When you beat the Elite Four u go to your dad and you get to go to the Battle Frontier now that's as far as I have been to but I think you probably get to the Kanto region aka Pallet town
I'm going to assume you mean "Pokemon Ruby" in your question. Anyway, to trade between Ruby and XD, you must beat Pokemon XD and defeat the champion in Ruby.
You have to fight her. xD No, but seriously, get a whole bunch of potions and fight with your strongest Pokemon. Just keep bashing on her Pokemon XD
They are about the same according to reveiws. no xd is there is more cipher to beat and the miror radar and catchin all of the shadows xd is the better choice
Snattle is not easy just have your Pokemon's level be higher than his to win, if i were you just beat his shadow Pokemon and wait till later to get them.
You have to beat the main storyline of the game and go to the basement of the Phenac City Pokemon Center.
You have to beat the game. not just beat the last part and see the credits. you have to beat the after story after you finish the game. i won't tell you what happens because i don't wanna spoil XD. but after you finish the game you can go and evolve easily at the luminous spring.
after you beat gorigan
At the orre colosseum.
yes you can. all you have to do is beat mount battle with the same party of Pokemon and after you beat the 100th trainer he gives you a choice of a chicorita a cyndaquil and a toditdile.
beat the game and get to the indigo or orange or whatever islands, where u find hoenn pokemon.
It will appear when u beat the elite 4
After you beat the Pokemon league then you beat the volcano after that you just train forever!!!!!!!!!!!!
