Like Gameboy Colour games do?
no there’s a memory card that goes in the controller isnt there
no a nintendo 64 is a tv console not a handheld like a gameboy
no they save inside the cartridge
they save automatically to your nintendo and its plugged into the wall so it wouldnt need a battery
Yes I believe they do. Here’s one website.
However you can buy the N64s version of a memory card.
for certain games you need a rumble pack or a expansion pack.
idk good question
