An unmodified NES only supports composite and RF (radio frequency) video output. The NESRGB is an internal mod that adds RGB and S-Video video output to the NES and Famicom.

The mod features a user-selectable palette system that allows the user to change the color scheme of the video output to suit their preference. For more information about NES palettes, see FirebrandX's NES Palette Project page.

  • Generates RGB, S-Video (encoded from RGB), and composite video (encoded from RGB) signals
  • No latency (video timing is maintained)
  • Built in audio and video amplifiers
  • Compatible with NTSC and PAL consoles
  • Compatible with NES, Famicom, AV Famicom, and Twin Famicom consoles
  • User selectable color palettes
  • Upgradable firmware via JTAG programmer

Technical Details

The NESRGB board contains an Altera CPLD (Complex Programmable Logic Device) that utilizes the NES's PPU (Picture Processing Unit) and CPU to generate an RGB video signal.
