Quote from: undefinedI am beginning to think that the little circuit on this French N64 was only there in order to maintain 'backward compatabilty' with the French SNES Scart cable.Simply put, the originally planned video components for this French N64 were designed to work only with PAL SNES video cables (Which use 75ohm resistors to ground) Its not the layout the 'S-RGB A' chips datasheet would have recommended, its what Nintendo had to do to maintain backwards compatibility with PAL video cables.The NTSC method would be preferrable since it is the 'correct' method, its the layout the 'S-RGB A' chip was actually designed for, and is likely exactly what would have been recommended in the datasheet. It also means you could use 'standard' RGB cables with 220uF capacitors on R, G, B.
Quote from: ApolloBoy on March 05, 2014, 06:22:16 PMSince your N64 uses the same encoder as the SNES mini and 1chip SNES, adding S-video should be a fairly easy process. As I've stated in the wiki, you can add 75 ohm resistors (or 100-150 ohm if you find the resulting image is too bright) to the chroma and luma pins of the encoder and that should do it. The 220 uF cap for luma and 100 nF cap for chroma are optional but it won't hurt to have them in.
