So, I started to play it, and then is said " Your file has been corrupted". So now I have to restart is
File has been corrupted or file has been erased? You're aware of the battery problem, right? You won't be able to ever save another game again unless you open up the cartridge and replace the battery.
That's actually not the case. I started a new game a while back and saved it and it worked great.
Oh I dunno, you may just have to start a new game, but try it again later anyway.
Oh, okay. I hope it works soon. I had Lugia and all the badges.
