Step 1: Obtaining your N64 + PulseVu 2x Chip
Same as the pulseVu chip....simply go on ebay and search for one and your on point.
The pulse vu 2x chips is what is being used in this tutorial.
Step 2: Take apart your N64
Use a 4.5mm Gamebit Screwdriver (or look up the pen hack) and take off the the bottom screws.
Now that the inside is exposed, used a phillips screw driver and remove the many...lol....screws to expose the motherboard.
