near the end of eterna forest
the old chateu is only in Pokemon diamond pearl and platinum versions
No, the only way to get Gengar is to trade a Haunter.
i dont think you can i suggest you get gastly and evolve it
just walk in the rooms and i guess that she will eventually come.
Ghost,at least that what everybody says
there r 2 good places to get ghost Pokemon on Pokemon diamond: the old chateu in eterna forest and the lost tower by solaceon town
she is seriously a ghost so you can necer talk to her not even with cheat codes.
Have a gba Pokemon game inserted and go to the old chateu, then go to the room with the T.V. in it and press the A button.
Go up to the screen and tap A. Remember, it has to be after 8 o'clock for Rotom to show up.
In Eterna Forest.
It Is In Eterna Forest At The End
You cant catch Gengar in there, only Gastly and the Rotom in the tv.
