Alright I am looking to complete this mod but am having some issues. My main one seems to be that I can't locate a place to buy the component female ends. Is there a place to get these somewhere out in the wild/online? Also is there anything additional that I need to make sure my SNES has? I just want to be completely sure before I start this little adventure.

Here's some real classy RCA jacks on Mouser.

They're kinda expensive, but look so awesome. Here's my own Component SNES with those jacks:

These are EXACTLY what I am looking for. Thank you so much! Now I just need to buy some wire. Any tip or anything that I should probably think about while doing this mod? Also how do you feel the picture improves over S-video?

I used 28 AWG braided insulated wire for my SNES. You could try thinner wire but I don't know how it affects picture quality.

One good tip is to be careful when soldering to a surface mount chip. It can be easy to accidentally add too much solder and bridge legs, or make cold joints. Here's a picture of my SNES, with the wires soldered to the S-ENC chip (the one that doesn't need external parts for component to look good):



Also, speaking of the chip itself, you should open up your SNES and check to see which encoder your SNES has. If it's the S-ENC, then only three wires and three RCA jacks are needed to get component. If you have the BA6592F chip, then you'll need some extra components before the video is suitable. I don't have that information on hand unfortunately. I think Ace on Sega-16 posted a schematic for the BA6592F which shows the parts needed to stick on the component outputs on the chip.

Component and S-Video share the same general clarity and crystal clear picture, but Component's colors have more vibrance and definition. S-Video tends to look a little washed out in that regard. For instance, greens look more greeny on Component.

I don't know anyone who can do a service like this. I suppose I could but I'd have to order more of those jacks and I'd have to live in the US, since most people can't stand the shipping costs to Canada.

Thankfully I am rocking the S-ENC chip in my color modded SNES. S-ENC BA6594af is my chip code. So that means I only have to go three wires? Thats really awesome haha, one more quick question. If I were to not go with the above links. Would any old phono plugs pretty much work?

Has any one seen a breakout box with this type of connector? I'm thinking something similar to what came with older ATI video cards: a small box with the RCA connections on it with a single cable going to the PC. I'd rather have this than the RCA connectors right on the case.

Now that I think about it, I could probably just use an ATI cable. It's even purple to match the Nintendo color, although the connectors are red/white/yellow.

Yes, any phono jacks would work. The coloring is simply for convenience. I've used composite stereo cables for component lots. Heck, here is what my SNES looked like before I bought those component jacks:

You're thinking of a Mini-DIN connector, like on Sega systems. Most people go with RCA jacks because they are easy to get cables for. Multi-AV type connectors sometimes need custom cables built in order to be used. If you went with a 13 pin Mini-DIN port, you could put stereo sound, composite, s-video, component, RGB, sync, ground and voltage on the same physical connector. Problem is, I don't think you can easily get most Mini-DIN ports in panel mount packaging. Perhaps the best option would be to remove the RF modulator, then glue or solder your PCB mount connector to the PCB itself.

I took this approach when I modded mine, I didn't want to drill new holes in to the back of my console. So I removed the RF output and mounted this in its place. 



EDIT: thought I would add this link. http://www.nintendoage.com/forum/messageview.cfm?catid=22&am...

Such a slick mod. That's exactly what Zing probably had in mind.

I'm happy enough with the RCA jacks though, pretty happy with myself over the uniform and even arrangement too.

Anybody have a more detailed how to? I really want to do this but I don't want to mess anything up.

How more detailed can you get? If you have the S-ENC, just solder wires to the pins shown in the one picture I posted, then attach those wires to the RCA jacks. Don't forget to wire in ground for each jack.

If you have the BA6592F, then things get a little more complicated, yes. First off, this post has Ace's schematic, it explains what components are needed on the component outputs:

http://www.sega-16.com/forum/show...

Going by that schematic, for the Y signal (green), which is pin 23, you need a C945 (or 2SC945) transistor, with a 147ohm resistor.

R-Y (pin 1) and B-Y (pin 24) (red and blue) also use the same transistor, but two resistors are needed. You need a 33 ohm resistor on the transistor, and a 1k ohm resistor tied to ground. Between those two resistors is your video output for both signals.

After adding those components, all that's left is wires, RCA jacks and ground wires for the jacks.

I bought all the supplies and realized that I don't have the s-enc chip. Time to buy some more crap... or to buy another random snes!

What chip do you have? This should work for 6592, 6594, s-enc,

I have the BA6592F and I need to build the thingy from the schematic since I can't attach the RCA connectors directly to the SNES ENC. There's no room to put it in the SNES however (or is there?). It seems quite complicated.

Also, I haven't soldered since 1999 when I got a modchip for my PSX. 

Did you have to build the signal booster?
