Everdrive N8 : DIY Cartridge Shell Fitting

What's the Everdrive?

The Everdrive N8 is capable of running NES games, software and even 8bit music tracks from a SD card. Basically this is a SD card to NES adapter!

This is the ideal alternative for game developers, chiptune musicians and a way to play legal backups of collectable cartridges. Many retro gamers prefer to play NES games on the original hardware. This adapter opens new possibilities with translated Japanese games and newer fan based developed games. This unit will  also extend the life of the NES and your beloved cartridges.


Fitting the Cartridge.

In order to save a few bucks many purchase the Everdrive without the cartridge shell. This page will illustrate the modification needed in order to fit the Everdrive yourself.

1. Before getting started you'll need a 3.8 Security Bit. This bit is a worthwhile investment for retro gamers. This tool opens NES, SNES, N64, and Game Boy game cartridges! Locate the screws on the back. Look for the more common 3 screw versions, 5 screw carts are older and more collectable. Once the cart is open locate the tab illustrated in the photo below.

2. This center tab needs adjustment before the Everdrive can lay flat. The backing of the center tab needs to be removed.  I used a Dremel tool with the sanding pad.  Note: This mod is not needed for the older 5 screw cartridges.

3. Assemble the cart and take note of the SD card location. Measure twice cut once!

4.  A simple flat file is the safest method. Slowly file away the extra plastic

5. Make sure the SD card can easily move in and out of the new slot. Once completed reassemble the cartridge. You are done!

  1. Can you recomend an online store where the Everdrive N8 can be found.

    1. Cheapest and my personal favorite is RetroGate. This is straight from krikzz the inventor. Prices are good but expect a 2 week delivery time for USA customers.
