theclaw Posted January 27, 2011 Share Posted January 27, 2011 (edited) I don't see much info on the subject, perhaps because the system is most prevalent in America where almost no one's TV set is RGB equipped. And even then many won't accept low-res over component either. I'm not familiar with how 2600 draws its graphics. IIRC it takes a pretty complicated hack to tap even composite. Let alone svideo. I dare think what monstrosity may be needed for better than that... Eek. I'm not saying necessarily original hardware though. A 7800 or something else generally compatible would be interesting in its own way. Edited January 27, 2011 by theclaw Quote Link to comment Share on other sites More sharing options...
R.Cade Posted January 27, 2011 Share Posted January 27, 2011 Not with original hardware- the TIA doesn't process video in RGB. Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted January 27, 2011 Share Posted January 27, 2011 You'd need to determine the colour phase and produce RGB values from that. Quote Link to comment Share on other sites More sharing options...
CGQuarterly Posted January 27, 2011 Share Posted January 27, 2011 I play all of my games in RGB. I have my VCS s-video modded with the Longhorn Engineer kit, and it looks almost as good as RGB. So if you are looking for increased video quality, you should just go with that. Chris Quote Link to comment Share on other sites More sharing options...
theclaw Posted January 27, 2011 Author Share Posted January 27, 2011 Great. I'll keep it in mind. I may ask sometime about acquiring an s-video modded Jr or 7800 (whichever is most compact in size compared to the dusty old VCS I've got around).

mimo Posted January 27, 2011 Share Posted January 27, 2011 my french 7800 does a good job with RGB, I believe there were some French 2600 juniors that have RGB output too. Of course they are PAL consoles though Quote Link to comment Share on other sites More sharing options...
A.J. Franzman Posted January 28, 2011 Share Posted January 28, 2011 (edited) Those French consoles may have a SCART plug, but the output is not RGB unless someone put a Y/C to RGB converter inside there. NTSC and PAL TIA ICs (which are also used in SECAM consoles) produce Luma + Chroma output only. Edited January 28, 2011 by A.J.

A.J. Franzman Posted January 28, 2011 Share Posted January 28, 2011 OK, so still an after-the-fact conversion. The output may be RGB, but the image quality is no better than S-video. Quote Link to comment Share on other sites More sharing options...

The output may be RGB, but the image quality is no better than S-video. maybe so, but after trying many different s-video conversions on 7800's and 2600's this is far far superior. The picture quality is pin sharp, no overdriven colour, no vertical banding, no colour bleed etc etc Quote Link to comment Share on other sites More sharing options...
theclaw Posted January 28, 2011 Author Share Posted January 28, 2011 Wait a second... I forgot my external HDMI scaler has s-video input! I dunno quite how that'd turn out, but no matter what it will crush anything RF could ever hope. Especially on my large LCD for the most blatant of reasons: it's a model without RF input (not kidding). lol. Quote Link to comment Share on other sites More sharing options...

ApolloBoy Posted January 31, 2011 Share Posted January 31, 2011 Has anyone been able to figure out the RGB encoder board on the French 7800? If someone out there made an RGB board based on the one used in the French 7800, I'd be all over it! Quote Link to comment Share on other sites More sharing options...

If someone out there made an RGB board based on the one used in the French 7800, I'd be all over it! Its done by a Sony V7021. I'm pretty sure they are obsolete by now and therefore hard/expensive to get hold of. Quote Link to comment Share on other sites More sharing options...

I'm not familiar with that part but I had a quick look at the datasheet and it works the other way. It takes in RGB and creates a composite signal from it.
