SNES Component Out Mod with S-ENC B Chip
<< < (3/3)
wiggy:
I have not done one myself, but I've seen the results in person side-by-side with a 1chip hooked up via S-video and I still say it ain't worth it.

Though I have no idea which revision of the SNES it was and the exact method used to modify it.

There's that one company who makes component cables for the SNES. Can't recall the website at the moment, but it's been posted here before, I do know that.

If you're saying that, you haven't done it yourself.

I did it to my original S-ENC SNES and the results are fantastic. Better than RGB from the same model SNES (the early SNES's have very soft RGB).

I did not use the circuit in the OP with a transistor. I simply connected Pr and Pb with an inline resistor and capacitor on each one (I don't recall the values but I also didn't try multiple combinations so my values may not be the best). The Y is already available from the multi-out. I removed the RF encoder and put a TRRS jack in its place, and I use a YPrPb dongle that are easy to find online.

Note: The picture will still be 240p and look like garbage on LCD TVs. Use a CRT or XRGB, although I have seen a lot of sync problems with component on XRGB.

Can't sleep, so figured I'd just go ahead and mod a SNES with your method.  I think that was the quickest and dirtiest mod I've ever done.  I didn't make it pretty. Far from it in fact. But it works from a technical standpoint :P I'm even less impressed at this point. Colors look like poop, just as I recall and the image is maybe, possibly slightly sharper with the component mod, but nothing that is significant enough to offset the awful color output.

Ignore the red bars. I don't know why they appear in the photo, but they aren't visible in person.
