Quote from: SlumberingWeird on June 05, 2020, 10:26:40 amI didn't order the RF or power cords with the system, and having PAL TVs is a nightmare enough so I figured AV was just the best option as I definitely have spare cables lying around.
Quote from: FAMICOM_87 on June 05, 2020, 12:09:59 pm1) just use 2 wires for audio jack and 2 wires for video ,that all2) the wattage does not meter, use the tiniest one resistor like 1/8 W is enough 3) the Audio is always in pin 46 from the cartage slot on any revision, but the video is not, you have to trace it down from pin 21 on the PPU4) yes it is very simple , there is a slightly complicated scheme with one additional transistor, but is can work on any famicom NES or famicone even NOACs here https://drive.google.com/file/d/1EQRmeMO1W0WFJ3EWKj9Z5l3DMet4eLTV/view?usp=sharing
Quote from: P on June 05, 2020, 11:38:06 pmThe PPU is the video chip in the Famicom designed by Nintendo, possibly inspired from Namco's Galaxian arcade system (which inspired Nintendo arcade systems like Donkey Kong) and common video chips like the TMS9918. It's sprite- and tile-based and is what gives games the characteristic Famicom look.Even if your TVs support 60 Hz framerate and NTSC colour encoding, chances that they support NTSC via RF are low. Or did you already test RF?
