regi) you will find him in the snowpoint temple after beating the elite four. Thanks hope i helped ^.^
by getting all three regi`s from Pokemon emerald, then you can go in and find the fourth regi. (Regigigas)
its not the best but it can help you find the regi's on emerald and ruby & saphire
a regi cannot have a egg in any Pokemon game because they are nongendered
you don't you must trade from Emerald, Sapphire or Ruby.
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 can only get regi ice in sapphire,ruby,and emerald.
If you Have a 11th movie regiggiggas you can find him in i rand island
first get the three regi's and go anywhere as long you can find a cave or dugeon
you cannot catch the 3 regi's in Pokemon platinum you have to catch them in Pokemon emerald then transfer them to Pokemon platinum. thnx
migrate it from ruby, sapphire, or emerald
