Yes! Simply replace the battery and press Reset. Download and Reset should appear on the screen. Select Download and press B. Your Tama will return to the last major event in it's life.
thanx. it came back right when you posted that. but what i dont get is, nothing major happened today! It just started from 10:49 am, the time i played with it when it went
I think they did upgrade the feature because when my U.S. ones battery died she had her baby and was going to leave that night. I just replaced the battery and rather than going back to the major event of when the baby was just born she left at 12:00am like she was supposed to. So I think it recovers up to the point the battery died which is even better.
All you have to do is buy a new battery and when you do you can just hit the button that sends it to your old Tama, the stuff might be messed up though. (Time, date etc.) Here's a trick till u get a new battery, hit the reset button it will still work but onky for a little bit.
