This is the kind of project that you are going to do because you are bored. You will not need to do this project ever. This is just for entertainment. So. Materials required:

MaKey MaKey

Any small cardboard box(max 7x7x7)

At least ten alligator wires

Tinfoil

A hobby knife

A Mac(Windows may be possible, I don't know.)

OpenEmu Experimental(software)

ROMs to be emulated

Time required: 15-30 minutes

Have Fun!

Step 1: Assembling Materials

This project WILL NOT be very organized. At least, the inside of the box won't be. So make sure you have everything. Pretty simple, right?

Step 2: Cut Various Holes

You will need to cut at least seven holes in your box. Five for the buttons, one for the ground lead, one for the line to the computer. Or you can thread the wires through the lid. Again, this is a simple step, but it's very important.

Step 3: Making Buttons

You will need five buttons. Up, Down, Left, Right, Fire. The buttons should be a maximum of 1.5"x1.5". Also, you should probably make a bracelet out of tinfoil while you're at it. The buttons should have little pointy bits on the bottom to go into the holes. Fold tinfoil into an appropriate shape and out int into a hole.

Step 4: Connecting the Buttons to the MaKey MaKey

You will need your alligator wires for this. You should, INSIDE the box, attach one end of the wires to the pointy part of the buttons. Attach the corresponding ends the the corresponding holes.

Space = Fire

Up Arrow = Up

Down Arrow = Down

Left Arrow = Left

Right Arrow = Right

Also, attach any part of the bracelet to any of the 5 ground(Earth) holes.

Step 5: Setting Up the Software

Download OpenEmu Experimental Version from here: https://github.com/OpenEmu/OpenEmu/releases/downlo...

Download Atari ROMs from here: http://www.emuparadise.me/Atari_7800_ROMs/47

Drag the ROMs from your downloads folder directly into an OpenEmu window. They should install.

Step 6: Finishing Up

Hit command-comma to bring up the OpenEmu preferences. Go to the controls tab and select Atari 7800. Change the controls so that they match the list in step 4. The other controls won't matter.
