My 1999 Pokemon Yellow savegame is gone... :(

Sad days... after reading this: http://xbigygames.com/save-your-pokemon-game-files-before-its-too-late/ which explains that around now the battery will die in your original Pokemon cartridges after all these year, I checked my Pokemon Yellow Gameboy cartridge and it was too late... -_-"

Are your Pokemon savegames still save?
