Taking a close look at the composite video signals on the NES frontloader, and doing some super simple mods to improve the video output. All we need is a 75ohm resistor, a 2N2222 transistor, a 1nF capacitor (or there abouts) and a bit of wire. We'll also do the Famicom expansion audio mod while we're at it.
