old cart repair


New Member
has anyone ever changed the batteris in a snes cart? i have a few that i fear need to be replaced but know nothing about it. what kind of battery does it take? is it the same battery for genesis carts? does it require soldering? i know nes carts require a certain kind of bit to remove the screws, is it the same for genesis cart? will save games be destroyed if they still exist. alot of questions but im just curious.

my manager used to change the batteries in his games. i imagine once the battery goes the save games are gone. im pretty sure theyre just standard watch batteries. open it up and take the battery to radio shark. pretty sure theyd have it there. iirc there may be a small amount of solder(?) on the battery.
