What is the 4.5mm and 3.8mm Gamebit Screwdriver Needed to Disassemble Retro Video Game Cartridges?
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
A Collector or Player's Guide to the Original Sonic the Hedgehog Sega Genesis Variants
When it comes to retro gaming, few franchises evoke as much nostalgia as Sonic the Hedgehog. Released in 1991 for the Sega Genesis, Sonic the Hedgehog not only revolutionized platforming games but also became a cornerstone of Sega’s marketing efforts during the 16-bit console wars. Collectors of retro games often find themselves fascinated by the different retail variants of Sonic the Hedgehog cartridges and cases, including the original release, the second print run, and the iconic “Not For Resale” edition. This blog dives into the differences among these versions, examining their inserts, case designs, and how they were originally distributed.
The “Not For Resale” variant is significantly less expensive than the “Retail” version of the first Sonic game. Usually when we see a “Not For Resale” on a game cartridge we see $$$, but it is the complete opposite in the case of Sonic The Hedgehog for the Sega Genesis! Many people assume that the NFS version is more valuable and often you’ll see on local marketplaces that they jack the price up on these, but if you look hard enough, you can snatch up a Retail version for way less than on Ebay or Mercari. I have noticed that a lot of video game stores do not price these variants differently.

What Video Game Titles for the Sega Genesis (Alphabetical List) Take a CR2032 Save Battery? [NTSC-US/Canada]
Before we hop into the list of Sega Genesis 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

- 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
- We sell the (most of the time) required 4.5mm Gamebit tool! required to disassemble your cartridge! - Sega has a quite a few games that do not have the "standard" Sega bit.
