i have never heard of that before

i have it too

hey can you get jirachi and deoxys

I have the same problem too. From my Google expedition, I can only gather that internal
batteries must be fixed by Nintendo (contact their Customer Service) and will erase your
saved game -sorry :(- There's a rumor that linking LeafGreen or FireRed (newest
generation) will fix it, but it's only to an extent. Without internal battery, you will
not be able to grow or get berries or go into Shoal Cave at different tides. Instead, it
will stay at one tide (I had the bad luck of having it at high tide) AND the game clock
will remain the same (clock in ur house, manually changing the time won't work but the
game still counts how long u play it).
-Hope u fix it!
