I developed a rather simple mod that allows you to use a PAL (and probably american, but haven't tested) FourScore, allowing you to use NES controllers on the Famicom without the need to butcher FourScores for their plugs. Furthermore it allows you to play fourscore compatible games and use the turbo feature.
I tried creating an automatic system without luck as there is no easy way to detect a fourscore being plugged in. Also tried getting the Zapper to work but it doesn't work due to the chip used in the FourScore.
