Pokémon Fire Red/Leaf Green came bundled with a wireless adapter, which allows you access to the Union Room. This is a place where you can talk, trade and battle wirelessly with other people in the same room as you. You also have access to the Berry Crusher.
Berry Crushing is Fire Red/Leaf Green’s version of Ruby/Sapphire’s Berry mixing. You must be in the Union Room to use it.
You also need the Key Item, ‘Powder Jar’. This is located in the western house north of the Pokémon Centre in Cerulean City.
Berry Crushing involves all players placing a berry into the device and tapping A rhythmically. The better you do, the more juice points you get. These can be exchanged for items at the house north east of the Pokémon Centre in Cerulean City.
