Things you will need:
1 can of spray paint (I chose a metallic gold)
1 can of plastic primer
A rotary tool (helpful but not really needed)
A few sheets of sandpaper (320 grit or higher)
1 can of high-luster lacquer
Step 1: Disassembling your N64
It is pretty simple. All you have to do is find a hard plastic pen (mine was a Pilot brand), unscrew the back, melt it a bit with a lighter, and jam it into the screw hole. After you have let the pen cool off for a little bit, it should now be nice a mold of the security screw, and you should be able to remove those annoying little screws without much problem.
You are going to need to do this several times because the plastic screwdriver you just made strips very easily. Also, you might find it helpful to have a piece of tin foil to roll your melted screwdriver on should it mushroom out too wide to fit in the screw holes.
Step 2: The Innards
Once you have detached all of the innards, set them someplace safe for later.
