Were you already ready to catch the time/space  of that version, but they Ditched you.
well here is a cool trick i know of. if you killed or defeated them the First time, go
back to mount coronet, head towards the Spear Pillar and where the first Dialga/Palkia was
there's another one O-O, odd huh

but it's true, use a good catching strategy to nail

that darn legendary of yours into that darn Poke Ball for the final time. and now all your
worries are gone from the face of the earth for not catching the darn legendary Pokemon.

Go to Jubilife City, go to the lottery corner. In the jubilife tv station. Talk to lady
behiend the desk 1f. When the dots come up go in a curcle on your control pad. you should
get a backdrop. It works about 75 percent of the time.

When your catching a pokemon throw the pokeball the keep pressing B and you have a 60%
chance!

when you are trying to chatch dialga or palkia do not use your master ball on it u have a
very good chance of getting them with a ultra ball or if it is palkia use a net ball.

all of the people that post a cheat here your noob your using cheat to be a master.

Do not listen to Chimchar's - get every pokemon in sinnoh cheat!!!!!!!!!

this is so simple 2 get a happiny egg frst u fly to hearthome city you will be in front of
the pokemon center you run down when you see the poffin house take a right you will see a
guy in a red suit go down the road hes on then you will see a grass path take the path
talk to the man on the path you have to have space in your party in order to do this talk
to him and say yes to his question you will get an egg. now, this is the tricky part. you

  if you have AR  add a cheat called get any pokemon. this is the code: 94000130 fdff0000 
b21c4d28 00000000 b0000004 00000000 a9400013 
 0feff000 00000089 001ed000 1d000000 00000000 00da0000 00000008 92dc0000 00000246 20c00000
0bd70000 00000000 00dc0000 00000000 06d20000 00000000 00000062 ad200000. after you do that
in your game press L+R. there should be 493 master balls in items pocket.EXAMPLE: dont
take away any masterballs. press L go in the wild and theres ARCEUS. whatever number of
master balls you have if it matches a pokemon number on national thats the pokemon youll
get.

    plz rate!!!!!!
    

You need an action replay DS for this. I dont know what the code is but when you do have
the code push l+r on the menu. you will get 493 master balls. If you toss a certain amount
you push L and go in the grass. wala! For example 493-0=493 Arceus or 493-10=483 dialga

Go to canavle city get on the boat that takes you to iorn island...once you arrive at
ioron island go to the cave search for a girl named rily,she looks like sir aoron from
lucario and the mystery of mew and go battle trainers and wild pokemon...then once you see
2 dudes with blue hair go get them because they are team galactic

then rily will give you a  a lucario egg you have to hatch the egg and get the pokemon
that comes out of the egg to evolve

first you have to talk to the guy in solaceon town and talk to the reporter in the house
near the pokemon center. HE will ask you for a pokémon.

 Catch that pokémon, or if you have it go to a pc and withdraw it from the computer. Go
again to the reporter, save before talking to him and then talk to him. You will probably
get dive balls, or quick balls (he gives 3 balls of any kind). Turn off the power if you
didn´t get the masterballs and talk to him again till you get the masterball!! Remember
you can only talk to the guy once per day

First go to the underground then touch the bottom screen there it will be stars in the map
go to one of those stars there you should find one fossil.Or you can migrate pokemons from
other games

get all of the shards and plates and when you do go to Pastoria city. walk into the
pokemart and talk to the croagunk statue. it will say:"CROAGUNK SEEPED OUT THE AZURE
FLUTE!"

u can only get them on a monday go to the statue at eterna and look behind it if it is a
monday you will pike up a masterball.

P.S. if it is your 1st time looking behind the statue you will only find a Draco plate

first you need to get regirock, regice, and registeel.then you need to beat the elite
four. finaly you need to snowpoint city there should be a entrance near the top of the
city were a women will tell you that you can't go in, but then the gym leader of that city
comes. make sure you have all the regi pokemon. go to the very bottom of the cave. there
you will see a statue. go to it and push A. it will react to the regi pokemon and battle
you. bring at least 30 ultra balls or a master ball.

when you enter the pokemon mansion on pokemon leaf green/fire red go up then the third
rock on your left (west) press a in fornt of it and you will recieve a moon stone!!! trust
me it works 100 percent of the time if not then try all the rocks ok!
