You can get a iapapa berry from lostelle at berry forest also possibly from a Pokemon that has the ability pickup.
The only way to use berries in FireRed and LeafGreen is to berry crush with another FireRed, LeafGreen, or Emerald using GAMEBOYS (DS wont work) and 2 wireless adapters
No. But you can find them in the ground. Poke'mon Master
You need to link with a friend
Search around in the berry forest.
You can't get that berry in firered.
Surf east from Mauville and go east through the grass. You will reach an area with a house in it, that is the berry master's house, and his wife is inside it.
The berry master is just west of Hearthrome city. Unfortunately there is no berry master's wife in the game.
there is only one master ball that you get in firered
