Did you know some Nintendo 64 games have batteries that need replacing occasionally?

While many Nintendo 64 Games require a memory card (Controller Pak) to save, some are not designed to save, and a lucky few save directly to the board itself, there are a few games that have a battery soldered onto the board for preserving the save file. Over time (15-20 years) the batteries can become depleated and need replacing.

The following is a list of Nintendo 64 games that feature a save battery:

1080 Snowboarding

Animal Crossing (JPN) for time keeping clock not save data

Dezaemon 3D (JPN)

F-Zero X

Harvest Moon 64

Ocarina of Time

Major League Baseball featuring Ken Griffey Jr.

Mario Golf

New Tetris

Ogre Battle 64: Person of Lordly Caliber

Pokémon Stadium

Pocket Monsters Stadium (JPN)

Resident Evil 2

Super Smash Bros.

WCW/NWO Revenge

WWF: Wrestlemania 2000

Funny enough the Controller Paks (memory card) also utilize a battery to save the save files! So even if you are saving your file externally on a Controller Pak that too will eventually need replacing
