Step 1: Materials
Two-Button Optical Mouse (without scroll wheel)
optional (Heat Gun and Razor Knife) for cleaner cuts
Step 2: 1. Take Apart the Mouse
Make sure you don't mix up the parts.
Open up the mouse and take out its guts. Keep them.
Throw away the case.
Step 3: 2. Take Apart the SNES Controller
Step 4: 3. Grind Down Plastics
You have a top and a bottom.
They will need to have certain parts ground down so the mouse guts will fit inside.
It is as follows:
Step 5: 4. Cut Hole for Optics
One problem you need to cut a hole in the bottom of the SNES case so the optical part of the mouse will work.
This is where you cut.
I used the cutting blade on the dremel tool.
You can also use a heat gun and razor blade if you have access to these.
My cut is quite crappy but it will do.
Step 6: 5. Glue
Careful not to glue your fingers, use tweezers if you are bad at it.
Step 7: 6. Mount Mouse Into SNES Case
Don't put it in backwards!
Now place the bottom part of the SNES case on the back.
Glue the topmost corners together along with sticking in two screws that are located on the right and left. (they are the only usable threads left, its not hard to figure out).
