The N64 doesn't output RGB video, only encoded composite video and s-video is available on the A/V output port. It's best to use RGB video for the best looking picture. This board can be installed into any model of Nintendo 64. Digital signal from the from the graphics processor enter one side of the N64RGB and analogue RGB video comes out the other side.
The board is a revised, commercial version of my N64 RGB DAC project created in 2007. This version has several improvements over the old design. Lower power consumption, correct pixel alignment (looks less blurry), support for different cable types, and the components are all mounted onto a PCB this time.
The board supports both (PAL) Super Nintendo RGB SCART and Gamecube RGB SCART cables.
The board is easy to to install for anybody who is experienced with soldering and following instructions.
