N64RGB - Nintendo 64 RGB video board

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 all kinds of RGB cables. PAL and NTSC Super Nintendo RGB SCART, Gamecube RGB SCART, Super Famicom Japanese RGB21, HD Retrovision, and RAD2X cables.

The board is easy to to install for anybody who is experienced with soldering and following instructions.

Boards sold after 27/12/2016 now come with software v1.1 which includes an optional 'de-blur' feature. This gives the video a pleasing sharp pixel look. Version 3 (sold from 18/5/2022), also has this feature along with an in game reset and component video output.

Version 3 specific info

To enable de-blur via the controller press Z + Start + R + C-left. To disable press Z + Start + R + C-right. The state is reset to default on power cycle. If the SW pad is unconnected de-blur default is off. If the SW pad is connected to ground (GND) de-blur default is on.You can connect a switch to the SW pad and toggle the feature this way if you like.

To reset the console in game, press Z + Start + R + A + B.

Jumper JP4 controls the low pass filter on the RGB output. Open = enabled (recommended). Closed = bypassed.

Jumper JP5 selects output type. Open = RGB. Closed = component video. When in component video mode Red = PR, Blue = PB, Green = Y.

Jumper JP6 is for the data monitor (blinking LEDs). Open = enabled. Closed = disabled.

Jumpers JP7 and JP8 should be left open.
