Re: YPbPr ouput mod for SNES consoles
Ok. It's good that you say an amp on both Red and Blue should fix things. Just one lingering question. The Reds, Pibks and Oranges are very intense. The best example is that the Red Koopa orange face and red shell almost blend together. Can I simply use a higher ohm resistor to try and bring that le...

Re: YPbPr ouput mod for SNES consoles
If I remember correctly, the component pins on the SNES RGB->composite converter are both 1- not really rated to source current and 2- brought back into the same IC to create composite and s-video chroma. Hence the problems you're seeing, and why everyone else has been throwing opamps at the proble...

Re: YPbPr ouput mod for SNES consoles
So I finally picked up a decent CRT to test my SNES on. A 2004 Toshiba 27". I really wanted a 24" Sony Trinitron WEGA. But beggers can't be choosers. Anyways my red is too intense. I'm not sure if I should add a higher resistor to the final output from the red amplifier or to remove it. I'm kinda si...

Re: YPbPr ouput mod for SNES consoles
I think lidnariq is asking you to plug your SNES's composite video cable into the TV, but set the TV to component input. If it works properly, you'll get a grayscale picture with a weird moving checkerboard pattern that looks like this . (If the TV won't let you select component, or isn't grayscale...

Re: YPbPr ouput mod for SNES consoles
What happens if you tell the TV to parse the SNES's composite output as component Y? In any case, the TV really should have been ok with the SNES's s-video luma output. Do you have another 240p source to try with? (Maybe a Wii playing some virtual console game?) I'm not sure what you're asking abou...

Re: YPbPr ouput mod for SNES consoles
Does the image still shake if you just connect S-video luma to component Y (leave Pr and Pb disconnected)? Or does the TV refuse to parse that as component and pretends it's composite? (maybe hook up something else's PrPb source if it does think it's composite?) Well if this helps, I put the Source...

Re: YPbPr ouput mod for SNES consoles
So my parts arrived today and I rebuilt the amp. Here's the old amp I used: http://i237.photobucket.com/albums/ff216/Sephiroth1975/General/EarlySNESYPbPrCircuitAmp_zps99c7a3aa.png Tried using the 2N4401 with the schematic you posted for the S8050, actually got some results that were not black and w...

Re: YPbPr ouput mod for SNES consoles
A TV with component but not S-Video? That's confusing. (But I believe you, I'm just confused by it) A s-video to component converter might be reasonable? Google seems to suggest DVD recorders are probably the cheapest way to get the encoding converted. S-Video doesn't come on many TVs anymore. My g...

Re: YPbPr ouput mod for SNES consoles
I am looking for a "Its simple and works" mod. Is there a reason you're skipping the very simple RGB out? Most editions of the SNES natively have RGB on the AV multi-out connector on the back. If yours doesn't, http://gamesx.com/wiki/doku.php?id=av:snes2rgb and http://gamesx.com/wiki/doku.php?id=av...

Re: YPbPr ouput mod for SNES consoles
Hey everyone! So... I know a lot of you guys are working on technical things to try and make the best possible YPbPr mod. I am looking for a "Its simple and works" mod. I just tried taking the 3 Pins off of the S-ENC (9328) encoder chip to RCA jacks and got a white washed picture that shakes on my P...
