I built a cable to go from SCART to the 25pin DSub on the back of my PVM-2530. PSX and Genesis look great (besides the jailbars)!
My NTSC SNES tooks waaaay too hot (though it looks fine through My XRGB-2+) ?????
Here's S-Video

and now RGB

I opened the SCART cable (bought it from eBay, and works with an XRGB-2+) and it has 220 caps, which I believe is correct.
Any idea what's going on here? Do I need to add resistors as well? To what lines, and how much? 75? 100?
OK, turns out there was a capacitor on the sync line. I removed it and there was no difference.
Then for kicks I removed all the remaining caps (RGB).
*drum roll*
No difference. Absolutely identical to what I'd had before.
Ideas?
Do you have a PAL SNES? If so, you'll need add 75 ohm resistors to the RGB and sync pins.

Sorry, no--didn't mention that. I have an NTSC SNES, Serial #UN10343021.
Fixed it with help from another forum. Thought I'd post the solution here for anyone looking in the future.
There was a cap on the sync line that I removed--no difference. Removed all the caps on RGB--no difference. Turns out the caps on RGB were the wrong direction!
Redid the caps--sent (-) to the SCART pin and (+) to the wire. Fixed everything.
Loving the RGB! :D
Haha, yes, the + side should be oriented towards the transmitter (ie: where the + is coming from) and - goes to the output (ie: receiver).
Glad you worked it out.
