I made my N64 capable of playing Japanese games and gave it a fresh new look.
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
A lot of companies have a nasty habit of making it hard to take apart their products. Nintendo is very guilty of trying to crush the DIY spirit. But, we will prevail! Why? Because their tamper-proof screws are not so tamper-proof. You can go online and buy the proper screwdriver, and spend money, OR you can use a pen and a lighter to get past those stupid screws.
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.
