## Note on RGB and HDMI:
Neither RGB nor HDMI video output were or are a goal of the OpenTendo project, the goal was/is documentation and preservation, and the project was an exercise in reverse engineering. As such "improved" video outputs will not be added to OpenTendo.
NESRGB and Hi-Def NES can be installed as normal, but will not be incorporated into the OpenTendo PCB
