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

The motherboard design of the 1-CHIP SNES enables it to output better graphics than earlier revisions of this Nintendo system. The 1-CHIP is highly sought after by collectors because it offers some of the best gameplay visuals you can get on a Super Nintendo. It is also somewhat rare to find, which makes treasure hunting for it even more thrilling!

Prior to the year 1995 or so, Nintendo designed their Super Nintendo console motherboards so that they used 3 chips for graphics and central processing. These three chips are called the CPU, PPU1, and PPU2. When Nintendo revised the SNES motherboard around 1995, all 3 of these chips were combined into one single chip called the S-CPUN. This hardware change is what gave this model of the SNES more graphics processing power.

How do I know if my SNES is a 1-CHIP version?

1. Look at the serial number.

The serial number barcode is printed on a sticker located on the bottom of the console beneath a barcode.

One obvious indicator that you may have a SNES with a 1-CHIP motherboard design is if the console's serial number begins with "UN3". A 1-CHIP SNES serial number will always start with a UN3. However,
