The N64 from France (NUS-001(FRA)) was in excellent condition, all items individually packaged and it arrived in 4 days! Amazing.

Also in the mail were a set of Nintendo security bits and a couple of carts - handy!

First step was to open the N64 up and remove the board - ive never opened a N64 - I was shocked by the number of screws!

Next locate the rare S-RGB chip, this is the chip the outputs amplified RGB - it is not present in any PAL model, except the NUS-001(FRA), the reason I had to have this console from France!

I solder 4 wires, R(red), G(green), B(blue) and Black for Sync, these are soldered directly to the S-RGB chip outputs.

Next, flip the board over, the next step is to connect these wires to the correct outputs on the N64 AV port - connecting them this way "the standard nintendo way" will allow you to use a regular SNES RGB cable without modifying it. Nice.

Each RGB line will require a 75ohm resistor (to stop the picture blowing out), I soldered the resistors first, straight to the PCB pins on the AV port

Next cut the trace to the sync on the board (see the bad job on the V Sync trace) add heat shrink and solder the correct RGB signals from the chip to the AV Output

Thats it - job done! Reassemble the N64, plug into a SNES RGB Cable and enjoy!

I have to say the picture is AMAZING! Colours are bright and vibrant. There is NO interference caused by contrasting colours, everything is sharper! Perfect!

I took a couple of snaps of Zelda, before mod and after - unfortunately the photo's haven't come out very well (iphone camera). Ill use the SLR and get some better photo's another day, as now im off to enjoy the best possible picture quality on a PAL N64.

Total cost : £40 for french N64, 3 games, 1 controller, £1.24 for resistors. 

Quest completed :-)
