I have a hand-me-down NES from a relative that sadly passed away, console works a treat but at some point within the past decade the cartridge batteries went flat. Finally have the gamebit driver to replace them but the gear is all packed away at the back of my storage cupboard…
Could always do the melted pen trick (outside; burning plastic is not good for you). Could risk melting the game cart plastic, though if you get the pen too hot.
Neat.
