N64 RGB Mods
All versions of the N64 can be RGB and HDMI modded. The UltraHDMI board works with all versions of the N64, however there are a few choices for RGB.
“Advanced” N64 RGB Kits – Compatible with all versions of the N64
Every N64 can output RGB using an “advanced” RGB kit, which are generally more expensive and harder to install, but offer extra features.
At the moment, the best “advanced” RGB kit is called the “N64RGB” and made by Tim Worthington (creator of the NESRGB and 2600RGB mods). The video quality is excellent and you can even download custom firmware that allows for “de-blur” options.
Here’s links to Tim’s installation guide: http://etim.net.au/n64rgb/instructions-new/
You can purchase this board directly from Tim: http://etim.net.au/shop/shop.php?crn=209&rn=548&action=show_detail
There are a few other N64 kits in development. I’ll update this page as soon as they become available.
“Basic” N64 RGB Kits – Only compatible with earlyversions of the N64
Early versions of the N64 (the first 4 board revisions) can output RGB with a board that offers the same video quality, but is much easier to install and less expensive. There are a few tricks to find compatible N64’s, but the only way to be 100% sure is by opening it up.
How to find RGB-outputting NTSC N64 Systems:
– If you have a serial number that starts with “NS1” (USA), “NUJ1” (Japan) or French systems with the model number “NUS-001(FRA)”, then you most likely have an N64 that’s compatible. Supposedly, some early Canadian N64’s also contain this chip.
– Many older Brazilian N64’s contain the same chip and can be RGB modded. Even though Brazil used PAL-M, is was still 60Hz and only compatible with NTSC games: http://s9.zetaboards.com/Nintendo_64_Forever/topic/7405289/1/
– If you have a serial number that starts with anything else, or is a PAL console, you’ll need to use the “advanced” kits described above.
– For more information on which serial numbers have each motherboard revision, please visit these sites:
Confirming the correct chip:
Regardless of serial number, please open your N64 to double check that it has the correct video chip that’s required for RGB-modding (explained below). To open the system, you’ll simply need a 4.5MM game tool and a philips screwdriver, as described in the tools section.
– First, remove the memory module, then unbolt the plastic cover using the 4.5mm game tool. Then, unbolt only the screws that are circled in the picture below. After removing just those, the entire metal heat shielding will lift off as one piece, exposing the motherboard:
– Once it’s disassembled, look for the following chip. If it says “VDC-NUS” or “VDC-NUS A” (like pictured below), you should be fine and can proceed with the basic RGB mod. If it doesn’t have this chip, you’ll have to use one of the advanced mods.
Where to purchase?
If your N64 is compatible with a basic mod, you can either make your own RGB amp board, or buy one pre-assembled. I strongly recommend the pre-assembled ones, as they generally use better amp chips (THS7374 vs 7314) and some offer more features like a sync stripper.
