I found my old gold version cart the other day while cleaning. It was up on the top shelf a cabinet I was clearing because there was a ceiling leak above it, and the game was a little wet

I dried it out with rice and gave it a go. Surprisingly the game booted up just fine. However, when I went to start a new game because my old one was gone, the game froze after I tried to enter the time.

I know now that the internal battery has probably gone kaput. Does anyone know if replacing it will make the game work again? thanks

 

I haven't personally used this guide, but it looks legit:

Although instead of using tape, go to a store that deals specifically with batteries, if you can. They'll be more than happy to solder that battery in there for you, take out the old one too.

 

I just used tape to replace it and it works perfectly.

 

Yeah, that's understandable. but in this situation he probably won't be opening it back up again
