the old chateau in diamond is in the eterna forest. fly to eterna city then go left to eterna forest. but you have to cut the trees before you could go in to the old chateau.
near the end of eterna forest
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
the old chateu is only in Pokemon diamond pearl and platinum versions
Ghost,at least that what everybody says
just walk in the rooms and i guess that she will eventually come.
she is seriously a ghost so you can necer talk to her not even with cheat codes.
Go to the Old TV in the Old Chateu between 8pm and 4am. Rotom should come out of the TV and battle you.
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.
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
You cant catch Gengar in there, only Gastly and the Rotom in the tv.
