Pokemon Crystal/Silver/Gold

My silver and my Crystal will not save, anyone know what I can do to fix it?

The battery is most likely dead, buy a new game.
I don't think Nintendo still has Game Boy Color games covered under warranty anymore.

Wikipedia says that the the memory chip will stop working after a couple of years. The only left to do is either replace it or buy a new Silver and Crystal.

go on ebay and buy new ones

i already bought new ones guys but they all dont work
but now i have the VBA on the computer and i can play shiny gold all i want

You're probably SOL once the battery dies in those games. The only way to fix it is to send it to Nintendo, and I doubt they still have batteries for games that old.
