You have to download the Berry Fix patch, patch it to your game using a program such as Lunar IPS, and then it should be fixed.
From what i heard firered and leafgreen and emerald have this program and if you use a GBA link cable to hook up to sapphire or ruby you can fix your ruby and sapphire game, basically if sapphire or ruby is corrupted somehow this program fixes the games.
Check a berries tag in your Bag find a berry that has a red circle around the word Dry use this berry in the berry blender to make a blue pokeblock or liteblue. Try using a Ganlon berry.
