You can't.
There is no way to legitimately catch Ho-oh in Pokemon White. You must transfer it from HeartGold or SoulSilver.
You catch Ho-oh at the top of Celestial Tower after beating the Elite 4, ring the bell and it will fly out of the sky and onto the tower. Go catch it, it is at Lv.70. Good Luck!
You can't. You have to trade for one.
if you hack your game you can encounter a level 100 ho-oh
You can catch a Ho-Oh at Navel Rock in Pokemon FireRed.
No, you cannot catch Ho-Oh in Pokémon White 2, you can only get it in White 2 by either trading for it or by using the Poké Transfer Lab in order to transfer Ho-Oh from a previous game.
You'll need to trade for it, but you'll need the National Dex. You could also use the Action Replay.
Its not possible to catch Ho-oh in emerald to get one receive one from Pokemon colosseum.
