How do you breed Pokemon from Pokemon FireRed to Diamond?
To breed Pokemon from Poekmon Fire Red to Pokemon Diamond you
must put Pokemon Fire Red into the DS slot, turn the game on,
select Pokemon diamond, press start and then in stead of pressing
your file, scroll down until you see migrate from Pokemon Fire Red.
This will bring you to your Pokemon Fire Red PC box and you can
choose six Pokemon to migrate. After that you must go to Pal Park
on Route 221 and catch those migrated Pokemon there. Don't worry,
even if they're legendary, you catch them in one try. - BEWARE -
POKEMON MIGRATED TO DIAMOND CANNOT BE MIGRATED BACK
