master ball

I'm not quite sure what your talking about, but I would have to say that you would not have to catch it in a Master Ball.
Yes
you need to have two master balls.
go to the eight town and use master ball

Use an Ultra Ball, not a Master Ball
Of course, a Master Ball catches any Pokemon without fail, Legendary or not.
This is impossible without the use of cheat codes, unfortunately. Only the Master Ball can catch Pokemon without fail.
Yes, you can catch Dialga without a Master Ball. Dialga can be caught with any kind of Poké Ball but Dusk Balls and Ultra Balls would be the better options.
