It's easy all you have to do is trade with leaf green
You can't without action replay,gameshark,etc.
its impossible without gameshark or action replay.
Trade from Pokemon leafgreen or firered
You can't.
You cannot unless you use an Action Replay or Pokemon Leaf Green.
On an action replay, its program or ect.
you have to use action replay or to get alot of Pokemon migrate from a firered and use action replay on firered to get all Pokemon except the one from diamond
You can NOT battle Professor Oak in Pokemon FireRed Version, even with an Action Replay
you don't
It is impossible unless u have action replay or another hack system
you could download the ROM from romsite.net and get the VBA emulator from any emulator site then go to the game shark codes site and find firered or firered/leafgreen and use the cheats to do that. either than that, its impossible
there is no Pokemon x... if there is its a glitch or an action replay code
