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
Majora's Mask doesn't use save batteries it saves to the cartridge directly like Super Mario 64. Nothing to replace unless you have a fake bootleg copy.
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.
