First step is pretty simple. Take your gameboy apart. For this, you'll need a tri-wing screw driver. You can get one from many different sites, but I recommend Kitch-Bent and Nonfinite Electronics. Once the case is apart, you'll have to pull out the ribbon cable that connects the two PCBs. Just give it a gentle tug, and it will come right out. You'll also need a smallish Philips screw driver to take the PCB's out of the case. There is also a metal bracket behind the cartridge slot that needs to come off. You also have the option to take off the screen cover, but if you choose to do this you'll have to do some extra work scrapping off the old glue and re-gluing it back on. Otherwise you'll just cover this with tape, which is what I did.

The cutout stencil
Now, as I stated, the front part of the case has two colors. I decided to make an 8-bit skull design. First, I drew my design on paper and cut it out. Once you have the paper stencil, layout two layers of painters tape on a piece of cardboard that is slick, like a soda box. I used a Long John Silvers cardboard pirate hat. then put your paper stencil over the tape and tape it down with only one layer of tape. You should be able to see the stencil through the tape. Use a razor blade to cut out around the stencil. Once you are done with this, remove the unneeded tape and the paper stencil, which now has one layer of tape on it. You're now ready to take your knew double layered tape stencil and put it on your gameboy!
The gameboy with the new stencil on
Now you're ready for your last coats of paint! Do your best to make sure that all of the edges and corners of the stencil are stuck down as best as you can get them. Then, you are ready to put on your second color. Apply just as you did your base coat and then apply a couple coats of clear coat to protect the finish. After that, you're all done! You can either put your awesome gameboy back together, or continue to follow the blog for the next part which is going to deal with hardware modification. Keep moddin' chippers!
