Yes, once you get a new battery I bekive the screen will have a new egg. All you have to do is hit the A button and the B button and the same time. A screen will show and say down-load or reset. Chose download and you'll get your tama back!
Yeah you can. When you insert the new battery, an egg will appear. Press button "B" (the middle one) and choose Download and your old Tamagotchi will be there.
heyyyy but i got a better idea its really easy and you dont have to buy a new battery..okay here we go first:if it needs a new battery al you have to do it take it out and you can put it in the fridge or freezer for 3mins max and then take it out and put it bak in and it will work again!!!!and there you go a new battery ahahahahahaha
