The closest thing to an answer I could find was from an SNES FAQ:

H. The battery inside my game is dead, and I can't save my game data anymore. Can I replace the battery myself? What kind of battery do SNES games use?
The batteries themselves are standard CR2032 lithium batteries, but with metal mounting "clips" spot-welded to the battery. You can probably buy a replacement at many electronics stores. Alternatively, you could fit a suitable battery holder, to allow you to use a normal CR2032 battery, and allow easier replacement in the future.
Thanks to Mark for the info.
Alternatively, you could contact a Nintendo Service Center, and ask if they can install a new battery. You can expect to pay quite a bit for the service, however. |
So, the same *might* hold true for N64 games, but the battery type could be different. Keep in mind, the saves are already lost so changing the battery won't bring them back.
What game is it? I've never had a problem with any of my N64 games, and I haven't even experienced the problem on any of my original NES games yet.
