I bought Pokemon Gold from a yardsale awhile back and I just played it yesterday and it said, 'New game'. I didn't think anything of it and continue to play for 7 hours. This morning I turned on my gameboy to see 'New game'. No saved game. I know for a fact I saved multiple times while playing. Is there anyway to fix this? I read somewhere that the internal battery died but i'm really not sure what to do. If there is a way to fix it could you please tell me the steps to fix it? Or if Nintendo could fix it but its an old game..would they do that?
