PLEASE HELP!!!

Unfortunatelly there's no way to recover overwritten saved state, I also had this same problem some time ago. A confirmation message would be a nice thing to devs to implement on emulator, also the emulator should automaticly make a backup of last saved state for security.

But I recommend you to always use the save game even you're using the save state. Native save never fails, but save states is very unstable and uncompatible with newer emulator versions.
