using the Pokemon cloning technique save before you get the first and second Pokemon but save after you get the third Pokemon. you have to vs your rival, take back the egg and have at least two Pokemon. you will be able to control all three Pokemon cus technically they were all owned originally by you. you must not save after you get the first and second Pokemon. that's it.
Enjoy
its simply not possible
There are two possible ways: Choose Treeko as a starter Pokemon Or By trading
by trading or cheating
trading, and cheats (like gameshark)
Have it as a starter Pokemon and then trade it to a game.
Umm....Gameshark Cheats,and trading. If its on Ruby and Sapphire,its on the Pokemon colloseum and Pokemon channel
i like gronola bars
All if you have a gameshark
GameShark is the only other way.
You cannot get these pokemon without trading. But you can cheat by using gameshark codes.
Jirachi is a distrubtion pokemon that is not obtainable anymore unless by trading or cheating (gameshark)
no you can't you have to either trade or gameshark cheats :P
