    Hello, I was wanting to do the RGB mod on a model 2 Genesis. Mine has the Sony CXA1145M chip for converting the graphics, and it outputs RGB on pins 23, 22, and 21 respectively. They each run to a separate hole as seen here:

    So technically, shouldn't I be able to put a wire through each hole for the different signals? I tried this and got no signal when plugged in to my TV. I'm not very skilled when it comes to circuitry, but if needed, I can solder some stuff. I don't however really want to solder directly to the pins, because I am not that skilled; the highest level soldering I've done was disabling the 10NES chip in my NES. Any advice would be helpful. Thanks in advance!

    I used those same vias aka those holes but you will likely have to scrape lightly using some form of blade the copper or brown circles a bit so solder can stick to it.

    RGB is not component. It almost never works on US TVs.

    Still Genesis 2 already outputs RGB, not usually much point to this kind of mod.

    I thought component and RGB were the same, the R output goes to the red connector and so on right?
    Why wouldn't it work on US TVs, but would in other places?
    And how does it output RGB? The only output is composite.

    Basically, how would I do the RGB mod? I've seen quite a few for S-Video mods, but none of my TVs support S-Video. Also I looked for an S-Video to component converter, but none of them were for 4-pin S-Video, they were 7-pin.

    No. Component has only three pins (often called YPbPr).
    RGB needs four at minimum. Red, green, blue, and sync, not counting a signal voltage many European TVs expect.

    Sega provided RGB at the rear DIN. You probably noticed the DIN has like 8 pins, far more than used by composite.

    oh alright, is there any way to tap into that and connect it to my tv for a clearer image?

    A sega model 2 outputs rgb out of the box so no need for a mod.

    Since you lack scart your best bet is to get a rgb to component converter.

    Or have someone mod your system for component video.

    In any case for component, it's easiest to use a CRT SDTV.

    HDTVs that reject 240p video from component also need upscaling.
