I'm trying to help out a friend by fixing her copy of Shining Force. I'm pretty sure the battery inside the cartridge is dead, as the saves keep on getting erased.
So, I opened the thing up to poke around and I think the battery is attached to the little latch.
I think this has been asked before, but I searched for it and could not find anything on it. So, is it possible to replace this battery without killing the game?
