Personally, I’ve yet to come across an NES cartridge in my collection that has a dead battery. I don’t know anyone that is in that situation either. That doesn’t mean that there aren’t millions that have this problem! If you’re one of those unlucky people, you might want to check out this guide. It’s a step-by-step feature on how to fix up your NES cart on your own. I’d probably end up breaking the cart, but I know some of you are much more handy with this kind of stuff!

Bam. Media blackout on that until you tell us otherwise.
