    Great points. Thanks everyone :P. Someday if/when I'm loaded and if TV technology has never caught up to the majesty that is CRT technology, I will perhaps buy the XRGB equivalent of the day, if one exists O..o

    RGB under ideal circumstances wildly beats anything else. That is no myth or hyberbole. However it takes extra TLC to gain its full benefit. RGB is the purest sharpest option in existence, raw video format many consoles render in. Any minute artifact WILL be visible. Especially on HD sets. Has none of the "smoothing" effect, that CRTs and/or composite provide.

    In my RGB modding experience I found that the SNES' RGB was the best out of the older consoles I own. Quite stunning.

    However, S-Video Monster Cables (SNES/N64/NGC) will work pretty well for screen capturing because their superior build quality, as compared to other S-Video cables, allows for a much better picture on that format.
    The accumulated filth of all their sex and murder will foam up about their waists and all the whores and politicians will look up and shout "save us!"......and I'll look down, and whisper "no."

    I've gone through about all the internal hardware revisions on the original SNES and they all have poor RGB picture quality, some are better than others, RGB on the original model SNES is very blurry for some reason. Every Super Famicom I've come across has the same problem.

    The SNES 2 or Super Famicom JR. on the other hand, when properly modded offers the best RGB picture (it does not output RGB out of the box). A huge improvement. I prefer the look of the original SNES/Super Famicom, but use a Super Famicom JR. because of the much better RGB picture quality.

    I use a Sony standard res. RGB monitor, but the difference in picture quality can be seen on everything from RGB/Component converters to the XRGB units.

    As for Genesis, it's been proposed (if largely rumor) jail bars might be a VDP problem. Curing that entirely will take re-implementing an improved graphics chip to fix the bug. Good luck finding someone with transistor skills or a semiconductor plant...

    I don't get Jailbars with my own RGB cables, only had problems with cheap cables that are missing the components that are necessary...

    the jump isnt huge, but it is with the genesis. i purchased a scart -> component adapter for around 50 bucks. with that adapter and a scart switchbox, i had space for 4 different scart connections. the scart cables themselves werent that expensive so i bought cables for the genesis, snes, saturn, and neo geo. the entire setup was around 120 dollars. the jump in quality for the saturn and snes (s-video) wasnt huge, but it certainly was for the genesis and neo geo.

    Hate to bump an old thread, but I've been thinking about this recently and I'm trying to figure out why this is. Perhaps the SFC and SNES use composite video for sync instead of a proper sync signal?

    I doubt it has anything to do with that, on the model 2 I have my monitor is taking sync off of the composite video line, looks great.

    In fact a while back I bypassed the RGB/Video encoder on a model 1 PCB I had laying around, and installed an RGB amplifier, the picture looked a bit better but was still soft. Looks like the PPU is outputting the video that way... didn't look at it with a scope.

    It might be. I'd suggested earler in this topic RGB quality issues could be part of the hardware for Genesis.

    I hadn't even considered SNES... But don't see a particular reason to rule out the idea, now that it's on the table.

    I concur with Hamburglar in that the SNES' RGB isn't as sharp as other systems like Genesis, SMS, PC-Engine, Saturn, etc. The SNES has a bit of blurring/trailing capacitance on the right side of high-contrast objects that the other systems don't have. (I can't speak for the SNES Jr.)

    The S-Video on SNES is clear enough that RGB isn't absolutely justified. I don't have S-V shots but my page here does have some composite-RGB comparison shots: http://www.chrismcovell.com/gotRGB/rgb_compare.html

    Yeah, with the monster S-Video cables my video quality is every bit as sharp or sharper than the RGB screenshots that guy is showing. I've used crappy S-Video cables before and their quality wasn't half as good as the monster cables.
