Of course! You only need to have collected the Cobble Badge from Maylene in Veilstone City.
I think pokemon Black is better than the both of them. Still, I liked pokemon Platinum.
all the Pokemon on dimmond that can learn flash can still learn flash in the platinum game too
No, Bulbasaur is unobtainable in Platinum (you can still trade or receive it as a mystery gift).
no sorry
No
as long as the event is still going on, there is a way. it involves getting the same "event gift" in Pokemon diamond/pearl and trading to Pokemon platinum.
still the same Pokemon as d/p chimchar, piplup, and turtwig
there was an event for it which is now over. you can still get it by cheating :)
yes
In Pokemon Platinum you can't go to any other (that includes Kanto) region. I know it's upsetting, but you can still have fun by catching uncommon Pokemon!
It shows where you are.
No. The starters are still : piplup, chimchar and turtwig.
