Sega Genesis SCART RGB to Component Issues (p.3 for Update)

[Ben]

Well I got everything and the results were not good on my HDTV CRT. (Not sure what the term is for this) When there is white text in a dark background, I get a dark horizontal bar of where the text is. And I get grainy text that moves. Also, had trouble syncing the "Segggaaa" white screen during sonic 2.

I think the issue is because I am using it on an HDTV. The FPS looks lower (perhaps tv having trouble processing RGB to component). It looks like I am playing on an emulator.

I am going over a friends house later to test it on his SDTV CRT. You think I can expect different results?

If not, it looks like a sync issue then... Should I try to return this raw sync scart from ebay and buy a composite sync?

EDIT: Just tried on on my big screen TV, same issue with the the dark horizontal bars. Though, it was not as noticeable. However, there wasnt as much lag and the fps was higher. There seemed to be some sync or connectivity issue. Because I would get a "no signal" screen during the load screens on sonic. I think the CSY 2100 has to get warmed up or something because it wouldn't happen after that even if i reset it.

I can only speak to the HDTV issue: If I just just use my CYP SCART to Component converter plugged into component, I have the same problems, screen flicker and odd lines. It will only work properly on my older CRT tv. If I play my Genesis or Saturn on my HDTV, I don't even use the CYP converter, I just plug my SCART cable directly into the XRGB-3 (which has scart input of course) and it then upconverts to 1080p. Personally, I prefer the look of the games on a CRT converted to component rather than upscaled from the SCART on an HDTV, but that's just me.

Well I tried it on my friend's non HD CRT, same issue, just not as extreme. Sometimes the screen will shake during game play, but I would just reset and it would start working again. The screen will still scroll/shake during bright white screens though.

Here are the issues I am having:

1) I get those dark bars. Also, these black bars are not just resulted from texts, it is from regular animations too (example: If I jump my character through the air, it will result in a horizontal bar of where the character is vertically).

2) There is trouble rendering white screens. The White Sega load screen on Sonic start up would scroll from bottom to top. In Adventures of Batman and Robin, when I pick an item that destroys all enemies (the animation is basically a white flash) the screen will shake, like the Sonic White Loading Screen.

3) The very bottom of the screen will warp. It looks like it happens on bright screens. This was tested during Vectorman. I took out the Red and Blue cable, and the issue still existed, so it looks like it is an issue with luma/sync.

Here are some pictures from my HDTV CRT so you can get an idea of the black bar issue I was talking about before:

This is on Composite (no black bars, good):

This is Component (black bars, bad):

Here are some videos using the converter on my friends non HD CRT (disregard the grey shade going up and down, CRTs always show that in videos):

Here is the white screen issue during the Sonic White Loading Screen:

Warped bottom/Vectorman issue (notice how the text gets slanted):

When I pause: (notice that when I pause the game, the game dims itself, and nothing is warped anymore. When I unpause, screen goes bright again and warps start again)

You can't really see the black bar issue here, but it is there, especially in person:

At this point, I don't really care about getting it to work on my HDTVs, I just want it to work on a non HD CRT, because down the line, that is what I want to use (non HD CRT). And my CRT HDTV doesn't actually handle composite that bad compared to the component (the composite on my HDTV looks better than the composite of my friend's SD). Composite is less sharp of course, but no fps drop, no sync problems, and the screen is actually brighter. I actually wasn't really impressed with component on my HDTV. I was on my friend's non HD CRT though. So I am fine with using composite on my HDTV.

It would be nice to get it to work fine on all my units, but I want to get this to work on a non HD CRT for sure.

Here are pictures of the converter if needed:

I was thinking I should try a composite sync SCART cable instead of a raw sync SCART Cable??

I would get that buzz sound on this cable sometimes too, which I never get on new cables. Possible Cable issue?

Or are these all common issues when using a RGB to Component converter and there is nothing I can do?

I would love to get a perfect component signal on the non HD CRT.

