Can anyone explain me something? I guess im too dumb.
I use to buy sfc games from ebay to play, and as soon i get them i always replace the battery first.
But in some games theres still a save data, and despite that i remove the battery and put the new one, that save is still there. How is that possible? Does the battery despite neing 25 years old still capable to charge the board enough to keep the memory for the minuted im doing the replacement? Thats amazing.
