How do I know that I need the Berry Update?

Applies to: Game Boy Advance

In certain editions of Pokémon Ruby & Sapphire, berries no longer grow on certain trees after you play the game for a year. This does not affect any of the main activities like catching Pokémon and Pokémon fights. If you want the berries to still grow after one year, please read the following information on how to update your game.
