How to fix Nintendo 64 & SNES games that will no longer SAVE (battery change) 

Is it possible to use a memory pak(controller pak) to save, if the battery on the cardridge has run out?

Maybe a stupid question , why doesent it just save to the little carthridge thing in the controller if the battery runs out?

Most games didn't require any battery at all for saving. Both SM64 and Majora's Mask didn't use a battery. Saved to a chip on the cartridge. Dunno why Ocarina needed a battery...

Hey What all do you need I saw on the video but I was just trying to be precise so I can get the parts because I’m having the same issue with one of my games for legend of Zelda majora’s mask

If you do not put the black piece of plastic back in it save files will not load trust me my megaman 64 i left it off when i cleaned it.

Damn i have one question can anyone tell me what are the best setting for the sodering iron ?

Where do i get the stuff to fix it?

Can u break it by doing this

My super mario 64 cartridge and vrally 99 doesn't have battery.... On vRally 99 I had issues an error saying that the battery is not working so I opened it today and I found no battery inside! what is going on with this carttrige I don't know. I cleaned it a bit and I hope that I won't have this issue again.
