AHA! Just figured out why I'm lost here. See, the reason that I "AV Modded" this here Famicom was because the original model only output RF Modulation .
This "MOD" that I did to it was to enable a composite video output. I built the circuit that does composite video. So I can't change the famicom's composite output-- It doesn't HAVE one! ^^
Okay, any other suggestions
