FIxing a NES motherboard with c0pperdragon PPU digitizer

This NES had corrupted graphics after an attempted c0pperdragon PPU digitizer install. The digitizer captures all of the signals going into the PPU (the picture processing unit) and convert the video output to Lumacode, which is a composite video signal that allows for a pixel perfect decoding of the video image by a device like the RGB2HDMI right from devices like the NES which normally only have a noisy NTSC or PAL composite video signal. Let's fix it -- and then try to fix the PPU digitizer, showing off how terrible my SMD soldering skills actually are.
