I have a question and I'm not sure if anyone will be able to answer it. I've searched the web for a while unable to find any information on this particular cartridge. I have the Japanese version of annual crossing for my n64. It always somehow kept track of the time throughout all these years but today I plugged it in and found that the time and date was way off. I saved and later turned it back on. It had again, not kept track of time. So I am wondering. Does the n64 have a battery in it at all? Or does the cartridge. And if the cart does, how could it be dead if my game save is still there? Anyone know what I can do to get it to keep tie again? Thanks.
