Ik ben persoonlijk gek op retro gaming en zonder enige twijfel is de SNES de leukste 16-Bit console ooit gemaakt. Deze console werkt tot in tegenstelling van Xbox 360's en PlayStation 3's na twintig jaar nog altijd perfect en zonder enige problemen. Helaas geld dit niet voor sommige games waar een batterij in zat om je save games mee op te slaan, want deze zijn na al die jaren leeg en dat is natuurlijk niet leuk. Maar als je een beetje handig bent kan je deze zelf vervangen met deze stap voor stap handleiding.

It turns out that all SNES games that save use RAM, or something similar, to do so, and thus have watch batteries inside the cartridge to power the memory circuit when the cartridge isn't in the console. Those batteries have an expected 10 year lifespan, although some certainly last longer. But in our case, it was time for some cartridge surgery, something that every SNES gamer is going to have to do at some point. Thankfully, it's pretty easy to do.
How to change an SNES battery

First, you'll need to go shopping. The main things you'll need, as shown above, are:

A 3.88mm security bit to remove the cartridge screws
A CR2032 battery
Electrical tape
A sharp razor (we used a regular razor, but an X-Acto knife might be even better)
A beverage to help steady your hand, as we are talking about reanimating pieces of history here.
For more permanent installs, you can also solder on a new battery, even using a pre-connected terminals like this one.

Before we get going, let me just drop an important disclaimer: You will lose any games you have saved when you do this. They'll be gone forever, but if you do it right, you'll have another decade or two to get those saves back. As such, I suggest doing this preemptively when you pick up a new cart, or waiting until one you have is totally dead. There's no good way to try to replace a battery without cutting power to the cart, and I'm not going to be the one to try. Also, we're talking about fairly delicate, old electronics, so I'd practice on something cheap before you start. If you break something, don't blame me, okay?
