You have to beat all the gym leaders.
Or you can use the Action Replay code to get all badges. This can mess up parts of the story so I recommend against it, unless you've beaten the main game before...
Same as every Pokemon game. Defeat the Gym Leaders to get the Badges.
On Mt. Silver but first you need all 16 badges and victory on the Pokemon League
yes
no such thing
he tells you that you need to get all of the badges from Kanto then he will let you into Mt. Silver
Once You Have All 16 Badges, You Can Attempt To Catch All 250 Pokemon, Battle Red Who Is Found At Mt. Silver And Try To Find Somebody Else You Know Who Has The Game And Battle Them. The End.
You'll need all 16 Gym Badges then you can go to Mt. Silver.
16 badges
you could always go to mt. silver if you get all 16 badges there is 40+ pokemon.....
after getting all 16 badges go talk to prof. Oak then go to mt. Silver
The top of Mt. Silver. You need all 16 gym badges and have rock climb (courtessy of prof. oak).
There are 8 badges in each and every Pokemon region except for the Gold and Heart Gold versions/Silver and Soul Silver. (there are 16) (if that wasnt known..)
