You have to migrate Pokemon from older games like Leaf green and Fire red. Then get them to your game. You will be able to enter the catching show. You can enter any Pokemon from the game you got Pokemon from.

You're just wierd i could always do it.
You enter it on the main menu.
All you have to do is talk to the lady in the front enter a contest with one of your poke'mon! :)
Some legendary Pokemon can't enter.
To enter the Pokemon League, you only need to obtain the eight Johto badges and then find the Pokemon League building.
You usually cant because you enter codes in Pokemon mystery dungeons its called Wondermail.
After you beat Clay, the Driftveil City Gym Leader, go left in Driftveil City. Just beofre you enter the gate, Bianca comes and battles you. When you win, you get HM02 Fly. Hope this helps.
