Welcome to my first Instructable, I will tell you how to make a Nes money bank only using

A small flat-head screwdriver

A nes game of your choice

Scotch Tape (I think duct tape might work.)

Step 1: Take Out Screws.

Take out all 5 screws on the back of the nes cartridge with a small flathead screwdriver.

Step 2: Tape It.

You will now notice that the cartridge split into 2 halves. Put Scotch tape on both halves so they connect. Use a lot of tape. Put one piece of tape on the right side to stop it from opening.
