You should take Magnezone or Electivire
chinpokomon
There is no rental Pokemon in in Pokemon platinum
no but you must take with you a ds Pokemon pearl or diamond. then when you get platinum you will have to trade it from the other games.
you can't
take 50 flags in the underground
it's a game not a thing you can get (PS if you do get it you can take the code from the game when you get jirachi and you can put jirachi on Pokemon platinum) X24
In my opinion , you really should get Pokemon pearl , diamond or platinum , because are the best Pokemon games on nds near Pokemon heart gold and soul silver , but if you can decide , you should take Pokemon platinum because it has the sinnoh pokemons which are the best if you ask me and has a lot advantages in compharasion with Pokemon diamond/pearl , but you can also take Pokemon heart gold/soul silver due to its story , the ocasion in that you can have 2 starters , one from kanto , one from johto , and also the 2 Pokemon leagues and the oportunity of searching 2 lands in one game .
wat du u mean
take it to the rock up there by the Pokemon league
turn it off, take the GBA game out and make sure Pokemon platinum is in. Turn it on and select Pokemon platinum and - VOILA! it starts.
North of the Pokemon league (Take the seabreak path)
this is the same as Pokemon platinum, they are in the underground, they do take a while to find.
