Pretty much what it says in the topic. Back in late '08 my 3-in-1 stopped saving, so I let it lie for a while then got a replacement battery. Stuck the new battery in, and now it still doesn't seem to save properly, and has some trouble loading (though that might just be from me renaming things to keep my saves from being overwritten with nothing.) It often saves a save file with gibberish for an extension (eg. %寣寣) that either seems like the save only misnamed or is sometimes just empty. Any ideas?
