You can't. You'll need to trade for them.
in my heart
No u cant but u can go to Kanto , also get hoenn starters and kanto starters
yes the 3 starters in kanto
By cheating or trading with other people.
Beat the 8 gyms and Red in mount silver. Go to Prof. Oak's lab and you will get the kanto starters (only one). Go to silph co. and talk to steven to get hoenn starters (only one)
no only johto and kanto but you can get the 3 hoenn starters
you migrate them from fire red or leaf green or trade them from soul silver or heart gold
yes you can
Use different pokemon.
well pretty much you can go to mount silver and battle red then you can get the kanto and hoenn starters
In heart gold talk to mr.pokemon on route 30 when you have gotten the kanto starters from prof. oak.
after u beat red the trainer go to oak in pallet and u can get one of the 3 kanto starters
