That's why I have both Gold and Silver. Sadly, Gold doesn't save for me anymore, so I have to start a file and get up to the point where I can trade. I leave the game on, restart silver, and once I can I trade all of my awesome pokemon back.

 

You could always change the battery so it saves....

This. There are a few guides on the internet for it.
