machoke - machamp, haunter - gengar and Kadabra - alakazam
Using the dual-slot feature with firered or leafgreen will make it possible to find gengar in the second room from the right on 2F
Wild Gengar can appear in the Old Chateau if you have Ruby, Sapphire, Emerald, FireRed, or LeafGreen in the GBA slot. In this case, it has a 4% chance of appearing.
To get a Gengar you must first catch a Haunter. To evolve the Haunter you have to trade it to another gaming system.
Blastoise Raichu Butterfree Fearow Nidoking Rhydon (Gengar but put in Nidoking instead incase you cant trade) =]
You mean how you get Gengar then train a gastly to level 25 it will evolve to Haunter then trade to a friend who has firered or leafgreen your haunter and then take it back when you receive it it will be a gengar.

Put in a Pokemon GBA cartridge in the GBA slot (Ruby/Sapphire/Emerald/FireRed/LeafGreen) and then go to the Haunted Mansion in Eterna Forest, inside you will have a very rare chance of finding a Gengar.
