    with Csync as composite video will it be sharp output like the component mod or output video similair to the official snes cable?

    It will be sharper because its pure sync, unlike composite video which is a mix of everything. I think the official cable uses composite video for sync instead of C-Sync.

    Bp is blue so im guessing that instead of tapping Bp on pin 23 i just tap pin 3 Csync for that signal ?

    I'm confused. Can you explain what you are trying to do again? Are you doing a component mod? If so, i dont know how to do that mod as I use RGBS via SCART and a SCART to HDMI converter.

    Yes, the XRGB mini is an amazing device from what I've seen. It will be solderless too as you can use that official cable without modifying it. I recommend going that route as it would be much easier than the component mod. It is expensive though.

    Because composite is present on the SNES and it's the correct signal to use.

    Also, actually it's the other way around - for C-Sync you can use C-Sync, composite or Luma.

    so with C-Sync its good for VGA or HDTVs ? as for Luma good for YpBpR? and Composite just the standard connection the system uses ? so in the end its best leave the system alone and xRGB all the way i read its amazing not only for SNES but several other systems aswell :D looks like imma have to add that to my list of things to get :)

    C-Sync may work on VGA but very few monitors support that. Luma is the Y in YPbPr. The green jack doesn't carry green video info. The TV fills in the green info. The green jack instead carries Luma.

    The XRGB mini would be a much better option. Since no mods would be needed to use it.

    This is obviously very, very wrong. RGB is ALWAYS vastly superior to composhite.

    If Bacteria has experienced a better video quality using composhite he's doing something wrong. I'm not trying to be condescending, just stating the facts :)

    Back on topic: To get the best picture on your VGA monitor, you should consider getting a linedoubler that takes RGB and outputs VGA. Something like the XRGB-2+ or 3 will work great. And it will look good too, unlike the suggested composhite to VGA converter suggested above.

    I know my modding credentials but not yours; are you an experienced modder Bearking? I have experience with consoles and modding them and have seen the differences between systems video outputs. Yes, on most systems composite isn't great, and on some (eg Turbografx) come of the colours (eg yellow) come out totally wrong), the N64 however has a very good composite, RGB is a bit better but not greatly, and in the case of the SNES, I have tested in the past with composite vs RGB and actually comparing both together composite looks marginally better, also RGB on the SNES comes out a bit dark whereas with the composite a 38ohm resistor composite to ground, gets the level right. So yes, on the SNES, composite looks better. I've tried it. Only other console I found with excellent composite was Core-Grafx which again seems so close to RGB that there isn't benefit.

    I have a couple of component modded snes's and can say it looks way better than composite when doing a comparison on my crt.

    I haven't shown off much here. But I made the consolized PSP a while back. I've been modding for the last 6-7 years or so.
    Here are some pictures:
    http://s40.photobucket.com/user/Konsolkongen/library/Various mods?sort=3&page=1
    (I'm well aware that the older mods look like crap)

    Also here's some more recent stuff I did on commission:
    http://s40.photobucket.com/user/Konsolkongen/library/Various mods/Rumaben?sort=3&page=1
    http://s40.photobucket.com/user/Konsolkongen/library/Various mods/SofticeAllan?sort=3&page=1

    http://s40.photobucket.com/user/Konsolkongen/library/Various mods/slk486?sort=3&page=1

    However I fail to see what modding skills have to do with the native RGB picture most Super Nintendos output :)

    Have you checked the links I posted? RGB is clearly superior. As it's been on all SNES variants I've ever modded (originals, 1CHIP and SNES jr.).

    Maybe you should change your CRT :p
    Composite SNES is blurry, red are fuzzy. Quality will always be better in RGB than in composite, as the latter is created using RGB. Some games on NES may look better on composite because it allows some sort of dithering.
    N64 is also way better in RGB than in composite.

    For the SNES, I'm not using modded console, just plain SNES with good old SCART :)

    Are you using a PAL SNES by chance? I haven't tried one to say if their composite has less color bleed.

    Yes, only version of SNES I have used is the PAL one. It is likely the NTSC ones may have better video output especially later editions. Wasn't being a dick BTW, I phrased what I was asking though in a poor manner, apologies! It's just it is not unusual for someone with little or no modding knowledge to pass themselves off as an expert yet in reality only give bad or false information, so always a good idea to check if someone is rehashing information or they know their beans! :oops: When I started modding, I took various advises from people as such and wasted money and time as a result.

    Seriously? You think I'm giving bad and/or false information? You really have no idea what you're talking about. Have you even looked at my links? They clearly prove that there's a huge difference between RGB and composite.

    Please look at them. And have the courtesy to admit that you were wrong.

    I don't care what it may or may not look like on your HDTV. Because most HDTVs make even RGB look retarded. The fact is, that comparing the two signals on a CRT, or a using a good upscaling-device on your HDTV (your noname RGB to HDMI converter doesn't qualify), there is just no contest. RGB is always better.

    EDIT: And once again, please explain to me why modding has anything to do with SNES RGB, when most systems will output this natively...
