How do you clone Pokemon in Pokemon FireRed?

you can with a ditto if you go to the day care

It is possible. You need to get the national pokedex first, and then trade that Pokemon you want to clone to emerald.(that emerald person must haz beat the elite 4 and national pokedex) he/she will clone . He/she must know how to clone the Pokemon in emerald.

you can also clone certain Pokemon in firered. but you have to have a ditto and the Pokemon you want to clone, then go to the day-care-center in island 4. if they have a egg, it is sertin that that is the Pokemon that you want to clone(NOTE)you must have already defeated the elite four and have a rainbow pass to go to island 4.

hi: from Matt
You can't clone Pokemon but you can make an egg by leaving the Pokemon that you want an egg from, and a Ditto with the lady on 4 Island. She makes them higher levels.

Once you have given them to her go back and forth between Vermilton City and 4 Island 10 Times and run around in between each one. When you finally go back the last time the man will say he has an egg. Take it, run around a shitload and after a while it will hatch.

Note.- Rare Pokemon can't have an egg. (Zapdos, Articuno, Moltres, Mewtwo etc..) - The Pokemon must be at least second generation. eg. Charmelion, Wartortle, not Charmander or Squirtle. - If the man outside the house says that the Pokemon don't get along well then they will make an egg.

Answer

go to the daycare and put dito and any Pokemon and just go to places In Pokemn FireRed, you can't clone. One thing you can do, is mate a male/female Pokemon with a Ditto on Four Island's Day Care. Just leave your two Pokemon there for a while, and the old man will be one step in front of the gate. Talk to him, but make sure you have room for one more Pokemon in you party. He'll give you an egg to hatch by running around for a long time. When it hatches, it will be your "cloned" Pokemon.