My first thought was the capacitors in the SCART cable, or the need for resistors in it. I had a similar problem tho not so pronounced on my SNES with bright colors and needed to swap out the SCART cable.
Here's some stuff to read on neo-geo.com's forum.

@sp957

As far as your cables go, I'm no expert, I just got into using SCART a few years ago. But in terms of the Saturn and Genesis/Master System, those cables from retrogramingcables that I linked you have worked perfectly for me. I have none of the issues you've described with them, and couldn't be happier. BUT, here's the dilemma with that: I use a different SCART to component converter than you. So it seems to me your problem is either the cables or converter, my hunch is that it's probably the cables since any time you are using an unofficial cable it tends to be a crapshoot. So, if you can afford it, I would say try the cables first, and then if that doesn't fix it switch out the converter. I can vouch for the CYP and it's the one that Joe Redifer (from Game Sack who posts in the Videos forum) uses, so if it turns out the cables aren't the problem I think it would be well worth investing in one.

Thanks.

Going to try another cable first.

It does look like my converter is different. I thought I bought the CSY 2100, but might looks like the clone version. Did some research, and everyone says it does the same job. I haven't seen anyone say the clone caused any issues yet.

Anyone know another good place to get a cable? the eBay seller only sells raw sync cables, and I think I should try composite sync version.

I use these guys for all my cables (when official aren't available), haven't had a problem yet.

EDIT: Also, they have cables for all of the Sega consoles, they just aren't all on that drop menu on the left. They need to set up the site better, here is the Sega page: http://www.retrogamingcables.com/sega.html

* One thing I noticed, they seem to be out of stock on the Saturn SCART cable with 2 channel audio leads. Some of the SCART to component converters have audio out ports on them, but if yours doesn't you may not want to go with their Saturn cable. Their Genesis/Master System cables are still in stock with the 2 channel leads though.

2nd EDIT: Also, this cable - http://www.retrogamingcables.com/sega-m ... build.html is supposedly the holy grail of Genesis SCART cables. It's been out of stock forever, I'm watching like a hawk for them to get more but they go for crazy money on ebay. If you absolutely want to know you have the best cable possible, that's the one to get though. I have their cheaper one that I linked earlier and it's perfectly fine, so I wouldn't go crazy bidding on that one.

Nice.

Yea, I have a Genesis model 2. I dont have the model 1, and if I did, I wouldnt spend 60+ bucks on a cable lol. I was more than happy with how the current cable looked on the non HD CRT. Just trying to get those issues gone.

I was thinking about this one then:

http://www.retrogamingcables.com/sega-m ... sound.html

It looks identical to the SCART cable I have now, but it has a little differences so maybe it will fix my issues. The RCA audio looks higher quality for sure.

I sent them a message asking if these cables use composite or raw sync. In the meantime, just in case they take a while to answer, do you know what kind of sync they use?

Also, were you actually able to find a official Sega Genesis SCART cable?


Lastly, sorry guys, I should have mentioned this before. But I decided not to bother with Saturn's RGB SCART for now. I tried S-Video on my friends non HD CRT, and S Video looked like HD to my eyes lol.

I have to be honest, I don't know about the sync on those cables. I just bought them, they worked with my converter, and I was good to go. They list the more expensive one as "Pure Sync", but I don't know if that is supposed to mean raw sync or what. I would say just email them.

Also, there was an official SCART cable released in France supposedly. I have never seen one for sale, or know the details regarding one, I just read that many years ago on the old GameFan site.

The cables are still remarkably affordable there.
But they need to be modified for other models. (page in French).

Wow, thanks for the link. I don't suppose you would know if these would offer a noticeable advantage over the retrogamingcables ones (specifically that $65 Packed-A-Punch model)? I speak zero French and couldn't solder to save my life, but it seems to me if they are superior some ebay entrepreneur could buy a bunch and modify them for US usage at a decent profit.
