I never realized how much we take flash memory for granted. A little over 20 years ago the go to choice to save your game using a Nintendo Game boy color was a lithium battery. This was an excellent cost effective choice at the time since the batteries had a 7 to 10 year life span. Nintendo never counted on how resilient their games would be, or even how nostalgic their customers are.
Fast forward to present day and the lithium batteries have all gone dead making it impossible to save your game for later use. Luckily with a couple dabs from the soldering iron and a $2.00 battery your cartridge can be back up and saving games in no time!
TOOLS YOU CAN USE
You will need a good soldering station. Soldering stations come in all shapes and sizes and price points
Something like the one to the left sells for about $50 on Amazon. If you’re like me I would spend a little more for variable heat control and some extra tips.
