there is no way, all you have to do is the slow boring way. sorry
No unless you are realy good at the game!:)
There isn't a way to make it hatch fast, but the best way is to put the egg first in your party. It doesn't walk with you, the Pokemon who you put 2nd in the party will but it's a pretty fast way to hatch an egg though.
Action Replay, Pal Park (National pokemon),or Hard work and time.
you have to beat the pokemon leage
no there are no cheats to this game but you can get mods
you need all of the gym bades
The easiest way to catch all the Pokemon is to start with the Pokemon with the lower levels and continue until you reach the highest leveled ones(which is rayquaza, kyogre, groudon and maybe latios OR latias
In Pokemon Gold/Silver/Crystal/Heart Gold/ Soul Silver you can have it as a starter but otherwise the only way to get it is from trading.
If your legendary Pokemon run away in Shiny Gold, there is no way of retrieving them again.
Use a fast ball or get a Pokemon with the move Mean Look so Raikou can't escape from battle. Have a magical day!
no way hosay
