Eliminate your batteries and avoid damage to your game! This 28 pin Dip NVRAM is plug and play and requires no soldering for most games. Replaces a 6264, 6064, 2064 or compatible pinout "8k x 8" SRAM Note about games with a clock / Midnight Madness etc:  This device will retain the RAM data when the machine is powered off, and will come back to the same values when the machine is powered back on. Games with real-time clocks will not advance while the machine is powered off.  This is not specific to this device, but NVRAM's in general.  You will still be able to utilize Midnight Madness modes, etc, but you will need to manually set the game clock to the desired time each time.
