Battery Holder no NVRAM Upgrade (Recommended)
$ 1.91
- We don’t sell or recommend NVRAM conversions. They add unnecessary complexity and introduce another potential failure point into a system that was designed to be simple. Instead, we strongly recommend installing a remote button-cell battery holder with a standard CR2032 lithium battery. Why? Because it just works. For about $3 every couple of years, you get reliable memory backup with virtually zero risk of leakage or board damage. In the worst-case scenario, you lose your high scores… not your MPU. It’s the simplest, safest, and most cost-effective solution. Keep the game original, eliminate corrosion risk, and avoid over-engineering a problem that already has a clean fix. ***Battery Not Included – Brand Name batteries are strongly recommended & will last for years
