Yes indeed it just lost its memory battery deleting all my data and is now unable to save any new data like my Silver does. And thus my old pal died along with my first official Mew. .R.I.P. Luckily my main team and strongest Pokémon where all moved to Pokémon Gold some 5 years ago. But I fear those Pokémon will be gone too when the battery fails within 5 years or so. So I decided to upload photo's of my strongest Pokémon including my shiny Ursaring and Raticate. Please keep in mind that I just went the lazy way and decided not to do all the stats of every Pokemon I own.
Editor's Note: I still need to check if my Gold but I'm afraid to... :\
