Step 1: Materials and Tools Needed

NES Game Cartridge
(Preferably a very common game)

Belkin Wireless G Router
Model: F5D7230-4

Gamebit (3.8mm) or Flathead Screwdriver
Dependent on cartridge type 

Soldering Iron
Low-heat soldering iron is recommended


Thin Wire

Razor Blade

Desoldering Iron (Optional)

Desoldering Braid (Optional)

Pliers (Optional)

Step 2: Disassembling the Game Cartridge

First, identify the type of NES cartridge you have and acquire the appropriate screwdriver. One variation uses five flathead screws to hold the cartridge together, while the other variant uses three 3.8mm gamebit screws as well as two plastic tabs. 

Now, remove the screws using the correct tools based on your cartridge type. Once the screws are removed, the cartridge can then be easily halved. After the housing has been dismantled, remove and discard of the game's motherboard as this will not be needed.

Step 3: Disassembling the Belkin Wireless Router

Remove the two screws veiled beneath the information label on the bottom of the device. Refer to the image for screw locations if any complication may arise. Remove the screws adhering the router's mainboard to the casing. This should be rather simple.

Step 4: Preparing the Cartridge

You may find that the router's mainboard will not fit into the cartridge for quite a few reasons. The main problems lie with the unneeded plastic inside the cartridge. Specifically the long horizontal beams, the assembly holding the game board in position, and the vertical screw threading cylinder on the front half of the cartridge. Use your dermal, razor, or wire cutters to remove these cleanly. 

Step 5: Rewiring the Capacitors

Try fitting the board in once again and you'll find the capacitors are causing the cartridge housing to not close properly. These must be removed and rewired. Use either your desoldering braid or desoldering iron to remove the solder connecting the capacitors to the mainboard. Remove the three capacitors, labeled in the image, and resolder them with your wire. This is necessary for the casing to close. 

Step 6: Create Label for Cartridge

Now you can create a custom made label for the cartridge. We decided to go with a retro, Nintendo-style label for our router. Higher quality image here:

Step 7: Final Result

And this should be your final result!

    It means you will have to remove the capacitors and rewire the board a little bit. You can check out the best wireless routers in 2017 on

    I would LOVE to do this. The only thing holding me back is the Belkin router. I'm wondering if anyone can recommend a different router that would fit.

    On my website, I believe someone in the comments mentioned using a different router.

    Here's the link to the article, I can't remember which comment it was, though.

    I'm glad you like it though!

    What happened to the antenna? Does the router still give off a good sized signal without it?

    1 reply

    It's obviously not as great as it originally was, but it still sends off a fairly decent signal. We lined it around the outside of the motherboard inside the cartridge.

    would it be possible to rig something like Mozilla Firefox with the wireless so you could use the Internet on your NES?

    Such a cool idea, thank you for sharing. Heres my run. Everything went well and the router still works just as it would if left untouched. I had a friend do the electrical work and I made the rest. Fantastic logo as well, thanks for the template.. I printed with the size 650x1146 with 300 dpi. Then I used self adhesive laminating sheets (Avery 73603) to give it that professional touch. It did get a little hot but I think I'm going to make a small holes on the back to ven for air. Other than that a fun build, thanks again!

    This would be so cool if it wasn't so sad. ; )
    What poor defenseless game did you mutilate for this project?
