I'd recommend a master ball .I think dawn should've given you one. If you already used it then read the following:
#1 The ball can catch any Pokemon at any lvl at any hp even dialga lvl 100 (it isn't really its 47)
#2 you only get 3 in the whole game and you shuldnt have used it
Hope i helped :D
In the game Pokemon Crater, Dialga can be obtained by defeating all of the Gym Leaders as well as the three separate sets of Elite 4. Once that is done, a Dialga will eventually appear in the cave maps.
If you defeat, flee, or capture Dialga before you defeat the Pokemon League, it will appear after you beat the Pokemon League. If you defeat it a second time or if you defeated it after the Pokemon League, it will keep regenerating after you defeat the Pokemon League. If you don't defeat the Pokemon League then it won't reappear. REMEMBER: YOU MUST DEFEAT THE POKEMON LEAGUE FIRST.
When you catch up to Cryus (the leader of team Galactic) at the Spear pillar. After that make sure dialga's life is at the yellow or red zone the use a dusk or ultra ball , if that doesn't work use your master ball, while you are catching dialga in the master, ultra or dusk ball press a , b , b, b than after while the master , dusk or ultra ball shakes left press y.

If you beat Dialga and Dialga faints, you can no longer catch it.
It depends on which game. you can catch dialga on pearl with a code
You can catch it by first turning Dialga's HP into the red. Then use Ultra Balls or Dusk Balls to catch Dialga. It will take time, and you need to use a few balls to catch Dialga.
