Before we hop into the list of N64 Video Game Titles that use a battery for the save function we wanted to note that replacing a dead or dry battery does require soldering and certain tools listed below. 

Requirements for soldering: (Most of this is easily found on Ebay or Amazon)

  • Soldering Iron - Recommend a full soldering station 
  • Here is a link for an X-Tronic under $70 on Amazon - X-Tronic 3020 Soldering Station 
  • If you're not an Amazon fan, then perusing Ebay is definitely your best bet!
  • A CR2032 battery with solder tabs. You can check out our short tutorial on basic soldering here.
  • Many of the new save batteries are duds, so if you have a multimeter they are easy to test. Just like a car battery - positive to engine to steering wheel... wait? Also, the save battery may not be the issue you are having with your game (Usually is) but if your old battery is reading at 3 volts, then you may have to explore other avenues to get your game to save properly.
  • Flux Paste - Recommend MG Chemicals Brand
  • Desoldering Copper Braid - to soak up solder (Also recommend MG Chemicals brand for this one too!
  • We sell the (most of the time) required 4.5mm Gamebit tool! required to disassemble your cartridge! - You will also need a phillips screwdriver for two interior screws. In case you want to start soldering and disassembling game cartridges and consoles then here's some recommendations. I personally love the IFIXIT precision tool kit so here's a link to the

When it comes to retro gaming, whether you're a collector, someone who loves to repair and restore old gaming cartridges or you simply just want to see what the inside of a retro video game cartridge looks like, then understanding the tools required to disassemble these games is essential. One of the most crucial tools in your gaming kit when dealing with classic game carts such as, but not limited to, the Nintendo NES, SNES, and the Sega Genesis is the Gamebit screwdriver. These specialized tools are designed to handle the unique screws used in these systems, particularly the 3.8mm and 4.5mm variants. These games aren’t getting any younger and if you want to really get in and clean those dirty carts or just study a board, then let’s educate ourselves on the gaming bit required to disassemble those bad boys!

Dude… What Are Gamebit Screws?

Gamebit screws are distinctive, five-pointed screws used in many retro gaming cartridges. Their unique shape is designed to prevent tampering and unauthorized repairs, making them a pain for anyone trying to disassemble these devices without the right tools. Remember, Amazon didn’t have cheap and super-fast shipping back when this preventative measure was first implemented. Although, back in the 80s and 90s, people still got their hands on these bits and would sometimes switch out the boards in game cartridges from the video rental store. Remember those? To open up these game cartridges, you need a 3.8mm or 4.5mm Gamebit screwdriver... most of the time. We’ll dive deeper. However, these sizes are the most common for accessing the internal cartridge components safely and effectively

Soldering can be scary for a lot of people at first. My first SNES save battery took me at least 50 minutes! Vegas Stakes! Now, it usually takes me 5 minutes. I wasn’t using the right equipment and obviously people tend to get better with practice. These are some suggestions for setting yourself up to solder!

  • Buy a nice solder station. (Usually, will come with a roll of solder roll)
  • Use the appropriate solder. (some elements work better with electronics than others) We recommend a 60 percent amount of tin and 40 percent lead.
  • Use copper desoldering wick/braid with flux. (We recommend 2.4mm in width)
  • Have flux handy! (No-clean flux preferred)
  • Isopropyl alcohol. (preferred percentage minimum of 90%)
  • Q-tips.

Let’s start with something simple:

  • Power on your soldering station to approximately 600 to 650 Farenheit (You can use lower temperatures).
  • Place your no clean flux on the old solder you want to remove.
  • Cut a piece of copper wick braid to use for desoldering
  • Copper conducts electricity, so be prepared for the braid to become hot
  • Once your soldering iron is at the correct temperature place it over the old solder and hold it into place until you see the old solder s
