So i bought "one of those carts" from Ebay and it does not want to save. In the game when i try to save, it tries multiple times and says the battery has run dry. I opened it up and i did not see a battery to replace so i figured i will install one. I got a CR1616 and i soldered it correctly. Tried to save and yet again it does not want to save. Is there anything else i have to do to the PCB? Bridge something? Cut some line? Maybe someone can help me out here.

There is this guy on youtube that explains how to do it but his PCB is different,

Im guessing it cannot access the battery?

Thanks

Solution
Honestly, given the age and current state of the PCB, I don't see what could be done on it.

If you used the right battery and did the soldering done right, it could be other issue than just the battery.
